| titleOfInvention | A kind of production technology of dimethyl sulfone |
| abstract | The invention belongs to chemical technology field, specifically discloses a kind of production technology of dimethyl sulfone, comprises the following steps：(1) oxidation reaction:Dimethyl sulfoxide (DMSO), oxidant and catalyst are added in reaction unit, controlling reaction temperature, stirring reaction generation dimethyl sulfone, the catalyst is 2,6 naphthalenedicarboxylic acids；(2) separation of solid catalyst；(3) crystallization generation dimethyl sulfone crystal；(4) separation of solid and liquid obtains dimethyl sulfone crystal；(5) dry.The present invention is by using 2,6 naphthalenedicarboxylic acids aoxidize the catalyst of generation dimethyl sulfone as dimethyl sulfoxide (DMSO), greatly accelerate the reaction speed of the oxidation reaction, and only need to separate solid catalyst, the crystallization for generating dimethyl sulfone and separation in last handling process, processing is then dried and can reach the high purity dimethyl sulfone product that purity is more than 99%.The present invention may be such that the energy consumption of dimethyl sulfone reduces using new catalyst, and the production cycle shortens, and production efficiency improves, economic benefit increase. |
