Methyl chloroformate

With the inorganic alkali and the presence of phase transfer catalyst , nine synthetic conditions were studied : reaction time , solvent , temperature , inorganic alkali , catalyst , amount of catalyst , amount of Methyl chloroformate , amount of solvents .

在无机碱和相转移催化剂存在下，考察了反应时间、溶剂、温度、无机碱种类、催化剂种类、催化剂用量、氯甲酸甲酯与碱的用量比和溶剂用量等工艺条件对DMDC收率的影响。

The object product HCDA was synthesized by using methyl malonate and methyl chloroformate as raw materials through four steps .

设计了捕收剂HCDA分子的合成路线，以丙二酸二甲酯和氯甲酸甲酯为原料经多步反应最终得到目标产物HCDA。
