多效添加剂甲磺酸的制备及其机理探讨

PREPARATION AND MECHANISM PROBE OF METHANESULFONIC ACID

以二甲二硫为原料，在催化剂存在下，经Ｈ２Ｏ２氧化，一步合成甲磺酸．其转化率≥９９％，ＣＨ３ＳＯ３Ｈ的总收率为８４％，并提出了该反应的合成机理，较好地解释了实验中观察到的各种宏观现象．所得结果对甲磺酸的生产具有很好的指导意义．

Methanesulfonic acid has been prepared from dimethyl disulfide(DMDS) directly by the oxidation of hydrogen peroxide.This method transfoms DMDS above 99% into CH 3SO 3H the methanesulfonic acid yield is of 84%.The Mechanism of the reaction also been proposed,which explains the phenomena observed in the experiment property.
