苯硫醚合成路线

苯硫醚上游产品

苯硫醚下游产品

苯硫醚制备

将858g无水苯和464g三氯化铝混合，冷却到10℃，搅拌下加入405.1g氯化硫和390g苯配成的溶液。反应立即开始，逸出氯化氢，析出黄色粘稠的三氯化铝络合物。反应毕，将反应混合物冰析。分出苯层，蒸除苯后的深色油状物冷至0℃，滤除析出的硫。再将油状物溶于甲醇，冷却至0℃，再滤除析出硫。甲醇溶液在回收甲醇后继续蒸除少量低沸点馏分。然后收集155-170℃（2.39kPa）馏分，即为粗品。粗品用锌粉、氢氧化钠加热处理，水洗，干燥，最后进行减压蒸馏，得450-464g二苯硫醚。

1．氯苯法　以氯苯为起始原料，有与硫反应的方法和与硫化氢反应的方法。

2.二苯基二硫醚法
　将一定量的二苯基二硫醚和碘苯溶于醋酸乙酯中，用低压水银灯照射，产品收率１２％。
