The invention relates to a method for producing mixtures of alkylphosphonous acid and dialkylphosphinic acid salts, characterized in that a) a phosphinic acid source (I) is reacted with olefins (II) in the presence of a catalyst A to obtain a mixture of alkylphosphonous acid (III) and dialkylphosphinic acid (IV) or salts or esters thereof, and b) the thus obtained mixture of alkylphosphonous acid (III) and dialkylphosphinic acid (IV) or the salts or esters thereof is reacted with metal compounds of Mg, Ca, Al, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na, K and/or a protonated nitrogen base to obtain the corresponding mixtures of alkylphosphonous acid salt (V) and dialkylphosphinic acid salt (VI) of said metals and/or a nitrogen compound, (V) (VI), wherein Y represents Mg, Ca, AI, Sb, Sn, Ge, Ti, Fe, Zr, Zn, Ce, Bi, Sr, Mn, Li, Na; K and/or a nitrogen compound and n represents ¼, ⅓, ½, 1.
本发明涉及一种生产烷基膦酸和二烷基膦酸盐混合物的方法,其特征在于:a)在催化剂A的存在下,将膦酸源(I)与烯烃(II)反应,得到烷基膦酸(III)和二烷基膦酸(IV)或其盐或酯的混合物;b)将所得的烷基膦酸(III)和二烷基膦酸(IV)或其盐或酯的混合物与Mg、Ca、Al、Sb、Sn、Ge、Ti、Fe、Zr、Zn、Ce、Bi、Sr、Mn、Li、Na、K和/或质子化的氮碱金属化合物反应,得到相应的烷基膦酸盐(V)和二烷基膦酸盐(VI),其中Y代表Mg、Ca、AI、Sb、Sn、Ge、Ti、Fe、Zr、Zn、Ce、Bi、Sr、Mn、Li、Na、K和/或氮化合物,n代表1/4、1/3、1/2、1。
