Selected amides of fatty acids with 16-18 carbon atoms in mol. and mol. weight of 300-400 were investigated to find a perspective ecol. supplement to corrosion inhibitors used nowadays in acidic environments. Weight-loss, potentiodynamic polarization, impedance spectroscopy and hydrogen penetration were among the methods used in the study. Results show that good protection can be expected from all organic compounds investigated. Inhibition efficiency of 90-97% at room temperature can be expected. Effectiveness is decreased with increasing temperature Addition of inhibitor into solution also affects hydrogen transport through the carbon steel sheet material.

Takeda, S. published the artcileCationic flotation of quartz from an artificial mixture with hematite using hexylamine, Category: catalysis-chemistry, the publication is Colloids and Surfaces (1988), 29(2), 221-32, database is CAplus.

The cationic flotation of quartz was carried out from an artificial mixture (1:1 by weight) of fine grained (-10 ¦Ìm) quartz and hematite, using hexylamine acetate (HAA) and dodecylamine acetate (DAA) as collectors. Selective flotation of quartz was possible in the pH range 9-10 using HAA. The adsorption densities of DAA and HAA on quartz and hematite were measured at pH 9.8 and the relation between the flotation behavior of both minerals and the surface coverage of collectors was established. Complete flotation of quartz and hematite required a surface coverage (¦È) of DAA of ?100% at pH 9.8, while complete flotation of quartz took place at ¦È ? 10% with HAA. The flotation behavior with DAA was explained by considering the adsorption of undissociated free amine. Zeta potential measurements were incorporated to interpret the difference in the adsorption behavior of both collectors on quartz and hematite.

Takeda, Susumu published the artcileFlotation separation of coarse-grained quartz from a mixture with hematite fines in alkaline media in relation to the adsorption of dodecylammonium acetate, Application In Synthesis of 2016-56-0, the publication is Nippon Kogyo Kaishi (1987), 103(1198), 859-64, database is CAplus.

Flotation separation of coarse-grained quartz with dodecylammonium acetate as the collector is interfered with when fine-grained hematites coexist. The reason for this was investigated. Both quartz and hematite become hydrophobic by adsorption of dodecylammonium acetate, and the hematite fines coat the surfaces of the quartz grains. The slime coating may cause the depression of quartz flotation.

The leaching red residue from a Zn smelter contains 6-10% Pb as Pb-SO₄. Zn ions are removed by washing and residual flocculant is removed by attrition grinding. The flotation pulp is heated to 35-45¡ã and treated with C_12-16 amine acetate and Na hexadecyl sulfate.

Tsunekawa, Masami published the artcileInterfacial characteristics of barite, calcite, and scheelite in aqueous solution, and their flotation, Category: catalysis-chemistry, the publication is Nippon Kogyo Kaishi (1981), 97(1118), 251-6, database is CAplus.

A surface chem. study was made on the floatability of barite??[13462-86-7] and calcite??[13397-26-7] and scheelite??[14913-80-5] with dodecyl?ammonium?acetate (DAA) [2016-56-0] and sodium?dodecyl?sulfate (SDS) [151-21-3]. Floatability of barite changed when pH deviated from the equivalence point, EP (pH = 7.6), due to the surface hydrolysis. EP compared well with the isoelec. point. Barite was well floated with SDS, irresp. of pH, because of the chem. adsorption of SDS. The flotation of calcite changed considerably with pH, due to the change in the concentration of chem. species in the aqueous phase with pH.

Wang, Li published the artcileAdsorption mechanism of mixed anionic/cationic collectors in Muscovite – Quartz flotation system, Application of Dodecylamineacetate, the publication is Minerals Engineering (2014), 44-50, database is CAplus.

The flotation separation of muscovite from quartz was investigated using mixed sodium oleate/dodecylamine acetate (NaOL/DDA) collectors. The experiments were conducted on single minerals and on a mixture of minerals, and their collecting performances were studied by means of Fourier transform IR (FTIR) spectroscopy, zeta potential technique and XPS. Neither muscovite nor quartz is floated with NaOL alone, while using DDA alone, they can be separated only at strong acid conditions (pH < 3). Mixed NaOL/DDA collectors exhibits excellent performance in the flotation separation of muscovite from quartz at pH 10. The ratio of the mixed collectors is found to be an important criterion in the flotation tests. The best separation result (muscovite recovery of 80% and quartz recovery of 10%) could be achieved with NaOL/DDA molar ratios of 3/1 and 2/1 at pH 10. The co-adsorption of NaOL and DDA is found on muscovite surface by strong electrostatic interaction, H bonding and chem. adsorption. This study may provide guidance for the flotation mechanism and application of mixed anionic/cationic collectors.
