三种（乙基）麦芽酚酯化合物的合成研究

Study on Synthesis of Three （Ethyl）Maltol Carboxylate Compounds

以麦芽酚和丙酰氯为原料，合成了丙酸麦芽酚酯，并考查了反应温度和反应时间对丙酸麦芽酚酯收率的影响，确定了反应优化条件为反应温度60-70℃，反应时间3h。以麦芽酚、乙基麦芽酚和丁酰氯为原料，分别合成了丁酸麦芽酚酯和丁酸乙基麦芽酚酯。以FTIR、GC—MS确定了产品的结构。

Maltol propionate was synthesized by the reaction of maltol and propionyl chloride. The effect of reaction temperature and reaction time to the yield of maltol propionate was investigated. The optimum reaction conditions were selected as reaction temperature 65-70℃ and reaction time 3h. Maltol butyrate and ethylmaltol butyrate were synthesized by the reaction of maltol and ethylmaltol with butyl chloride respectively. The structures of obtained products were identified by FTIR and GC-MS.
