Abstract:

Glyceryl butyrate was synthesized via esterification from glycerol (0.5 mol) and butanoic acid (0.4 mol) with carbon tetrachloride (25 ml) as the water carrying agent and phosphoric acid as the catalyzer. The structural analysis by FT-IR spectroscopy showed that the target product was obtained, which contained 60.2% glyceryl monobutyrate. The use of this synthesized glyceryl butyrate as an emulsifier led to a high microencapsulation efficiency of soybean salad oil.

Key words: glyceryl butyrate, IR analysis, microencapsulation
