摘　　要：苹果酯一B广泛应用于花香型和果香型香精的调配,国内市场前景广泛。利用乙酰乙酸乙酯和丙二醇在对甲基苯磺酸催化下缩合,用甲苯作溶剂,制得苹果酯一B,产率为55%-57%,纯度为82.01%。Fructone- B with apple flavour now is applied widely in many aspects, as in food flavours and perfumes. The market need for ftuctorte- B becomes bigger andbigger. Fructone - B was synthesized by ethyl acetoacetie ester reaction with glycol in toluene solution, P- toluene sulfonic acid as catalyst. The yield was 55 %-57 %.The product purity was 82.01%.
