Preparation method of 4,5-epoxytetrahydrophthalate glycidyl ester

The present invention provides a method for preparing 4,5-epoxytetrahydrophthalate glycidyl ester. The present invention by taking acetic anhydride as raw material, adding 62.5% ~ 64.7% of hydrogen peroxide and a certain amount of acidic catalyst oxidation to generate peracetic acid, and then the tetrahydrophthalic acid glycidyl ester and the reaction of peracetic acid to obtain epoxy reaction, and then through a series of post-treatments to give 4,5-epoxytetrahydrophthalic acid glycidyl ester. The preparation method of the present invention is compared with the traditional process, which greatly reduces the concentration of hydrogen peroxide, thereby solving the problem that high concentration of hydrogen peroxide in the traditional process is easy to explode during storage, transportation and use, and also reduces the cost of raw materials. Compared with the prior art, the epoxy value of 4,5-epoxytetrahydrothphthalate glycidyl ester products prepared by the present invention is also higher.
