Biomass, mainly composed of lignocellulose and vegetable oil, has been acclaimed as one of the most promising sustainable sources of raw carbon material for the synthesis of transport fuels and value – added chemicals. The catalytic conversion of lignocellulose / vegetable oil and their related derivatives has attracted great attention in biomass valorization.

Many elegant methods including hydrolysis, dehydration, hydrogenation, hydrogenolysis, oxidation, etherification, esterification, amination, aldol condensation, Diels– Alder, Knoevenagel condensation, and acetalization have been developed for the valorization of lignocellulose / vegetable oil derivatives toward value – added chemicals and biofuels.

In particular, acetalization is advocated as an appealing approach in biomass valorization because it serves
