The cooperative effect of organic solvents in recovering fine mineral particles by liquid-liquid extraction was studied. With dodecylamine acetate as a collector, iso-octane as the main oil phase, and n-butanol and Me iso-Bu ketone as sub-oil phases, the cooperative effect between polar neutral organic mols. and non-polar hydrocarbon oil droplets on the extraction of fine quartz from the aqueous phase into the oil phase was estimated The oil/water interfacial tensions and contact angles of oil droplets on a quartz surface in water were measured. The neutral organic mols. made extraction of the fine quartz particles more efficient, i.e., by increasing the recovery of quartz in the oil phase and decreasing the collector addition Co-adsorption of the neutral organic mols. with collector ions plays the most important role.

Hu, Bo published the artcileRecovery of fine mineral particles by liquid-liquid extraction, Computed Properties of 2016-56-0, the publication is Shigen to Sozai (1993), 109(1), 17-22, database is CAplus.

The effect of organic phases on the recovery of fine quartz particles was studied using dodecylamine acetate (DAA) as a collector in a liquid-liquid extraction process at various pH values. Three kinds of organic solvents, i.e., BuOH, MeCOCH₂CHMe₂, and isooctane, were used as the oil phase. The interactions between the oil droplets and the quartz surface at different pH values and DAA concentrations were examined through related experiments on oil/water interfacial tension, contact angle, and interfacial free energy for contact. Good correlation was obtained between the quartz recovery and these variables. The recovery depended not only on the pH and the collector concentration, but also on the properties of the oil phase.

Fine particles of monasite, xenotime, and zircon were recovered from beach sand by liquid-liquid extraction in an isooctane-water system in the presence of surfactants (Na oleate, Na dodecylbenzenesulfonate, Na dodecylsulfate, dodecylammonium acetate and dodecylammonium chloride). Zeta potential variations were measured as a function of pH for each of these minerals to determine its isoelec. point for selecting the optimum mineral recovery conditions.

Kohga, Makoto published the artcileEffects of addition of surfactants on viscosity of uncured ammonium perchlorate/hydroxyl-terminated polybutadiene propellant, Formula: C14H31NO2, the publication is Kayaku Gakkaishi (1998), 59(4), 167-173, database is CAplus.

For the preparation of ammonium perchlorate (AP)/hydroxyl-terminated polybutadiene (HTPB) composite propellant, the lower viscosity of uncured propellant during mixing and casting is desirable. In this study, the effects ot the addition of 11 kinds of surfactants on the viscosity of an uncured propellant are investigated. Sodium lauryl sulfate is the most effective to decrease the viscosity of the AP/HTPB mixture The apparent viscosity of the AP/HTPB mixture with sodium lauryl sulfate can be made 30% lower than that of the AP/HTPB mixture alone. The optimum added amount of sodium lauryl sulfate is 0.005 wt% to HTPB, in order to obtain the sufficient effect of decreasing the viscosity of AP/HTPB mixture The apparent viscosity of AP/HTPB mixture can be decreased by the improvement of the wettability between AP and HTPB prepolymer. The addition of sodium lauryl sulfate is effective to decrease the apparent viscosity of uncured propellant and to delay the pot life.

Cartledge, Emily M. published the artcileReplacing Synperonic N in the physical developer fingermark visualisation process: Pseudo-operational trial and parameter studies, Category: catalysis-chemistry, the publication is Forensic Science International (2021), 110916, database is CAplus and MEDLINE.

A reformulated phys. developer (PD) solution has been devised to replace the use of Synperonic N for environmental reasons. The performance of the replacement solution has proved promising in laboratory trials using planted fingermarks [1] however; this may not always represent how a reagent works on real world samples. This paper therefore explores the effectiveness of the decaethylene glycol monododecyl ether (DGME)-based PD formulation through a pseudo-operational trial. A range of naturally handled, porous substrates were processed, which totalled over 600 samples that had been previously treated with amino acid reagents (1,2-indandione (IND) or 1,8-diazafluoren-9-one (DFO) and ninhydrin). The trial was representative of the operational use of PD at the end of a processing sequence for porous exhibits. The results from the trial establish that DGME is an effective replacement detergent for Synperonic N in PD solutions and demonstrated the added benefit of using PD as a sequential treatment. Planted mark studies to assess the parameters of the DGME-based PD formulation are also included in this paper. These studies explored the preparation, processing and storage temperature required for the solution as well as the shelf life. The effectiveness of DGME-based PD on items that have been previously wetted was also investigated. These studies show the formulation is suitable for use in an operational laboratory and is therefore an effective replacement formulation for the Synperonic N-based PD.

Thomas-Wilson, Amelia published the artcileReplacing Synperonic N in the Physical Developer fingermark visualization process: Reformulation, COA of Formula: C14H31NO2, the publication is Forensic Science International (2021), 110786, database is CAplus and MEDLINE.

