The autoxidation of aliphatic esters. Part 1. The reactions of tert-butoxyl and cumyloxyl radicals with neopentyl esters
Abstract
Six neopentyl esters have been selected, as models for pentaerythrityl esters used as lubricants, to study the selectivity of hydrogen abstraction by alkoxyl radicals. Kinetic and product data for the reactions of two oxygenated radicals, tert-butoxyl and cumyloxyl, with the six neopentyl esters between 408 and 438 K have been determined. They show that attack by the radicals occurs at the α- and subsequent positions on the
