94%无臭马拉硫磷原油合成新工艺

New process of synthesis tasteless 94% crude oil malathion

经过反复试验,研制出了采用化学提纯法提高中间体硫化物的质量,采用水蒸气蒸馏法脱除过量的二乙酯,采用化学氧化法脱除臭气制备94%无臭马拉硫磷原油的新工艺。

By experiment again and again, new process of synthesis tasteless 94% crude oil malathion was researched. That key technique is: the technique of chemical parification was adopted in order to improve the quality of sulfide, the technique of steam distillation was adopted in order to remove overdosage diethyl ester, the technique of chemical oxidation was adopted in order to remove off flavour.
