Amino-phosphonates are prepared by reacting an enamine with a phosphite ester, for example, according to the equation ##STR1## where OR' is an alcohol moiety and NR.sub.2 is an amino moiety, both R and R' being preferably hydrocarbon such as alkyl or R.sub.2 is part of a ring structure. These compounds have many uses, for example, as corrosion inhibitors, scale inhibitors, fuel stabilizers, etc. In addition, amino-phosphonates can be converted to alpha, beta - unsaturated phosphonates according to the equation ##STR2## which are useful in forming flame retardant polymers and copolymers.
氨基膦酸盐是通过将烯胺与亚磷酸酯反应制备的,例如,根据以下方程式进行反应:其中OR'是醇基团,NR.sub.2是氨基团,R和R'通常为烃基,如烷基,或R.sub.2是环结构的一部分。这些化合物有许多用途,例如作为防腐剂、阻垢剂、燃料稳定剂等。此外,氨基膦酸盐可以根据以下方程式转化为α,β-不饱和膦酸盐,这对于形成阻燃聚合物和共聚物是有用的。
