ABSTRACT:
A process for producing an aqueous solution of a straight-chain alkyl tertiary amine oxide and a branched-chain alkyl tertiary amine oxide by reacting aliphatic tertiary amines with an aqueous solution of hydrogen peroxide is disclosed. In this process, a tertiary amine which mainly consists of a branched-chain tertiary amine is first reacted with excess hydrogen peroxide, and then, a straight-chain alkyl tertiary amine which is substantially free of a branched-chain alkyl group is added to the reaction mixture for permitting further reaction with hydrogen peroxide. The process achieves a high overall conversion of the starting amines, and the final product has an extremely low level of residual hydrogen peroxide.
