## Abstract Hydroxy nitriles when treated with polyphosphoric acid yield the corresponding carbamido‐alkyl phosphoric acids; but when treated with POCl~3~ in the presence of a tertiary base they yield the corresponding cyano‐alkyl phosphoric acids. β‐cyanoethyl phosphoric acid is very easily dephos
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.
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.
