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.

了臭氧氧化法去除工业废硫化氢、硫醇试验情况,考察了臭氧浓度、停留时间和催化剂等不同因素对去除率影响。

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.

试验结果表明能达到较好去除效果,硫化氢、硫醇最终氧化产物可以不是二氧化硫,而是凝聚态硫化物。

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.

对可用于各种调味香精食用香料硫代乙酸甲酯合成进行了初步研究，产率达到693％，对所合成产品做了红外光谱分析和质子核磁共振分析，确定了其化学结构。
