The Improvement on Synthetic Methods of Dihalogeno-1,4-benzoquinones
The synthetic methods of 2-bromo-, 2,5-dibromo-1,4-hydroquinone(1,3), 2,5-dibromo-, 2,5-dichloro-, 2,3-dichloro-1,4-benzoquiones(4.6,8) was improved. The much easier and more efficient methods were discussed. Also. "one pot" method of synthesizing 2, 5-dichloroquinone(6) was put forward. It has hydrochloric acid adding to quinone and oxidated by nitric acid at the same time.
