糠酸正丁酯香料催化合成的新方法

Catalytic Synthesis of Furoic Acid-N-Butyrate Flavor

以糠酸和正丁醇为原料,改性钼镍粉作催化剂取代以往常用的硫酸作催化剂,合成糠酸正丁酯香料.实验结果是:在优化条件下,合成的糠酸正丁酯产率达到85.9%,比其他合成的糠酸正丁酯产率提高了十几个百分点.结论为改性钼镍粉作催化剂催化合成糠酸酯类香料,催化剂原料广且价廉,制作催化剂方便,制备好的催化剂能反复使用,催化活性高,不腐蚀设备,不污染环境,工艺简单,酯化产率高,在工业上制取糠酸酯类有推广和应用价值.

A new method employing furoic acid and the n-butanol to synthesize the furoic acid-n-butyrate flavor has been reported in this paper. With modified Mo-Ni powder as catalysts, the yield can reach up to 85.9% at these optimized conditions.
