Title:
METHOD FOR PREPARING ADAMANTANE
Document Type and Number:
WIPO Patent Application WO/2024/001986
Kind Code:
A1
Abstract:
Disclosed is a continuous method for producing adamantane, comprising the following steps: 1) providing a liquid feed stream comprising endo-tetrahydrodicyclopentadiene; and 2) enabling the liquid feed stream to sequentially pass through a first reaction zone filled with a hydrogenation protective agent and a second reaction zone filled with an isomerization catalyst to carry out a hydroisomerization reaction to obtain adamantane. The method is simple in process operation and free of pollution, can realize long-period continuous preparation for adamantane, and has an actual industrial application prospect.
