The invention discloses a method for jointly preparing dicyclopentadiene dioxide and alkylene oxide by using titanium-silicon molecular sieve catalyst. The olefin with carbon number of 3-10 is added to the reaction product, and the excess organic peroxide and the olefin continue to react to generate alkylene oxide, thereby effectively removing the organic peroxide in the reaction product. The preparation method is used for the synthesis of dicyclopentadiene dioxide, which not only has high conversion rate of DCPD, high product selectivity, simple process operation, but also can synthesize alkylene oxide, and the organic peroxide in the reactant is fully utilized to effectively solve the reaction problem. The problem of separation of organic peroxides in the product also provides a green reaction process for the synthesis of alkylene oxides. |
