Mamiya, Mitsuo published the artcileSelective flotation of lithium tantalate from green carborundum. Recycling of slicing dusts of advanced functional materials, Name: Dodecylamineacetate, the publication is Nippon Kogyo Kaishi (1988), 104(1207), 581-6, database is CAplus.

The flotation separation of LiTaO₃ (I) from green carborundum (A) slicing dust was investigated. Only with surfactant were both I and A floated at any pH. Floatability of I was enhanced by HF with use of dodecylamine acetate at pH 2, whereas that of A was depressed by gum arabic. Application of this method to slicing dust containing 9.9% I gave 91.2% recovery of I with 70.8% purity in the froth.

Krut’ko, N. P. published the artcileEffect of surfactants and hydrocarbons on physicomechanical properties of granulated potassium fertilizers, SDS of cas: 2016-56-0, the publication is Vestsi Natsyyanal’nai Akademii Navuk Belarusi, Seryya Khimichnykh Navuk (2006), 72-77, database is CAplus.

The effects of granulated KCl fertilizer hydrophobization on granule water absorption and KCl solubility were studied with the aim to find treatments improving the granule transport and storage stability and resistance to caking. The granules were treated with C₁₂-C₁₆ aliphatic amines in free or salt (acetate, chloride) forms, with free fatty acids (C₄, C₅, C₆, C₇, oleic, linoleic, linolenic), with fatty acid tech. mixtures, petroleum hydrocarbons, and their combinations. Free amines and their acetate salts were more effective in hydrophobization than chloride salts; the effects also increased with the amine chain length. The fatty acids were inferior to amines in the hydrophobization effects. Combined treatments with fatty amines, fatty acids, and non-polar hydrocarbons were very effective in waterproofing the KCl granules, providing up to 60% hydrophobization and 96-97% dynamic strength.

A procedure for detection of bacteria degrading cationic surface-active substances (CSAS) was developed. The procedure is based on the color of pyrocatechin violet, an organic dye, changing from green-blue in the presence of CSAS to red-brown in its absence. After application of pyrocatechin violet to bacterial macrocolonies grown on a synthetic medium with a CSAS as the only source of C, red-brown zones develope around the colonies, which is indicative of CSAS degradation A total of 55 strains of bacteria degrading undecylpyridinium bromide were isolated from water and sewage purification plants. Six bacterial strains degraded all 9 surfactants tested. Degradability was related to the presence of a long C chain, with branching, and a substituent in the aromatic ring. The procedure may be used for the rapid determination of degradation of CSASs with different chem. structures.

Dikhtievskaya, L. V. published the artcilePMR-spectroscopic study of solubilization of organic compounds by micellar solutions of aliphatic amines, Synthetic Route of 2016-56-0, the publication is Vestsi Akademii Navuk BSSR, Seryya Khimichnykh Navuk (1989), 21-4, database is CAplus.

NMR spectra for aqueous micellar solutions of C₁₂-C₁₈-aliphatic amine acetate surfactants modified by solubilization of oleophilic organic compounds showed that the action of the solubilizate on the structure and ionic-mol. composition of the micellar solutions depended both on the length of the hydrocarbon portion of the surfactant and on the nature of the solubilizate. For C₁₂ and C₁₄ amines, the greatest structure changes were observed during colloidal dissolution of heptanol, caprylic acid, and ¦Á-naphthol. Heptane, naphthalene, and benzene had little or no influence on the micellar structure. C₁₆ and C₁₈ amines were more susceptible to the changes than C₁₂ or C₁₄ amines. In the case of C₁₈ amine, practically all of the solubilizates caused loosening of the micelle and increased ionization of polar groups. In sylvinite ore enrichment by flotation, the addition of oleophilic compounds had the greatest effect on C₁₈ amine in increasing its flotation activity.

Badawi, A. M. published the artcileSurface and biological activity of some novel cationic surfactants, Application of Dodecylamineacetate, the publication is Journal of Surfactants and Detergents (2007), 10(4), 243-255, database is CAplus.

In this study, steps were taken toward the development of bactericidal and fungicidal synthetic cationic surfactants by reacting decyl-, dodecyl- or tetradecylamine with acetic or hydrochloric acid to produce a series of amine salts which consequently converted to copper or cobalt cationic complexes via complexing the first series compounds with copper (II) or cobalt (II) ions. Surface properties such as interfacial tension and emulsifying power of these surfactants were investigated. The surface parameters including critical micelle concentration (CMC), maximum surface excess (¦£_max) and min. surface area (A_min) were studied. Free energy of micellization (¦¤G^o_mic) and adsorption (¦¤G^o_ads) were calculated The antimicrobial activity was determined via the inhibition zone diameter of the prepared compounds, which measured against five strains of a representative group of microorganisms. FTIR spectra, elemental anal. and H¹ NMR spectrum were performed to confirm compound structure and purity.

Jezequel, D. published the artcilePotentiometric study of the stability of ¦Â-cyclodextrin surfactant complexes, Category: catalysis-chemistry, the publication is Canadian Journal of Chemistry (1991), 69(12), 1865-71, database is CAplus.

The complexation constants K of ¦Â-cyclodextrin with 13 ammonium surfactants were determined by a potentiometric method using electrodes selective to amphiphilic ions. Especially for C_12-16-alkyl groups, a model that provides for the formation of a second complex, with a K₁/K₂ ratio of ?600, provided a good fit with the exptl. curves. There was a poor influence of the polar group, for example in the case of the dodecyl chain. On the other hand, the pK₁ values and the hydrophobic tail length were linked by a linear relation up to C₁₂; beyond pK₁ tended to be proportionally smaller and pK₂ more important.

Gu, Feng published the artcileRecovery of yttrium aluminum garnet from rock powder by flotation method, HPLC of Formula: 2016-56-0, the publication is Shigen to Sozai (1992), 108(10), 713-17, database is CAplus.

YAG (Y-Al garnet) dust was recovered from the rock powder containing green carborundum (GC) by flotation process using dodecyl ammonium acetate (DAA) as a cationic collector, or Aero Promoter 845# (Mitsue Cyanamide Co.) as an anionic collector. A 5-g powder mixture (YAG(sp. surface area 2.20 m²/g)/GC(0.59 m²/g) = 1/4) was studied using a 200 cm³ Denver flotation tester under the routine operating conditions described previously (CF: F.Gu, I. Matsuoka, and M. Mamiya 1991). Influences of collector, acid (activator, pH), and depressor concentrations on zeta potentials and flotation recoveries of YAG and GC are presented and discussed. About 90% recovery of YAG can be obtained by 3 ¡Á 10^-4 mol/dm³ concentration of DAA, 20 mg/dm³ corn starch as a depressor for GC, and 10^-1 mol/dm³ H₂SO₄ or H₂C₂O₄ as an activator. The oxalic acid is favorable with respect to high-grade flux. The AP845# was absorbed preferentially on the YAG surface, and can be used as an effective collector at 1.5 ¡Á 10^-5 mol/dm³ and pH 1.5 ? 2.5, and 90% recovery was attained by 5 mg/dm³ corn starch and 4 mg/dm³ ¦Á-terpinol.
