Amine salts, especially acetate salts prepared by neutralization of a fatty amine with acetic acid, are useflil as flotation agents (collectors), corrosion inhibitors, and lubricants (3,8). Amine acetates are commercially available from a number of suppHers Akzo Chemicals Inc. (Armac) (73) Henkel Corporation (formerly General Mills) (Alamac) (74) Jetco Chemicals Inc. (The Procter Gamble Company) (fet Amine) (75) Sherex (Adogen) (76) and Tom ah Products (Exxon Chemical Company) (Tomah) (77). [Pg.223]

Benzyltriethylammonium chloride [56-37-1] is the most widely used catalyst under strongly basic conditions. Methyltrioctylammonium chloride [5137-55-3] (Ahquat 336, Adogen 464) is probably the least expensive catalyst. Others of high activity and moderate price are tetra- -butylammonium chloride [1112-67-0] bromide [1643-19-2] hydrogen sulfate [32503-27-8], tetra- -butylphosphonium chloride [2304-30-5], and other phosphonium salts of a similar number of C atoms. Many other onium salts can also be utilized. [Pg.187]

ClCH20Me, CH2CI2, NaOH-H20, Adogen (phase-transfer cat.), 20°, 20 min, 80-95% yield. This method has been used to protect selectively a phenol in the presence of an alcohol. ... [Pg.149]

CH2Br2, NaOH, H2O, Adogen, reflux, 3 h, 76-86% yield. Adogen = R3N CH3C1 , phase-transfer catalyst (R — Cg-C,o straight-chain alkyl groups). Earlier methods required anhydrous conditions and aprotic solvents. [Pg.170]

An early study of the attempted phase-transfer catalysed oxidation of dibenzyl sulphoxide to the sulphone using a variety of conditions and oxygen, periodate, hypochlorate and permanganate as oxidants showed that only potassium permanganate gave any of the required product, albeit in low yields. A further study, using Adogen 464 as... [Pg.985]
