酚的氧化实验是大学有机化学实验中的一个重要验证性实验［1］［2］。常用的方法是将对苯二酚即氢醌固体配成溶液后，用碱性高锰酸钾或酸性重铬酸钾溶液为氧化剂，最终出现暗绿色针状晶体。针状晶体为氢醒的氧化产物对苯配和溶液中氢醒的组合物。此实验现象不易出现，中间也存
Phenol oxidation experiments in the university organic chemistry experiment is an important confirmatory experiment [1] [2]. Commonly used method is hydroquinone hydroquinone solid dubbed the solution, the use of alkaline potassium permanganate or acid dichromate solution as the oxidant, the final appearance of dark green acicular crystals. The acicular crystal is a hydrogen-waking oxidation product that reacts with the hydrogen in the benzene-complexed solution. This experimental phenomenon is not easy to appear, the middle also exist
