General description

tert-Butanol is a tertiary alcohol. Aqueous potassium peroxodisulfate undergoes photolysis in the presence of tert-butanol on irradiation with 254nm light at 20°C to afford hydrogen sulfate.

Application

tert-Butanol may be employed for the preparation of carbohydrate fatty acid esters. It may be employed as a reaction medium during the production of fatty acid methyl ester (FAME) from waste cooking palm oil (WCPO) by lipase-catalyzed reaction.

It can be used for the butylation of p-cresol in the presence of 12-tungstophosphoric acid supported on zirconia catalyst. 2-tert-Butyl-p-cresol (TBC), 2,6-di-tert-butyl-p-cresol (DTBC) and tert-butyl-p-tolyl ether (ether) are formed as butylation reaction products.
