MTBE and TAME Synthesis

A third class of RD processes that are known to show intricate nonlinear behavior, are processes for the production of fuel ethers methyl tert-butyl ether (MTBE) and tert-amyl methyl ether (TAME). These are produced by etherification of iso-olefins with methanol according to iso-olefin + methanol ^ tert-ether (10.2)

The reactions are catalyzed by strong acid ion-exchange resins and are usually carried out in the presence of inert components. For MTBE synthesis the iso-olefin is isobutylene and for TAME synthesis the iso-olefins are 2-methyl-1-butene and 2-methyl-2-butene. Further details on the chemistry of etherification processes are given in Chapter 5.
