乙酰甲胺磷制备

1、生产乙酰甲胺磷的原料有甲基氯化物、氨水、二氯乙烷、乙酐、硫酸二甲酯。通过胺化、酰化、异构化等反应步骤而得。1.胺化将甲基氯化物及相应比例量的二氯乙烷分别从高位计量槽加入胺化釜中，开启搅拌和冷冻盐水，当釜内温度降至15℃时，由氨水高位计量槽慢慢滴加氨水于釜中，釜中温度控制在35-40℃，保持35-40min，滴加氨水完毕后，调节冷冻盐水，使釜内温度降至20-23℃。保持温度搅拌30-35min，然后加入6L水，搅拌2-3min后，停止搅拌，将物料抽至胺化分离器中静置分层，30min后，将有机相放至受槽计量，该有机相即为带溶剂的胺化物（O,O-二甲基硫代磷酰胺）。2.酰化（1）乙酐法将带溶剂的胺化物由高位计量槽放入酰化釜中，开启搅拌，再由乙酐高位计量槽加入乙酐于酰化釜中，再开启冷冻盐水，使釜中温度降至10℃时，将浓硫酸从高位计量槽慢慢地滴加进反应釜中，滴加硫酸完后，开启空压，将夹套中的冷冻盐水排出，用蒸汽慢慢加热，使釜中温度升至55-60℃，保持50min，反应完毕，再将釜内温度降至10℃，由氨水高位槽滴加氯水，以中和反应生成的乙酸，中和至pH值7-8，在中和过程中，温度应控制在30℃以下，中和完后，将物料抽至分离器中静置分离，分出下层有机相至粗酰化物贮槽，再抽进蒸馏釜中进行减压蒸馏脱溶（真空度86.7kPa，70℃、15-20min），即得酰化物（O,O-二甲基-N-乙酰基硫代磷酰胺）。（2）乙酰氯法将带溶剂的胺化物由高位计量槽放入酰化釜中，开启搅拌，从乙酰氯高位计量槽加入乙酰氯。然后慢慢将釜中温度升至50℃，保持温度反应2h，反应毕，将反应釜内温度降至10℃，然后由氨水高位计量槽慢慢滴加氨水，以中和反应生成的酸，中和至pH值7，在中和过程中，釜内温度应控制在30℃以下，中和完毕后，加入适量的水。以溶解中和过程中生成的铵盐，搅拌2-3min，将物料抽至分离器静置分离。分出下层有机相，抽至蒸馏釜中减压脱溶（真空度86.7kPa，70℃、15-20min），即得酰化物。酰化反应采用乙酐或乙酰氯为酰化剂都能取得较好的结果。3.异构化从酰化物高位计量槽将定量的酰化物放入异构化釜中，开启搅拌，随后由硫酸二甲酯高位计量槽按比例将硫酸二甲酯加入异构化釜中，慢慢升温至65-70℃，保持温度2h，出料，即得乙酰甲胺磷原油。每生产1t50%浓度的原油，消耗原料：甲醇（98%）1953kg、三氯化磷（98%）1660kg、烧碱（30%）3220kg、硫酸二甲酯（98%）120kg、氨水（18%）2450kg、硫磺（98%）315kg、乙酸（98%）295kg、胺化物（40%）1700kg、乙酐（69%）490kg、硫化铵（工业品）2200kg、二氯乙烷（98%）250kg。

2、先异构化后酰化先将O，O-二甲基硫代膦酰胺在少量硫酸二甲酯存在下，加热异构化，生成O，S-二甲基硫代膦酰胺，然后与乙酐或乙酰氯作用，生成乙酰甲胺磷。
先酰化后异构化先将O，O-二甲基硫代膦酰胺在二氯乙烷或苯溶剂中与酰化剂反应，常用的酰化剂有冰醋酸+三氯化锌、醋酐、乙酰氯、乙烯酮等。酰化反应生成O，O-二甲基-N-乙酰基硫代膦酰胺，然后在少量硫酸二甲酯存在下，加热异构化为乙酰甲胺磷。
采用新型催化剂和特殊的结晶溶剂，可制得高纯度原药，工艺过程是：在反应瓶中加入甲胺磷原油200g，开启搅拌加热至反应温度，在催化剂的作用下，滴加酰化剂醋酐，控制反应温度，滴加完毕进行保温反应数小时，即得乙酰甲胺磷粗原油；再经中和、萃取分出有机相和水相，有机相提纯得乙酰甲胺磷精原油；加入溶剂A和晶形助剂，缓慢搅拌冷却结晶、过滤、漂洗后得成品。所得母液处理后可回收合格的成品，合计产品总收率>78%，含量≥98.0%。

3.以甲基氯化物、氨水、二氯乙烷、乙酐、硫酸二甲酯为原料。通过胺化、酰化、异构化等反应制得乙酰甲胺磷。即胺化得到犗犗二甲基硫代磷酰胺，经酰化得酰化物犗犗二甲基犖乙酰基硫代磷酰胺，再经异构化反应得到乙酰甲胺磷。
