Olefins from fatty alcohols are produced by the reaction of α -olefins with water under the action of a catalyst.
α-olefin is an important organic material, can be used to make -olefin synthetic oil (PAO), alkyl benzene can also be produced. The α-olefin of C10-C14 can be used in the production of depressants;
The α-olefins of C14-C18 can produce α-olefins sulfonates (AOS).; α-olefins above C18 can be used directly as lubricant additives and drilling fluids. The α-alkenes can also be synthesized into plasticizers , epoxides, amine or straight-chain mercaptan.
