Glucose dehydroabietate was synthesized from glucose and dehydroabietic acid in the presence of propanediol and base catalyst. The product exhibits good surface activity. Rosin is one kind of widely applied raw materials. The main components of rosin, resinolic acids, have hydrophobic phenanthrene structure. The acid group of resinolic acids can react with hydrophilic compounds to form a series of surfactants. Therefore, rosin can be used for surfactant production. Glucose is the most widely distributed and important monosaccharide. All plants can produce glucose via. photosynthesis. While glucose reacts with rosin, the product, glucose rosinate, exhibits excellent surface activity. Besides, just like sugar esters [1], the surfactant has the characteristic of non-toxic, easily degradable and harmless for environment. It can be applied widely in food and other industry. In the present paper, glucose dehydroabietate has been synthesized from dehydroabietic acid and glucose with propanediol as solvent. The optimum reaction conditions have been investigated. |
