## Abstract The synthesis and the rate of scission of some new cyanoalkyl‐phosphoric monoesters are described. In the case of β‐cyanoalkyl‐phosphoric monoesters, the monoester group is no more dephosphorylated in alkaline medium when the two H in the β position are substituted by alkyl groups.

Abstract
Tetracoordinated acids of phosphorus (acids of type A) where the P atom is bonded to 4 O, or to 3 O and 1 C, are not esterificd when heated with alcohols.

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 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.
0‐, __m__‐ and __p__‐sulfophenylphosphoric acids have been prepared from PC1~5~ and the corresponding phenolsulfonic acids. The rates of hydrolysis of these phosphoric esters at pH 0 (HCl 1N), 4,5 and 14 (NaOH 1N) and at 100° have been established.
