It is also used as a dehydrating agent, in the extraction of drugs, in the manufacture of perfumes (particularly in the preparation of artificial musk), in the recrystallization of chemicals, and as a chemical intermediate (e.g., in the manufacture of tert-butyl chloride and in the manufacture of tert-butyl phenol).

MTBE synthesis from tert-butyl alcohol (t-BA) and methanol has been studied using beta zeolites. Increasing the reaction temperature results in an increase of t-BA conversion with concomittant decrease of MTBE selectivity. The t-BA conversion decreases with increasing calcination temperature and alkali metal ion exchange of Hβ zeolite. The catalytic results are correlated with the surface area and the acidity of catalysts.

Ethyl t-butyl ether (ETBE) 2-ethoxy-2-methylpropane) is an alternative to MTBE as an oxygenate to enhance the octane rating of petrol. It is used mainly in Europe, particularly in France. This accounts for over 90% of the world's annual production of ca 3 million tonnes.
