    摘要: Sulfonated phosphines of the formula ##STR1## in which R is cyclohexyl or alkyl having 1 to 4 carbon atoms, M is hydrogen, alkyl substituted ammonium, aryl substituted-ammonium, monovalent metal, or the chemical equivalent of a polyvalent metal, x is 1, 2, or 3 and n is 0 or 1. These compounds are obtained by sulfonation of the non-sulfonated parent substances with oleum or an anhydrous mixture of sulfuric acid and orthoboric acid.

    摘要: The sulfonation of arylphosphines, which contain at least one aromatic radical which can be sulfonated, is carried out with an anhydrous mixture of sulfuric acid and orthoboric acid. By choosing the appropriate reaction temperature, the process allows selective introduction of the desired number of sulfonic acid radicals into the phosphine molecule and avoids the formation of phosphine oxides. When separating the sulfonation mixture, the orthoboric acid can be separated off together with the sulfuric acid.
