Nozaki, Toru published the artcileComplex formation of nitrilotris(methylene)tris[phosphonic acid] and flotation with the complexes, Recommanded Product: Dodecylamineacetate, the publication is Nippon Kagaku Kaishi (1988), 1017-20, database is CAplus.

From the polarog. behavior of Cu(II), Pb(II), Cd(II) and Mn(II) in nitrilotris(methylene)tris[phosphonic acid] (NTMP, H₆L) solutions at an ionic strength of 0.4 adjusted with sodium perchlorate, the species of the metal complexes and their stability constants were determined In the pH ranges from 3.4 to 4.9 for Cu, 3.5 to 4.5 for Pb, 4.5 to 5.0 for Cd and at pH 5.6 for Mn, the species of MH₃L^–, MH₂L^2- and MHL^3- were ascertained and the logarithms of their overall stability constants at 25¡ã were determined Flotation of NTMP by complexing with Fe(III) and the NTMP complexes of Cu(II), Pb(II), Cd(II) and Mn(II) was investigated in a cell (20 ¡Á 2.7 cm I.D.). Recoveries of 4.0 ¡Á 10^-4 mol/dm³ of NTMP and 1.6 ¡Á 10^-4 mol/dm³ of the NTMP complexes were 100%, and 98.8, 97.9, 92.8 and 81.2%, resp., by using 1.2 ¡Á 10^-3 mol/dm³ of dodecylammonium acetate (DAA) for the former and 8.0 ¡Á 10^-4 mol/dm³ of DAA for the latter, as surfactant at pH 7.0. 1420 Ppm of Cl^–, 196 ppm of SO₄^2- and 3100 ppm of NO₃^– did not interfere with the flotation. It seems that the flotation of NTMP and the complexes proceeds through the formation of the ion pair R_n?MH_i?L, where n? = 6-n–i?, and R and n denote the cation of DAA and the charge of the metal, resp.

Duperray, Florence published the artcileExcretion of glutamate from Corynebacterium glutamicum triggered by amine surfactants, Category: catalysis-chemistry, the publication is Biochimica et Biophysica Acta, Biomembranes (1992), 1103(2), 250-8, database is CAplus and MEDLINE.

C. glutamicum is used for the industrial production of glutamate. Excretion of the amino acid may be induced by various means. The characteristics of glutamate excretion induced by 2 amine surfactants, dodecylammonium acetate (DA) and dodecyltrimethylammonium bromide (DTA) were analyzed. Addition of these surfactants induced an immediate efflux of internal glutamate. It also induced a perturbation of the energetic parameters of the cell (decrease of ¦¤¦Ì?_H, decrease of the internal ATP concentration). The efflux was not the result of these perturbations: glutamate is taken up by the cells via an ATP-dependent unidirectional active transport system and no efflux took place as a consequence of an artificial decrease of the energetic parameters. In addition, amine surfactants also induced an excretion of other species, in particular potassium. The possibility that the effluxes result from a permeabilization of the lipid bilayer was tested by analyzing the interactions between the surfactants and liposomes.

Soto, H. published the artcileSelective flotation of phosphates from dolomite using cationic collectors. I. Effect of collector and nonpolar hydrocarbons, Computed Properties of 2016-56-0, the publication is International Journal of Mineral Processing (1986), 16(1-2), 3-16, database is CAplus.

The flotation behavior of francolite and dolomite with a variety of cationic collectors was studied. Only primary amines were strong collectors of the phosphate mineral. Dolomite was also floatable with primary amines, but from a mixture of francolite and dolomite, the primary amines were uniquely selective towards the phosphate mineral. Adsorption studies carried out with individual minerals showed that the collector was strongly adsorbed on both dolomite and francolite. However, in a phosphate ore, primary amines were adsorbed mainly on the phosphate, indicating that a stronger interaction existed between the amine and francolite than between the amine and dolomite. The use of hydrocarbon oils was beneficial not only in reducing the collector requirements, but also in accelerating the flotation rates.

Soto, H. published the artcileFlotation of apatite from calcareous ores with primary amines, COA of Formula: C14H31NO2, the publication is Minerals & Metallurgical Processing (1985), 2(3), 160-6, database is CAplus.

The role was studied of chem. reaction in the selective adsorption of primary amines on phosphate minerals. Kerosine decreases the collector requirement because the hydrocarbon is coadsorbed with the amine on the mineral surface. The heats of reaction of the aminium ions with phosphate, carbonate, and sulfate were measured. The primary amine ions react with the phosphate ions on the apatite surface because of the strong affinity of the 2 ions. If more amine than necessary to cover the apatite is added the amine is adsorbed by the carbonate and separation of apatite from carbonate mineral is more difficult.

Ueda, Naomi published the artcileImprovement of conservation for waterlogged woods using polyethylene glycol (PEG) (treatment with cationic surfactants), Recommanded Product: Dodecylamineacetate, the publication is Zairyo (1992), 41(461), 148-52, database is CAplus.

