〗 The hydrogen sulfide, methanthiol, dimethyl disulfide and methyl sulfide in air were effectively absorbed by TANEX tubes which frozen at -70 ℃ with solid CO2 and then determined by GC/PFPD with thermal desorbed equipment on 120 ℃. The experimental conditions were optimized. The detection limits range of 4 organic sulfur compounds was from 0.1 ng to 0.5 ng. RSD range of standard tube was from 12.7% to 16.3%. Spike recovery range of air was from 78.3% to 87.7%.

The catalytic transformation pathway can change to decrease the yield of hydrogen and yield methyl-contained sulfides such as methyl mercaptan, dimethyl sulfide and dimethyl disulfide, but overlarge concentration of methanol would holdback the transformation of isobutyl mercaptan. The transformation of isobutyl mercaptan was favorable if the volume ratio of methanol and benzene was 0.2.The addition of methanol assume certain effect on the catalytic cracking of di-n-butyl sulfide in solvent benzene but without changing the cracking reaction mechanism of di-n-butyl sulfide.
甲醇也可以使异丁硫醇的催化转化路径发生改变降低硫化氢的产率，生成甲硫醇、甲硫醚及二甲基二硫化物等含甲基硫化物，但甲醇的浓度过高会抑制异丁硫醇的转化，在反应体系中当甲醇的体积占到溶剂苯体积的20%时对异丁硫醇的转化较为有利；甲醇的添加对丁硫醚在溶剂苯中的催化裂化有一定影响，但没有改变丁硫醚的裂解反应历程。
