Low-temperature oxidation of anisole and benzyl alcohol by model compounds of coal spontaneous combustion
Abstract：According to the coal spontaneous combustion theory and chemical structure of coal,the anisole and benzyl alcohol were adopted as the model compound.Authors researched the oxidation of methoxy and hydroxymethyl in model compounds from 20 ℃ to 130 ℃.Oxidation products of model compound were measured at different temperatures by programmed heating.Oxidation properties of the model compound at different temperatures were analyzed by chromatographic.The results show that the oxidations of anisole and benzyl alcohol generate carbon monoxide,carbon dioxide,benzene and phenol.The oxidation activity of methoxy is weak before 50 ℃ and then gradually goes up with temperature increased,but the rate increase slowly.In contrast,the oxidation activity of hydroxymethyl in benzyl alcohol is weak before 70 ℃.However,the oxidation activity of active group in benzyl alcohol increases once the temperature climbes to 70 ℃.Especially,when the temperature reaches 120 ℃,the oxidation activity of hydroxymethyl in benzyl alcohol dramatically grows.
