摘要：
Oxidation of dimethylsulfide using atmospheric oxygen at 120 to 150 degree C was studied under a pressure of 2 to 5 MPa in the presence of a copper phenate catalyst (output up to 1000 mole dimethylsulfoxide calculated as 1 g multiplied by (times) atm Cu/hr). Kinetic equations established that the reaction for oxygen is zero order and for dimethylsulfide, first order. Selectivity for dimethylsulfoxide is close to 100%, independent of reaction conditions at a dimethylsulfide conversion lower than 80%, at higher conversions secondary reactions of oxidation of dimethylsulfoxide take place.
