乐果制备
1.工业上生产乐果的方法主要有氯乙酰甲胺法、后胺解法。后一种方法是在氯乙酰甲胺法之后发展起来的,此法副反应少,产品纯度可达90%以上,粗品收率90%左右。
2.O,O一二甲基二硫代磷酸(简称甲基硫化物)的制备通常采用P2S5与CH3OH作用,甲醉适当过量,反应温度55-60 ℃,为强放热反应,操作时要特别注意安全。反应过程较复杂,同时发生一系列副反应。O,O一二甲基二硫代磷酸的收率和含量75 %-80 %采用适当催化剂,在(55士2)℃反应,收率和含量可达90℃左右。
3.O,O一二甲基一5-(乙酸甲酷)二硫代磷酸酷的制备O,O一二甲基一S(乙酸甲酷)二硫代磷酸酷由O,O一二甲基二硫代磷酸钠与氯乙酸甲酷作用制得,原料配比为1:1.7,反应温度55℃,若采用连续化生产工艺,预热温度h0一70 ℃,反应温度X80士5)℃。
4.乐果的合成O,O一二甲基一S-(乙酸甲酯)二硫代磷酸a与一甲胺作用,原料配比为1:(1.2-1.3),反应温度一5一0 ℃反应结束加苯(或二氯乙烯)萃取反应液中乐果,加盐酸调竹pH值为7,加适量水,以促进分层。规格40 %, 50 %, 80 %,乐果乳油;4%,蚕用乐果乳油;3.6%}高渗乐果乳油;2 % , 3% , 10 %,乐果剂;20 %, 50 %,乐果可湿性粉剂;10 %, 50%乐果颗粒剂。
