摘要
作为重要的有机化工中间体,乙硫醇广泛应用于医药、工业、农业等领域。针对乙烯-硫化氢催化加成合成乙硫醇的固体酸催化剂,探讨了性质、改性方式及其乙烯硫化反应机制。分析认为:酸性位点是乙烯硫化合成乙硫醇的活性中心,强酸位和弱酸位浓度的平衡则决定着固体酸催化剂的稳定性;对于改性氧化铝和金属硫化物催化剂,改性金属与载体间的相互作用是影响反应活性的重要因素。
As an important organic intermediate of chemical industry,ethyl mercaptan is widely used in medicine,industry,agriculture and other fields.For the solid acid catalyst for the synthesis of ethyl mercaptan by catalytic addition of ethylene and hydrogen sulfide,the properties,modification methods and the mechanism of ethylene sulfidation reaction were discussed.The analysis indicates that the acid sites are the active center of ethylene sulfidation to form ethyl mercaptan.The balance between the strong acid site concentration and weak acid site concentration determines the stability of solid acid catalyst.For modified alumina and metal sulfide catalysts,the interaction between the modified metal and the support is an important factor affecting the reaction activity.
