摘　　要：苯二酚有邻苯二酚、间苯二酚、对苯二酚3种同分异构体。3种同分异构体在工业生产中均具有非常广泛的应用。现有苯二酚生产工艺为苯酚羟基化法,产物苯酚羟化液含水高,分离精制能耗极高。作者研究了新型热耦合节能工艺,年操作费用节约48%,具有广阔的市场前景。Hydroquinone has three isomers:catechol,resorcinol,and hydroquinone.The three isomers have a very wide range of applications in industrial production.The current direct oxidation process of phenol is problematic because high-concentration hydrogen peroxide is prone to explosion,while low-concentration hydrogen peroxide leads to high production costs.This article studies a new thermo-coupled energy-saving process,reducing 48%of annual operating cost,which has broad market significance.
