| titleOfInvention | The production method of butylene oxide ring |
| abstract | The present invention relates to the production method of a kind of butylene oxide ring, mainly solving prior art, to there is butylene oxide ring selectivity low, the problem that catalyzer work-ing life is short. The present invention comprises step by adopting: a) synthesize hydrogen peroxide cumene oxidation liquid; B) controlling organic acid weight percentage in hydrogen phosphide cumene oxidation solution and be not more than 0.3%, the weight percentage of basic metal or alkaline-earth metal ions is not more than 0.1%, and the weight percentage of water is not more than 0.5%; C) hydrogen phosphide cumene oxidation solution and butylene are under the effect of catalyzer, and under liquid-phase condition, reaction generates butylene oxide ring and alpha, alpha-dimethyl benzyl alcohol; D) alpha, alpha-dimethyl benzyl alcohol generates isopropyl benzene with hydrogen generation hydrogenolysis in the presence of a catalyst; The isopropyl benzene generated is circulated to the technical scheme of step a) as the raw material preparing hydrogen phosphide cumene, solves this problem preferably, can be used for preparing in the industrial production of butylene oxide ring. |
