Preparation of hydroquinone fromp-benzoquinone intensified by reduction with iron powder under electric field
摘要
Abstract
Preparation of hydroquinone fromp-benzoquinone intensified by reduction with iron powder was studied under electric field in the acidic system. The effects of dosage of iron powder,dosage of H2SO4,means of adding H2SO4,voltage and reaction time on the utilization ratio of iron powder and the yield of hydroquinone were investigated and the mechanism of the reaction process was studied. Electric field strengthened the electronic directional migration and activated iron powder in the reduction process.Optimal parameters were obtained with molar ratio of H2SO4/Fe 1:3 at 3.0V for 2h,and H2SO4 was added gradually. The utilization ratio of iron powder was increased from 28.57% to 75.19% and the yield of hydroquinone was up to 95%. Compared with the present industrial process, there was higher iron powder utilization and there was no reduction byproduct. Furthermore,the method was easy to control and could greatly shorten the reaction period.关键词
