WebA continuous process for production of glycerol carbonate esters via a double transesterification is taught by Wetfechtel in US 2007/0299267 and US 2008/0255373. Triacetin is used as the source of glycerin. Glycerin carbonate acetate is formed by the transesterification of triacetin with dimethyl carbonate. WebSep 24, 2024 · Abstract Transesterification of glycerol with dimethyl carbonate to produce glycerol carbonate was studied under continuous reaction over Fe–La mixed oxide catalysts. A series of Fe–La oxide catalysts with different molar compositions were synthesized by co-precipitation method. Surface and structural investigations of the …
