PROCESS FOR PREPARING ADIPIC ACID

摘要

In a process for preparing adipic acid from cyclohexene oxide, cyclohexene oxide is hydrated to prepare 1,2-dihydroxycyclohexane and oligomers represented by formula (I): (see formula I) wherein n represents a number of from 1 to 5, and then a mixture comprising the oligomer represented by formula (I) and/or 1,2-dihydroxycyclohexane and/or cyclohexene oxide is oxidized in a nitric acid aqueous solution to prepare the adipic acid with industrial advantages.
