Sorbic acid has also been shown to be a suitable probe for the analysis of the alkylphosphonic acids and their monoester derivatives (14). A run buffer consisting of 5 mM sorbic acid and 0.1 mM decamethonium bromide, adjusted to pH 6, was used to separate a mixture of eight alkyl alkylphospho-nates. The use of the EOF modifier decamethonium bromide reduced the EOF at pH 6 to enhance the resolution and gave complete separation of the alkylphosphonic acids and their monoester derivatives (e.g. MPA and IMPA) in less than 15 minutes, as shown in Figure 3. 

Mixed phosphonate acid esters can also be prepared from alkylphosphonate monoesters, although here the activation is believed occur at the alcohol.57...
