## Abstract In presence of pyro‐ or polyphosphoric acid at high temperature and low pressure, the aminoalkohols can undergo three types of reaction: (A) Phosphorylation, (B) Simultaneous phosphorylation and condensation, (C) Condensation.
## 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 Some new fluorinated phosphoric esters are described. The rate of hydrolysis of the organic fluorine and of the phosphoric ester bond is studied. The phosphoric ester group has a stabilizing effect on the fluorine in alkaline medium, whereas the fluorine has a labilizing effect on the p
