More Information
Summary:The invention discloses a synthesis method of tert-dodecyl mercaptan, which adopts a byproduct crude hydrogen sulfide of a coal synthesis gas device to control key impurities C2-C5 olefin, water and methanol in the byproduct crude hydrogen sulfide, and solves the problems of unqualified mercaptan production quality, low reaction conversion rate, unstable operation and easy catalyst deactivation in the mercaptan synthesis process. The method is simple and convenient to operate, low in cost and suitable for industrial application. 本发明公开了一种叔十二烷基硫醇的合成方法，采用煤制合成气装置的副产粗硫化氢，对其中的关键杂质C2-C5烯烃、水和甲醇进行控制，解决了硫醇生产质量不合格、硫醇合成过程中存在的反应转化率不高，运行不稳定、催化剂容易失活的难题。操作简单方便，成本低，适合工业化应用。
