    摘要: A tert-amine which contains an acid-activated color body precursor is treated to prevent it or a derivative thereof, e.g., an amine oxide, betaine, or quaternary ammonium compound, from turning pink when exposed to acidic conditions by contacting it with a dialkylacetal.

    摘要: Betaines are produced in solid form by reacting a tert-amine with a haloalkanoate salt when the reaction is conducted in a polar aprotic solvent in which the betaine is substantially insoluble. In a preferred embodiment, the tert-amine is an N-alkyldimethylamine, the haloalkanoate is sodium chloroacetate, and the solvent is ethyl acetate.

    摘要: A pourable amine oxide composition which is suitable for use in detergent compositions is obtained be reacting a tertamine with aqueous hydrogen peroxide in a nonionic surfactant as the sole organic solvent, at least a portion of the nonionic surfactant being a fatty alkanolamide corresponding to the formula ZC(O)NZ'Z" in which Z is an alkyl group containing 4-30 carbons, Z' is hydrogen or an alkyl or hydroxyalkyl group containing 1-3 carbons, and Z" is a hydroxyalkyl group containing 1-3 carbons. When the composition has a low water content, it is suitable for use in water-sensitive formulations, such as bar soaps and detergent concentrates.
