Preparation method of high-heat-resistance diepoxide

The invention discloses a preparation method of a high-heat-resistance diepoxide. The preparation method comprises the following steps: in the presence of 4-toluenesulfonyl chloride and pyridine, reacting 4, 4'- dihydroxydicyclohexane with a metal halide; then carrying out dehalogenation in an alkaline environment to prepare [1, 1' -bis(cyclohexane)]-3, 3' -diene; or in the presence of thiourea, 4, 4apos;-dihydroxy dicyclohexane is subjected to a reaction with halogenated succinimide; then carrying out dehalogenation in an alkaline environment to prepare [1, 1'-bis(cyclohexane)]-3, 3'-diene; and then reacting the[1, 1'-bis(cyclohexane)]-3, 3'-diene with peroxyacetic acid to produce the diepoxide. An existing method has the technical defects of high energy consumption, poor selectivity and the like, isomers exist when a hydroxyl group is dehydrated in a strongly acidic environment, rectification purification is needed, and the product yield is low, and based on the problems, technical innovation is carried out, the hydroxyl group is halogenated firstly, then double bonds are formed in a strongly alkaline environment, post-treatment steps are simplified, and especially, the existence of an isomer is avoided, and the (3, 4, 3 ', 4'-diepoxy)bicyclohexane can be efficiently and conveniently prepared.
