The present invention is related to a method for the synthesis of an aminoalkylenephosphonic acid or its phosphonate esters comprising the following steps: a) forming, in the presence of an aldehyde or ketone and an acid catalyst, a reaction mixture by mixing a compound comprising at least one HNR1R2 moiety or a salt thereof, with a compound having one or more P-O-P anhydride moieties, said moieties comprising one P atom at the oxidation state (+III) and one P atom at the oxidation state (+III) or (+V), wherein the ratio of moles of aldehyde or ketone to N-H moieties is 1 or more and wherein the ratio of N-H moieties to P-O-P anhydride moieties is 0.3 or more and, b) recovering the resulting aminoalkylenephosphonic acid comprising compound or its phosphonate esters.
本发明涉及一种合成氨基烯膦酸或其膦酸酯的方法,包括以下步骤:a) 在醛或酮和酸催化剂的存在下,通过将至少含有一个HNR1R2基团或其盐的化合物与至少含有一个或多个P-O-P酸酐基团的化合物混合形成反应混合物,所述基团包括一个氧化态为(+III)的P原子和一个氧化态为(+III)或(+V)的P原子,其中醛或酮的摩尔比与N-H基团的比值为1或更多,N-H基团与P-O-P酸酐基团的比值为0.3或更多;b) 回收所得的氨基烯膦酸化合物或其膦酸酯。
