Abstract Isobutylene is one of the important basic organic chemical raw materials, a monomer synthetic rubber and is mainly used for the preparation of butyl rubber and poly-isobutylene; high purity isobutene can be used for the production of butyl rubber, poly-isobutylene, tert-butyl phenol, antioxidant, butyl amine, methyl propylene nitrile and many other organic chemical raw materials and fine chemical industry products. No matter is the preparation of butyl rubber or poly-isobutylene, require the high purity isobutene. Tert-butyl alcohol by dehydration reaction can obtain high purity isobutene. If used as a fine chemical raw material, then its value is higher. Since the world developed country requirements for clean gasoline increases, the amount of TBA also get rapid growth. This makes the supply and demand will tend to be nervous of isobutene. At the same time, as the world continues to accelerate the development of high value-added fine chemical products, for the fine chemical raw materials of pure isobutylene demand increases. This paper study on the dehydration of butyl alcohol is for preparing isobutene process calculation.
