N,N-二乙氨基硫代甲酰氯的制备

Preparation of diethylthiocarbamoyl chloride

在酸的催化下,铜试剂被 NaNO_2氧化生成四乙基秋兰姆,向四乙基秋兰姆的 CCl_4悬浮液中通 Cl_2气,除去硫磺和溶剂,得二乙氨基硫代甲酰氯。

Tetraethylthiuram disulfide(Ⅱ)was obtained by oxidizing sodium diethylcarbamate(Ⅲ)with NaNO_2 in HCl solution,diethylthiocarbamoyl-chloride(Ⅰ)was obtained by bubbling chlorinegas into the suspension of(Ⅱ)in CCl_4 in a flask,and removing sulfur and the solvent.
