Abstract

The apparent activation energy for the synthesis reaction of methyl tert-butyl ether or MTBE, was found to be 64 KJ/mole. The best activity and selectivity for MTBE were observed at temperatures of 85 - 90 °C, and contact times of circa 2.5 h when the methanol / isobutene molar ratio was kept within the 1.2 - 1.5 range. There was a fierce competition between the ethyl tert-butyl ether formation and that of diethylether at reaction temperatures higher than 85 °C.
