Descrizione

Descrizione generale

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.

Applicazioni

• Synthesis of Ribose - Oleic Acid Esters in the Presence- and Absence of Candida antarctica Lipase B.: This study investigates the synthesis of ribose-oleic acid esters using tert-Butanol as a solvent, both with and without the presence of Candida antarctica Lipase B. The research explores the efficiency and effectiveness of the enzyme-catalyzed process, highlighting the impact of tert-Butanol on the synthesis reaction. The findings contribute to the understanding of esterification processes in analytical chemistry and have potential applications in developing new synthetic methods (Çetinkaya et al., 2020).
