ABSTRACT:
The instant invention is directed to a process for removing odor from alkylthioethylamine reaction product mixtures having said odor. The process comprises first contacting an alkylthioethanamine reaction product mixture with a neutralizing amount of aqueous alkali metal hydroxide to form an organic phase and an aqueous phase. Next, the organic phase is separated from the aqueous phase. After separation, a sufficient amount of an aqueous hydrohalic acid is added to the organic phase to form an alkylthioethanamine hydrohalide which has reduced odor.
