摘要： The present invention relates to a process for producing chlorothioformate comprising reacting an alkenyl mercaptan with phosgene in a reactor in the presence of a carboxylic acid amide in an organic solvent, characterized in that the carboxylic acid amide is preliminary charged to the reactor in an amount of 10 to 50% by weight based on the whole amount of the carboxylic acid amide, and subsequently, the compound of the formula (I), phosgene and the remaining carboxylic acid amide are charged to the reactor.
