Abstract
Selective acetalization of furfural and 5-hydroxymethylfurfural by methanol in the presence of silica catalysts was investigated. Catalytic activity of silica materials (MCM-41, SBA-15, and silicagel) in reaction of furfural and 5-hydroxymethylfurfural acetalization by methanol was brought into correlation with its structure and textural properties. Mesostructured silica materials (MCM-41, SBA-15) allow obtaining of furfural and 5-hydroxymethylfurfural methylacetals with the 80-95% yield and up to 98% selectivity.