The Phys. Developer solution currently recommended for use in the United Kingdom for fingermark visualization uses two surfactants: n-dodecylamine acetate (nDDAA) and Synperonic N. Synperonic N is covered by the EU directive 82/242/EEC, which sought to phase out chems. with degradation products more harmful than their precursor. This study explores the replacement of Synperonic N with alternative detergents and examines their ability to produce clear, stable solutions that are effective at developing fingermarks. The critical properties of the detergents were investigated, such as the critical micelle concentration and the hydrophilic-lipophilic balance, and planted mark comparisons were performed on promising formulations. Tween 20 was deemed unsuitable due to the production of cloudy solutions and the requirement to age the formulation to improve effectiveness. Brij C10 produced clear formulations; however, these were too stable causing unacceptably long exhibit processing times, and an addnl. preparation stage was necessary. Brij L23, Brij S10, Igepal CO-630, Polyoxyethylene (10) tridecyl ether and Tergitol 15-S-9 also proved to be unsuccessful alternatives. Decaethylene glycol monododecyl ether (DGME) was found to be a suitable alternative to Synperonic N and depletion series experiments suggested that a range of DGME and nDDAA detergent quantities were effective at developing marks. The processing time using DGME was similar to Synperonic N and the most favorable ratio of reagents is proposed in this paper as a reformulated Phys. Developer solution

Xue, Yulan published the artcileRecovery of gallium from neutralization precipitates by flotation, Related Products of catalysis-chemistry, the publication is Shigen to Sozai (1989), 105(12), 945-9, database is CAplus.

Ga(OH)₃, which was conventionally obtained as a residue of Zn hydrometallurgy, floated completely in water with a collector of Na dodecylsulfate (SDS) at pH 4-7.0 and did not float entirely with a dodecylammonium acetate (DAA) collector in the same conditions, while Ga(OH)₃ in an aqueous solution saturated with gypsum floated to some extent with either of the collectors. Because gypsum was quite floatable in these conditions, some depressants for the selective flotation of Ga(OH)₃ from gypsum were used and soluble starch and gum arabic were effective as a depressant for Ga(OH)₃ in DAA flotation. When DAA was used as a collector and soluble starch or gum arabic was added as a depressant, Ga(OH)₃ was effectively separated from gypsum and 91% of Ga(OH)₃ was kept in the tailing.

The adsorption of dodecylammonium acetate (DAA) on CAB-O-SIL was investigated; the adsorption isotherm of DAA shows two plateaus (i.e. LS-type). The addition of sodium chloride increases the adsorption of DAA, but no significant change can be found in the first plateau at low concentrations, while the addition of hydrochloric acid decreases the adsorption of DAA in the exptl. concentration region. The stability of CAB-O-SIL suspension was determined for the corresponding solutions Based on the two-step model of the surfactant adsorption theory proposed previously, and with the aid of conductivity measurements, the coagulation regularity of CAB-O-SIL suspension can be explained satisfactorily.

Huang, Wen published the artcileAggregation behavior of dodecylammonium carboxylates in carbon tetrachloride, HPLC of Formula: 2016-56-0, the publication is Huaxue Xuebao (1996), 54(10), 943-948, database is CAplus.

The aggregation of dodecylammonium acetate (DAA), dodecylammonium propionate (DAP) and dodecylammonium butyrate (DAB) were studied by an iodine spectrometric method and by H₂O solubilization. The (cmc)_I determined by the I method are 2.0 ¡Á 10^-4, 2.2 ¡Á 10^-4, and 4.3 ¡Á 10^-4 M, resp.; the (cmc)_W determined by H₂O solubilization are 2.0 ¡Á 10^-3, 3.5 ¡Á 10^-3, and 10.5 ¡Á 10^-3 M, resp. The (cmc)_I are lower by 1 order of magnitude than the corresponding (cmc)_W. The reason is probably that aggregates with low aggregation number which begin to form at (cmc)_I cannot solubilize H₂O. The H₂O solubilization starts only when the aggregation number of reverse micelles is high enough, which occurs at (cmc)_W (a concentration much higher than (cmc)_I). These experiments show that reverse micelles of DAA, DAP, and DAB are able to solubilize ¡Ü 4.3, ¡Ü 9.4, and ¡Ü 13.5 mols. of H₂O per surfactant mol., resp. According to a simplified spherical reverse micelle model, the aggregation numbers of the DAA, DAP, and DAB reverse micelles which solubilize the limiting amount of H₂O are 24, 122, and 252; the radii of the H₂O pools are 0.90, 2.02, and 2.90 nm, and the radii of the free H₂O pools are 0.33, 1.68 and 2.58 nm, resp.

The interaction between hydrophobic species plays an important role in the adsorption of surfactants. In this paper, naturally hydrophilic quartz and naturally hydrophobic talc were selected as model minerals for studying the adsorption of the cationic surfactant, dodecylammonium acetate (DAA). The effect of the hydrophobicity of minerals on the adsorption of DAA was investigated by measuring zeta potentials, adsorption densities and suspension stabilities as a function of pH in the presence of DAA.
