标题:一种甲基亚膦酸酯与草铵膦的合成方法
摘要:本发明公开了一种甲基亚膦酸酯与草铵膦的合成方法.该方法以五硫化二磷为起始原料先经硫化反应,氯化反应,水洗,蒸馏提纯后催化加氢得到氯代亚膦酸酯(Iii),再经格式反应得到甲基亚膦酸酯(Iv),其中r为c1~c4的烷基.该方法以五硫化二磷为起始原料,经硫化反应,氯化反应,水洗,蒸馏提纯后,催化加氢得到氯代亚膦酸酯再经格式反应合成甲基亚膦酸酯,再经现有技术的strecker路线得到最终产物草铵膦,不仅提高了合成收率,同时不会产生甲基二氯化磷等不稳定腐蚀性中间体,减少了三废物质的排放,降低了环保成本和压力.

标题 :Improved process for production of phosphoesters of glufosinate precursors
发明人：LAUTENSCHÃœTZ LUDGER; BRAUNE SASCHA; PÖTTER MARKUS
权利人:EVONIK OPERATIONS GMBH
摘要:SummaryThe present invention relates to a method for production of a compound according to formula (I):wherein R is alkyl, aryl, alkaryl, aralkyl,and wherein X is selected from the following structures (I-A), (I-B):wherein R¹, R² are independently selected from the group consisting of alkyl, aryl, alkaryl, aralkyl.The compounds according to formula (I) are important precursors in the synthesis of glufosinate, in particular L-glufosinate. In the method according to the present invention, easily accessible starting materials are employed. Thus, the method overcomes the disadvantages of prior art syntheses of L-glufosinate and its intermediates.
