专利号:US-5872245-A 优先权日:1992-09-30 标题 :Continuous process for the synthesis of sucrose fatty acid esters 发明人:WILSON DONALD C 权利人:OPTIMA TECHNOLOGIES GROUP 摘要:This present invention pertains to a process for the synthesis of sucrose fatty acid esters by reacting sucrose and a purified specific fatty acid ester under substantially solvent free conditions in the presence of a transesterification stationary catalyst and mechanical emulsification. The process is continuous, yielding selected individual products of separated simple sucrose fatty acid esters of mono-, di-, tri- and polyesters while recycling the unwanted ester fractions, the unreacted sucrose and fatty acid ester.

专利号:WO-2025018894-A1 优先权日:2023-07-19 标 题:Bio-renewable surfactants based on fructose and fatty acid esters. 发明人:MINNAARD ADRIAAN JACOBUS; LIN HUNG-CHIEN; FRIDRICH BÃ?LINT 权利人:UNIV GRONINGEN 摘要:The invention relates to the fields of surfactants and green chemistry, more in particular to means and methods for the synthesis of novel surfactants based on readily available and biorenewable building blocks. Provided is a method for the synthesis of a carbohydrate surfactant molecule, comprising the steps of: (i) reacting a fructose-containing saccharide with 3-hydroxy propionitrile under acid conditions to obtain the cyano-intermediate compound cyanoethyl β-fructopyranoside; (ii) hydrogenating the cyano-intermediate compound in the presence of a catalyst to obtain an amine-intermediate compound; and (iii) amidating said amine moiety by contacting the amine-intermediate compound with at least one alkyl ester or glycerol ester of a saturated or unsaturated, optionally substituted, aliphatic C4-C22 carboxylic acid in the presence of a base to obtain a fructose-based surfactant molecule.
