摘要:

以甘油(0.5mol)、丁酸(0.4mol)为原料,四氯化碳(25ml)为带水剂,经磷酸(用量为甘油质量的4.0%)催化酯化合成丁酸甘油酯。用FT-IR 对产品结构进行定性分析,结果表明可合成目标产物,经测定单甘酯含量为60.2%。以合成的丁酸甘油酯作为乳化剂应用于油脂的微胶囊化中,取得了较好的效果。

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