In the conventional polyethylene glycol (I) method for conservation of waterlogged wood, it is sometimes difficult for I to penetrate into the wood, depending on wood species or the degree of deterioration, and shrinkage (e.g., maximum 20 ? 30% in tangential direction) or warp of specimens occurs. In order to maintain its dimensions and mech. strength, Akagashi (Quercus?acuta?Thunb.) wood was treated with some cationic surfactants which were easily adsorbed on cellulose and thus lowered surface tension of water. With the surfactant treatment it was expected that possible shrinkage accompanied by water evaporation could be decreased. The wood samples were soaked in a dilute cationic surfactant solution, followed by immersion in I solution with gradual increase of its concentration The variations of dimension and weight were monitored periodically. The surfactant treatment allowed I to penetrate easily into waterlogged wood. Furthermore, it was noticed that the shrinkage and change in shape could be minimized, and the dimensions were maintained without any significant change. In addition, by using the present treatment, one can expect that the penetration time in PEG treatment will be shortened.

Boethling, Robert S. published the artcileDoes the semi-continuous activated sludge (SCAS) test predict removal in secondary treatment?, Recommanded Product: Dodecylamineacetate, the publication is Chemosphere (1997), 35(10), 2119-2130, database is CAplus.

The SCAS test was formalized by the US Soap and Detergent Association in 1965. The SCAS procedure has also been adopted by the Organization for Economic Cooperation and Development as a test for inherent biodegradability and by the US EPA as a test guideline (40CFR 835.3120) under the Toxic Substances Control Act. To study whether the SCAS test may be used to predict removal in full-scale activated sludge treatment systems, we collected all available SCAS data for organic chems., and retrieved data from full-, pilot- or bench-scale continuous-feed activated sludge studies for the chems. that had SCAS data. The intersected file was subjected to statistical anal. Conclusions are: (1) SCAS data were strongly clustered at high (>90%) removal; (2) for SCAS removal >90%, it is probable that removal in the field will be >50%; (3) however, for SCAS removal <90% adequate treatability cannot be predicted with confidence.

Chao, Chen-Shen published the artcileStudies on fabric dye additives – dye additives for polyacrylic fibers, COA of Formula: C14H31NO2, the publication is Yingyong Jiemian Huaxue (1979), 2-8, database is CAplus.

In the dyeing of polyacrylonitrile fibers with Astrazon Yellow 3 GL, Astrazon Red GTL, and Astrazon Blue FRR in the presence of 21 cationic surfactants, 15 anionic surfactants, and 26 nonionic surfactants, alkylbenzyldimethylammonium chlorides, alkyltrimethylammonium chlorides, and alkylhydroxyimidazolines gave good results. Dyeing was improved by mixing the above cationic surfactants with C₁₆H₃₃(OCH₂CH₂)_nOH [9004-95-9], C₁₇H₃₅CO(OCH₂CH₂)_nOH [9004-99-3], or similar nonionic surfactants.

Zhang, Xiao-ping published the artcileHydrophobic aggregation of ultrafine kaolinite, SDS of cas: 2016-56-0, the publication is Journal of Central South University of Technology (English Edition) (2008), 15(3), 368-372, database is CAplus.

The hydrophobic aggregation of ultrafine kaolinite in cationic surfactant suspension was investigated by sedimentation test, zeta potential measurement and SEM observation. SEM images reveal that kaolinite particles show the self-aggregation of edge-face in acidic media, the aggregation of edge-face and edge-edge in neutral media, and the dispersion in alk. media due to electrostatic repulsion. In the presence of the dodecylammonium acetate cationic surfactant and in neutral and alk. suspension, the hydrophobic aggregation of face-face is demonstrated. The zeta potential of kaolinite increases with increasing the concentration of cationic surfactant. The small and loose aggregation at a low concentration but big and tight aggregation at a high concentration is presented. At pH = 7 alkyl quarterly amine salt CTAB has the best hydrophobic aggregation among three cationic surfactants, namely, dodecylammonium acetate, alkyl quarterly amine salts 1227 and CTAB.

Zhang, Xiao-ping published the artcileAggregation behavior of ultrafine kaolinite in water, Application In Synthesis of 2016-56-0, the publication is Zhongguo Kuangye Daxue Xuebao (2007), 36(4), 514-517, database is CAplus.

The change of pH and the effect of cationic surfactants on aggregation behavior of ultrafine kaolinite in the water were investigated by sedimentation tests and Zeta potential measurements. The exptl. results show that kaolinite particles aggregate when the pH of system is less than 7 and disperse when the pH of system is more than 9. With the addition of cationic surfactants, the value of Zeta potential of kaolinite increase and the aggregation effect is improved. The higher the surfactant concentration is, the more obvious the aggregation effect is. While pH is 7, the sediment yield of kaolinite decreases with the increase of length of alkylamine acetate chains. At the same concentration, the quaternary ammonium compounds produce better aggregation effect than alkylamine acetate.

Tsunekawa, Masami published the artcileRemoval of trace impurity from limestone using flotation techniques, Application of Dodecylamineacetate, the publication is Materials Transactions (2009), 50(1), 171-176, database is CAplus.

High grade limestone was obtained by removing trace impurities through reverse and carrier flotation techniques. A simple method for measuring the impurity content of limestone was developed by correlating the amount of impurities and the turbidity of suspensions of residue from limestone dissolved in 20% acetic acid. Impurity removal >50% with limestone recovery better than 85% was obtained under suitable conditions by both reverse flotation and carrier flotation using sodium oleate (NaOl) and dodecylammonium acetate (DAA) as collectors. Limestone containing >0.15% impurity was used as the carrier. These results suggest that limestone treated by flotation can be used as high quality limestone in paper manufacturing
