| titleOfInvention | Formation of sugar esters from vinyl fatty acid esters |
| abstract | A sugar ester product is produced from sugar and vinyl fatty acid. The sugar is first dissolved in dimethyl sulfoxide with a metal carbonate catalyst. Vinyl fatty acid esters are mixed into the sugar mixture; a sugar ester product and acetaldehyde are formed. Vacuum is used to remove acetaldehyde and the reaction is complete. Depending on the sugar relative to the proportion of vinyl fatty acid ester, some yield a reaction yield of over 90% with a monoester content of 90%. DMSO is then recovered by vacuum distillation. The crude product is dissolved in brine; sucrose stearate is extracted by adding isobutanol along with vinyl stearate and a small amount of sucrose. The isobutanol phase is separated from the aqueous phase and concentrated. Spray drying is performed to remove the remaining solvent and vinyl stearate. The product is a white powder and meets FDA standards for sucrose esters. |
