摘　　要：选取正丁硫醇、异丁硫醇、正己硫醇和叔辛硫醇为模型硫化物，采用高压釜法研究了以上硫化物在200℃～350℃时对铜粉、铁粉的腐蚀性．研究发现。硫醇对两种金属粉末的腐蚀性与反应温度以及该硫醇自身的结构有关．温度越高，硫醇的腐蚀性越强；硫醇越容易分解，其腐蚀性也越强．N-butylthiol, isobutylthiol, n-hexylthiol and tert-octylthiol were used as model mercaptans to study the corrosivity of mercaptans to metal powder. All the tests were carried out in a pressured reactor at a temperature range 200-350℃. The results indicated that the corrosivity of mercaptans was related to temperature and the structure of the mercaptans. The corrosivity of a mercaptan became strorger when the temperature goes higher for that the mercaptan decomposes much easily.
