Abstract
Poly‐cyclohexanephosphonic acid is obtained very easily by heating cyclohexanephosphonic acid, under reduced pressure, at 180–190°C, for 96 to 150 hours.

## Abstract Amino alcohols containing a primary, a secondary or a tertiary amino group, yield with phenylphosphonic oxide the corresponding aminoalkyl phenylphosphonic monoesters.
## 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.
