一、精胺——乙酰甲胺磷产业链和主要合成工艺乙酰甲胺磷(Acephate)纯品为白色晶体,溶点为92~93℃,相对密度为1.350g/cm3,分子量183.17,易溶于水、甲醇、丙酮等极性溶剂和二氯甲院、二氯乙院等卤代院烃中,在苯、甲苯、二甲苯中溶解度较小,在醚中溶解度更小,在碱性介质中不稳定,可复配成多种含量不同的乳油。乙酰甲胺磷是一种高效、低毒、低残留的内吸触杀杀虫剂,是甲胺磷的乙酸化衍生物,乙酰甲胺磷对环境污染小,施用后很快被植物和土壤微生物降解,乙酰甲胺磷或其代谢产物很快排出体外,都不会在生物体内积累,因此,具有广阔的 First, the spermine - acephate industry chain and the main synthetic process Acephate Pure (Acephate) is a white crystal, melting point of 92 ~ 93 ℃, the relative density of 1.350g / cm3, molecular weight 183.17, soluble In water, methanol, acetone and other polar solvents and dichloromethane, dichloroethane and other halogenated hospital hydrocarbons in benzene, toluene, xylene less soluble in ether solubility is less, in alkaline medium In the unstable, can be mixed into a variety of different content of EC. Acephate is a highly effective, low toxicity, low residual contagious insecticide, is an acetylated derivative of methamidophos, acephate on the environment pollution is small, after application by plants and soil microorganisms Degradation, acephate or its metabolites quickly excreted, will not accumulate in the body, therefore, has a broad
