THERMOCHEMICAL DESTRUCTION OF ESTERS OF 2-CHLORO-2-(1-CYCLOHEXENYL) ETHYLENYLPHOSPHONIC ACID AND THEIR INHIBITORY PROPERTIES

The thermal decomposition of four dialkyl esters of 2-chloro-2-(1-cycl ohexenyl) ethylenylphosphonic acid has been investigated from room tem perature to 600 degrees C. This thermochemical decomposition proceeds as a three-step process. Independently of the thermal changes, the inv estigated esters inhibit the auto-oxidation process of cumene at 110 d egrees C. We followed the formation of the complexes of dibutyl ester and cumyl hydroperoxide, as a result of proton-donor interactions. The se complexes affect cumyl hydroperoxide decomposition. It was establis hed that the investigated eaters catalysed the decomposition of cumyl hydroperoxide.
