摘要
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.
