Title: | Process for the selective preparation of derivates of monosacchariddes and polyols wihc ar partially acylated. |
Other Titles: | Proceso selectivo para la preparación de derivados de monosacáridos y polioles que están parcialmente acilados | Authors: | Arcos Jiménez, José Antonio; Otero Hernández, Cristina | Issue Date: | 10-Oct-1997 | Citation: | EP 0 945 516 A1 | Abstract: | [EN]The process refers to highly selective enzymatic production of monosaccharides and mono- polyols and/or disubstitued with fatty acids. The procedure is based on the simple mixture of polyol or monosaccharide with the fatty acid, the addition of solvent, and the use of lipases that permit the highly selective obtainment of these products without catalysts or toxic agents. The water produced during the process must be continuously removed throughout the same. The invention belongs to the alimentary, pharmaceutical, cosmetic and chemical sectors. The products obtained are excellent biodegradable and biocompatible non-ionic tensioactive agents which are used as additives for their emulsifying, oily, thickening and moisturising properties. [ES]El procedimiento refiere a la producción enzimática altamente selectiva de monosacáridos y de mono polialcoholes y/o disubstitued con los ácidos grasos. El procedimiento es basado en la mezcla simple de polialcohol o de monosacárido con el ácido graso, la adición de Disolvente, y el uso de las lipasas que permiten la obtención altamente selectiva de estos productos sin los catalizadores o los agentes tóxicos. El agua producida durante el procedimiento se debe separar continuamente a través del mismo. La invención pertenece a los sectores alimentarios, farmacéuticos, cosméticos y químicos. Los productos obtuvieron a agentes tensioactive no iónicos biodegradables del son y biocompatibles excelentes que son utilizado como aditivos para su emulsionar, oleoso, el engrosamiento y las propiedades moisturising. | Description: | Fecha de solicitud: 04.10.1996.- Titular: Consejo Superior de Investigaciones Científicas (CSIC). | URI: | http://hdl.handle.net/10261/31338 |
