摘　　要：二甲基亚砜及二甲基砜是重要的溶剂和医药中间体,传统的生产技术存在安全隐患。近年来以二甲基硫醚为原料,双氧水为氧化剂制备二甲基亚砜/二甲基砜研究成为科研工作者关注的热点。包括以TS-1和金属氧化物为从催化剂的固定床连续工艺,不使用催化剂釜式反应工艺及管式、微通道的连续工艺技术。以双氧水和二甲基硫醚为原料生产二甲基亚砜的新技术将取代传统的二甲基亚砜/二甲基砜生产工艺。Dimethyl sulfoxide and dimethyl sulfoxide are important solvents and pharmaceutical intermediates.Traditional production technologies have potential safety hazards.In recent years,the preparation of dimethyl sulfoxide/dimethyl sulfone from dimethyl sulfide as raw material and hydrogen peroxide as oxidant has become the focus of scientific researchers.It includes the fixed bed continuous process with TS-1 and metal oxide as the starting catalyst,and the continuous process technology without using catalyst kettle reaction process and tubular and microchannel.The new technology of producing dimethyl sulfoxide with hydrogen peroxide and dimethyl sulfide as raw materials will replace the traditional production process of dimethyl sulfoxide/dimethyl sulfone.
