The mechanism of ester formation and the reactions of acids in processes of liquid-phase oxidation of hydrocarbons

Summary
- 1.
Capric acid undergoes oxidation with the elimination of CO2 in a medium of octadecane which is being oxidized. Oxidation of the acid proceeds to a definite limit, depending on the temperature. Semilogarithmic representations of the kinetic curves of acid oxidation, allowing for the limiting extent of oxidation, are straight lines whose slope is independent of temperature.
- 2.
The limited character of capric acid oxidation indicates the presence of a reaction-retarding process, which develops during the oxidation of octadecane. This retardation may be connected with shortening of the oxidation chains and a decrease in the rate of active center generation.
- 3.
The rate of esterification of capric acid during octadecane oxidation was studied. Analysis of the data obtained showed that the bulk of the esters was not formed as a result of esterification of acids by alcohols.
