A process for producing 2-mercaptoethylamine hydrohalides of the general formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are identical or different, and each represents a hydrogen atom, a lower alkyl group, a hydroxy-substituted lower alkyl group or a phenyl group, and X represents a halogen atom, which comprises reacting a 2-mercaptothiazoline of the general formula ##STR2## wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are as defined above, with a 2-halogenoethylamine hydrohalide of the general formula ##STR3## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 and X are as defined above, in the presence of water.
一种生产一般式为##STR1##的2-巯基乙胺氢卤化物的方法,其中R.sub.1,R.sub.2,R.sub.3和R.sub.4相同或不同,每个代表氢原子,低烷基基团,羟基取代的低烷基基团或苯基,X代表卤素原子,包括在水的存在下反应一般式为##STR2##的2-巯基噻唑啉(其中R.sub.1,R.sub.2,R.sub.3和R.sub.4如上定义),与一般式为##STR3##的2-卤代乙基胺氢卤化物(其中R.sub.1,R.sub.2,R.sub.3,R.sub.4和X如上定义)反应。
