✦ Synopsis


Abstract

The action of polyphosphoric and orthophosphoric acids on glycols and hydroxy‐ethers is described. Apart the phosphorylation of these compounds, some of the side reactions which may occur (etherification of the hydroxy‐compound, scission of the hydroxy‐ether, etc.) are studied.

## Abstract The phosphorylation of hydroxy groups by polyphosphoric acids is shown to be inhibited by carboxyl functions, but the phosphorylation of hydroxy acids can be realized by using their esters, amides or nitriles; the phosphorylated derivatives obtained yield the phosphohydroxy acids either

## Abstract 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%) a

The reaction of phenylphosphonic oxide with amines and amino‐alcools is described. Under appropriate conditions this reaction yields respectively the corresponding phosphonic mono‐amides and mono‐esters.
