Abstract
The present invention discloses synthesis process of vanillyl ethyl ether. Vanillyl ethyl ether is prepared with vanillyl alcohol and ethanol and through reaction at reflux temperature for 3-4 hr in the presence of catalyst of concentrated sulfuric acid, hydrochloric acid or cationic exchange resin Amberhite IR-120(H). Adopting cationic exchange resin Amberhite IR-120(H) as catalyst can result in high yield, low cost and less wastes.
Description
Affiliated technical field
The present invention relates to a kind of synthetic method of spices vanillyl ethyl ether
Background technology
Vanillyl ethyl ether is natural to be present in the fragrant pod beans, is mainly used in bakery product, snack food product, and chewing gum is in the food such as freezing milk preparation.Vanillyl ethyl ether is regarded as GRAS by FEMA, and FEMA is numbered 3815, and calendar year 2001 is estimated through JECFA again and thinks and can use safely.Present synthetic method reaction yield is low, cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of reaction yield height, the synthetic method of the spices vanillyl ethyl ether that cost is low.
Vanillyl ethyl ether synthetic: under reflux temperature, vanillic alcohol and ethanol synthesis and make.It is a kind of new synthetic method that the present invention prepares vanillyl ethyl ether, has adopted a kind of new catalyzer in reaction.Its reaction formula is as follows:
Beneficial effect of the present invention is: adopt new catalyzer, improved reaction yield, reduced reaction cost, the three wastes are few.
Embodiment
Further specify enforcement of the present invention below:
In 500 milliliters of three-necked bottles of agitator, thermometer and reflux condensing tube are housed, add 80.0 gram (0.52mol) vanillic alcohols, 239.0 gram (5.2mol) ethanol, 50 gram Zeo-karb Amberhite IR-120 (H).Stir back flow reaction 3-4 hour.Reaction is finished, and filters, and reclaims Zeo-karb Amberhite IR-120 (H).Normal temperature reclaims ethanol down, and underpressure distillation gets product 66.3 grams, and yield is 70.1%.
Claims (1)
1. the synthetic method of vanillyl ethyl ether, it is characterized in that: under reflux temperature, vanillic alcohol and ethanol synthesis make vanillyl ethyl ether, and temperature of reaction is a reflux temperature, reaction times is 3-4 hour, and the catalyzer that reacts used is the vitriol oil, hydrochloric acid, Zeo-karb.
