前言乙基伐灭磷的化学名称是O,O-二乙基-O-[4-N,N-二甲氨基磺酰苯基]硫代磷酸酯。原系杀线虫的农药。国外在70年代报导它具有激素性质,对禾谷类、块茎类作物有促进生长作用。1976年我们合成该药,并进行了田间小区试验,取得一定的增产效果。同时,我们还进行了多项生理测定,探明乙基伐灭磷对水稻的生长发育和新陈代谢过程的作用。一、乙基伐灭磷的合成我们根据原料易得,工艺精简,有利生产的原则,采用以下合成路线:并对下述问题作了探讨和改进。 The chemical name of ethylvulphate is O, O-diethyl-O- [4-N, N-dimethylaminosulphonylphenyl] phosphorothioate. The original line to kill nematode pesticides. Abroad in the 70’s reported that it has a hormone nature of cereal, tuber crops have the role of promoting growth. In 1976, we synthesized the drug and conducted a field plot test to achieve a certain increase in yield. At the same time, we also conducted a number of physiological assays to elucidate the role of ethyl ethephon on the growth and metabolism of rice. First, the synthesis of ethyl vincaphaphy We based on raw materials readily available, streamlined technology, the principle of favorable production, the following synthetic route: and the following problems were discussed and improved.
