The authors describe the isolation of cyclic phosphoric esters from the complex mixture produced by the treatment of certain glycols with polyphosphoric acid, mixture which contains in larger amounts hydroxyalkylphosphoric esters. In this way, trimethylenephosphoric acid (yield 15,8%) and tetramethylenephosphoric acid (yield 0,3%) are easily obtained from the corresponding glycols.
作者描述了从通过用多磷酸处理某些二醇而产生的复杂混合物中分离环状磷酸酯,该混合物含有大量的羟烷基磷酸酯。这样,可以容易地从相应的二醇获得三亚甲基磷酸(产率15.8%)和四亚甲基磷酸(产率0.3%)。
