| General description: | tert-Butanol (tBA) is a tertiary alcohol. It undergoes dehydration by reactive distillation in the presence of solid acid catalyst to form isobutylene with high selectivity. Lipase-mediated alcoholysis of soybean oil deodorizer distillate (SODD) has been conducted in tBA (as reaction medium) to generate biodiesel. Formation of 2-tert-butyl-p-cresol (TBC), 2,6-di-tert-butyl-p-cresol (DTBC) and tert-butyl-p-tolyl ether has been reported when p-cresol undergoes butylation by tBA in the presence of 12-tungstophosphoric acid supported on zirconia (TPA/ZrO2) catalyst. The interaction behavior of tBA on the Si (001)-(2×1) surface has been assessed by using the ab-initio density functional theory (DFT) based on pseudopotential approach. |
