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.

Semiconductor Phostocatalysis. ZnS-Nanocrystallite-Catalyzed Photooxidation of Organic Compounds

Freshly prepared ZnS (nano-ZnS) suspensions catalyze photooxidation of organic substrates under band-gap irradiation with water as a good electron acceptor, while H2 evolves concomitantly.The organic substrates with hetero atoms or carbon-carbon double bonds (?-bonds), such as triethylamine (TEA), diethylamine (DEA), methanol, ethanol, cyclopentene, cyclohexene, 2-methylfuran, toluene, and ethylbenzene, undergo effective one-hole oxidation.This leads to efficient carbon-carbon bond forming reactions between cumulatively formed radicals at the α-carbon adjacent to the hetero atom or the ?-bond.The photooxidation in the presence of a larger quantity of water results in successive oxidation of the intermediary α-carbon radicals, giving the two-hole oxidation products, e.g., DEA and acetaldehyde from TEA and formaldehyde from methanol.The formation of the intermediary α-carbon radical has been clarified by ESR analysis using 2-propanol as an organic substrate.Semi-empirical molecular orbital calculations suggest that the nano-ZnS-catalyzed photooxidation should be predictable from energetics in the formation of the α-carbon radicals through one-hole oxidation and deprotonation, and from change in the bond order of αC-H bond of the α-carbon cation radicals.
