Environment-friendly synthesis method for 2,3,5-trimethyl hydroquinone

The invention relates to the field of chemical pharmacy, and in particular relates to an environment-friendly synthesis method for 2,3,5-trimethyl hydroquinone. The environment-friendly synthesis method for 2,3,5-trimethyl hydroquinone comprises the following steps: dissolving 1,2,4-trimethylbenzene serving as a raw material by using an organic solvent; adding hydrogen peroxide oxidant to oxidize 1,2,4-trimethylbenzene into 2,3,5-trimethyl p-benzoquinone to obtain a synthetic product; extracting the synthetic product to obtain an extract liquid; adding a reducing agent into the extract liquid; heating to perform a reduction reaction to synthesize 2,3,5-trimethyl hydroquinone. 1,2,4-trimethylbenzene serving as the raw material used in the synthesis method is inexpensive and easy to get; the used reaction reagents, for example, hydrogen peroxide, the organic solvent, the extraction agent and the reducing agent, are all commonly used reagents; moreover, the raw materials are low in cost; the used reagents can be recycled; the synthesis method has the advantages of mild reaction conditions, easiness in operation, a short process flow, low causticity on reaction equipment and low pollution to the environment, and is a green and environment-friendly industrial production line.
