1.And diallyl tetrasulfide was synthesized by the reaction of sulfur monochloride with allyl mercaptan with a yield of 81.

1.以一氯化硫和烯丙硫料合成二烯丙基四硫,产率81。

2.And diallyl tetrasulfide was synthesized by the reaction of sulfur monochloride with allyl mercaptan with a yield of 81.0%.

2.以一氯化硫和烯丙硫料合成二烯丙基四硫,产率81.0%。

3.This paper introduces experiment clearing away hydrosulfuric and mercaptan in waste gas from industry and o-zone, retention period, catalyzer and so on influence on removal rates.

3.介绍化法去除工业废气中的硫化氢、硫的试验情况,考察浓度、停留时间和催化剂等不同因素对去除率的影响。

4.The results show experiment have a higher removal rate and the last oxidize product of hydrothion and mercaptan is condensed state sulfide, could not be sulfur dioxide.

4.试验结果表明能达到较好的去除效果,硫化氢、硫的最终化产物可以不是二化硫,而是凝聚态的硫化物。

5.Methyl thioacetate was prepared by using acetyl chloride and methyl mercaptan as starting raw material in this paper.The yield of product is 69.3%.Itcan be used in seasoning flavor.

5.对可用于各种调味香精的食用香料硫代乙酸甲酯的合成进行初步研究，产率达到693％，对所合成的产品做红外光谱分析和质子核磁共振分析，确定其化学结构。
