Abstract

The thermal decomposition of anisole vapor dilute in argon has been studied in a perfectly stirred reactor over the temperature range 850-1000 K and at total pressures of (16-120) × 10-3 atm. Decomposition of anisole takes place principally by the reaction C6H5OCH3→C6H5O+CH3, for which the rate constant k1 was found to be (2.9±1.0) ×1015 exp(-64.0±0.6 kcal mol-1/RT)s-1. Phenoxy radicals thus generated may decompose unimolecularly to cyclopentadienyl radicals and CO or react with methyl radicals to form cresols. Phenol is also an important secondary product. Most of the product oxygen originally contained in anisole is found in phenolic compounds rather than in carbon monoxide.
