✦ Synopsis
Menthol, unsaturated alcohols, and cyano alcohols are very easily esterified by phosphorous acid and yield the corresponding phosphorous monoesters.
u-Cyano alcohols yield the corresponding carbamidoalkylphosphorous monoesters, whereas p, y , etc. cyano alcohols yield mixtures containing the corresponding cyano and carbamidoalkyl phosphorous monoesters.

## Abstract Phosphorous monoesters of amino alcohols are obtained by heating equimolecular amounts of phosphorous acid and the corresponding amino alcohol at 150–200°, under reduced pressure.
Phosphorous acid does not dehydrate tertiary alcohols at temperatures below 100 "C ; but the esterification reaction is very slow and phosphorous monoesters of tertiary alcohols cannot be obtained this way. Although this reaction is also slow with phenol, phenyl phosphorous monoester can be obtained

## Abstract Amino alcohols containing a primary, a secondary or a tertiary amino group, yield with phenylphosphonic oxide the corresponding aminoalkyl phenylphosphonic monoesters.
The rate of hydrolysis of phenylphosphonic monoesters at different pH values (0,4,5 and 14), at 100° and in 0,1M solutions, is studied.
