摘要
采用多种核磁共振(NMR)技术测定了工业氨基三甲叉膦酸(ATMP)产品中副产物的分子结构 ,发现该物质为甲氨基二甲叉膦酸(MADMP) ,它是甲醛歧化反应导致的副产物 ;给出了可能的反应方程式 ;测出了MADMP的相对含量 ,MADMP与ATMP摩尔比约为2。
The molecular structure of a by _ product in industrial amino tri(methylene phosphonic acid)(ATMP) sample was determined by using diverse NMR techniques. It has been found that the main by _ product is methyl _ amino di(methylene phosphonic acid)(MADMP), which comes from formaldehyde disproportionation. The possible reaction equation and the relative content of MADMP were given. The mole ratio of MADMP to ATMP in the analyzed sample was about 2.
