## 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.

✦ Synopsis
Les esters sulfuriques d'aminoalcools sont relativement peu connus. Les diesters n'ont pas encore CtC CtudiCs ; quant aux monoesters, quelques-uns ont Ct6 ddcrits, mais aucune Ctude systkmatique n'en a CtC: publibe.
Le monoester sulfurique de l'iithanolamine (amino-2-6thanol ou colamine) a fait l'objet de nombreuses recherches, B cause de l'intCr&t qu'il prksente comme produit de dbpart pour la synthkse de I'Cthylkne-imine :

## 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.
## Abstract Phosphorylcholine is obtained with a good yield when 1 mole of choline or choline chloride is heated with 0,5 to 0,6 mole of pyrophosphoric acid (or the corresponding amount of polyphosphoric acid) for 20 hours at 150° under reduced pressure.
