The synthesis of cyclic phosphoric esters with 5, 6 and 7 membered rings by cyclisation of hydroxy- or chloro-alkyl phosphoric acids or by direct phosphorylation of the corresponding diols or chloro-alcohols is described. The 6 membered cyclic esters are the easiest to obtain.

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.
