In a solution that is free of bases and free of oxygen and which contains at least four molar proportions of the reactant tris(hydroxymethyl)phosphine for every three molar proportions of an aralkyl halide reactant, the following reaction produces tris(aralkyl)phosphine product: 3(Ar-CH.sub.2 X) + 4P(CH.sub.2 OH).sub.3 .fwdarw. (Ar-CH.sub.2).sub.3 P + 3P.sup.+ (CH.sub.2 OH).sub.4 X.sup.- after separation of the phosphine product, the phosphonium salt by-products can be converted to tris(hydroxymethyl)phosphine by the addition of a base.
在一个不含碱和氧气的溶液中,每三摩尔的芳基卤化物反应物中至少含有四摩尔的三(羟甲基)膦反应物,以下反应产生三(芳基)膦产物:3(Ar-CH.sub.2 X) + 4P(CH.sub.2 OH).sub.3 .fwdarw. (Ar-CH.sub.2).sub.3 P + 3P.sup.+ (CH.sub.2 OH).sub.4 X.sup.- 分离出膦产物后,膦盐副产物可以通过加入碱转化为三(羟甲基)膦。
