In the laboratory, the experiment of adsorbing the single methanethiol by IVP indicated that the average penetrable adsorption capability is 11%. 在实验室用IVP活性炭对单一组分甲硫醇进行了吸附试验,测得平均穿透吸附容量为11%。
The synthesis method of methyl 3-( methylthio) propionate was reported in this paper. Methyl acrylate and Methanethiol are used as reaction materials, and piperidine is used as catalyst. The yield rached 82.0%. 对3-甲硫基丙酸甲酯的合成方法进行了研究.以丙烯酸甲酯和甲硫醇为原料,在哌啶催化下合成了3-甲硫基丙酸甲酯,产率达到82.0%。
Methanethiol is an important intermediate product of methionine by yeast metabolism and the precursor of dimethyldusulfide ( DMDS) and DMTS etc. ( Tran. by YUE Yang) 甲硫醇是蛋氨酸通过酵母代谢的一个重要的中间产物,是二甲基二硫(DMDS)和DMTS等的前体。
A series of supported Mo-based catalysts for methanethiol synthesis from high H 2S-containing syngas were investigated by kinetics and XPS, ESR characterization. 研究了一系列负载型钼基催化剂催化含高硫化氢合成气制甲硫醇的性能,用XPS和ESR对其进行表征。
Methanethiol and disulfide dimethyl were main volatile components and no sulfureted hydrogen was detected under the experimental conditions. 甲硫醇和二甲基二硫醚是主要挥发性含硫化合物,未检测出硫化氢的存在。
Formaldehyde and methanethiol may be generated from Dimethylsulfoxide in acidic condition. 利用二甲基亚砜在酸性条件下可能分解产生甲醛和甲基硫醇。
