## Abstract Hydroperoxido butyl oleate was decomposed by heating in excess palmitic acid at 60–120 °C. The decomposition followed the kinetics of a first order reaction with formation of both monomeric and oligomeric secondary products. The proportions of oligomers slightly increased with increasin

Pheophytin was heated with hydroperoxyoleate in the medium of methyl palmitate, methyl oleate or methyl linoleate to 60 "C in inert gas. The rate of pheophytin destruction due mostly to free peroxy radicals generated by hydroperoxide decomposition was proportional to the content of hydroperoxide. Do

## Abstract A general mechanism was proposed for the title reactions which describes the kinetics of hydroperoxide decomposition as well as product accumulation throughout the whole reaction period in an analytical form. The following catalytic steps were included: magnified image where the deactiv
