Chemical modification of alumina and silica with alkylphosphonic acids and their esters

Alumina and silica were modified with alkylphosphonic acids and diethyl butylphosphonate. The boundaries of hydrolytic stability of the obtained surface-modified materials were determined.

Process for preparing phosphonic acids

A process for preparing phosphonic acids of the structure STR1 wherein R1 is lower alkyl, aryl, cycloalkyl or arylalkyl, and R2 is H, benzyl or STR2 by oxidizing the corresponding phosphonous acid STR3 employing as the oxidizing agent potassium permanganate or sodium periodate.
