    Abstract: Process for the specific synthesis of monoesters between a fatty acid and O-isopropyliden-1,2alpha-D-glucofurannose comprising the acylation of di-O-isopropydilen-1,2:5,6alpha-D-glucofurannose and the elimination on an ion exchange resin of ions (H+) from the protection isopropyliden-5,6 to obtain O-acyl-3 O-isopropyliden-1,2alpha-D-glucofurannose. The latter may be quantitatively transformed into pure O-acyl-6 O-isopropyliden-1,2alpha-D-glucofurannose. These monoesters wherein acyl means (i), with R=alkyl having a number of carbons equal to or higher than 7, are fermentation adjuvants, swelling agents, gelifying agents, emulsifiers, microemulsifiers usable in the food industry, pharmacy, sanitary industry and cosmetics.
