    • The invention relates to a process for separating a mixture containing phosphoric acid monoalkylesters, phosphoric acid dialkylesters and minor proportions of diphosphoric acid dialkylesters, each with 6 to 12 carbon atoms in the alkyl radical, by extractively distributing them between an aliphatic or aromatic hydrocarbon as an unpolar solvent and a polar solvent. To this end, the invention provides: for the ester mixture to be admixed with the quantity of water stoichiometrically necessary for hydrolyzing the P-O-P-bond of the diphosphoric acid dialkylester with the resultant formation of the phosphoric acid monoalkylester; for the whole to be maintained for at least 1 hour at temperatures higher than 60.degree. C.; for the partially hydrolyzed ester mixture to be treated in a countercurrent apparatus comprising n-stages with the solvents immiscible or partially miscible with one another so as to ensure introduction of pure solvent into stage 1 and stage n, respectively, and the introduction of partially hydrolyzed mixture into one of the stages 2 to (n-1), n standing for a whole number of at least 3.
    • 本发明涉及一种在烷基中分离含有磷酸单烷基酯,磷酸二烷基酯和较少比例的二磷酸二烷基酯的混合物的方法,它们各自具有6至12个碳原子,通过将其分散在脂族或芳族烃之间,作为 非极性溶剂和极性溶剂。 为此,本发明提供:将酯混合物与水解磷酸二烷基酯的P-O-P键的化学计量所需的水量混合,从而形成磷酸单烷基酯; 整体在高于60℃的温度下保持至少1小时。 对于部分水解的酯混合物在包含n阶段的逆流装置中进行处理,其中溶剂与溶剂彼此不混溶或部分混溶,以确保将纯溶剂分别引入阶段1和阶段n,并引入部分水解的 混合物进入阶段2至(n-1)之一,n代表至少3的整数。
