摘要
以二烷基亚磷酸酯、顺丁烯二酸二烷酯,以及丙烯酸烷酯等为原料,在强碱性催化条件下,经 一步连续反应合成PBTCA(2\|膦酸基\|1,2,4三羧酸丁烷),产率为87.7%；采用IR、 31P-NMR、1H-NMR、13C-NMR等方法证实了合成产物的分子结构,并 取得了理想的结果.
In alkali catalytic condition, PBTCA (2-phosphono-1,2,4-tricarboxylic acid butane) is prepared from dialkyl-phosphite ester, maleic acid dialkylester and alkylacrylic easter by one-step successive reaction, its yield is 87.7%. The mole cular structure of PBTCA is examined by IR, 31P-NMR,1H-NMR, 13C-NMR spectroscopy methods and ideal result is obtained
