Abstract

Kinetics of the chlorination and bromination of jojoba oil has been studied at different temperatures, solvents, and operating conditions. Chlorination follows first-order kinetics in double bond concentration with an activation energy
of -11 kcal/mol. Solvents with high dielectric constant increase the rate of reaction. Bromination involves a two-step mechanism with one or two bromine molecules per double bond; up to 0.2 s reaction time the rate is first order
in each of the reagents, and afterwards it is first order in the double bonds and second order in bromine. Faster rates are obtained lowering the temperature and/or increasing the dielectric content of the solvent. The chlorinated
derivative improves the load carrying capacity of the lubricating oil
