- Molecular formula:C6H12O2
- Molecular Weight:116.16
Yield:105-54-4 99%
Reaction Conditions:
with HZSM-5 at 170; for 12 h;Temperature;
Steps:
8-11; 2 Preparation of ethyl butyrate by reaction of butyric acid and ethanol
General procedure: Filling the above catalyst into a fixed bed reactor,The two ends are packed with quartz sand, the butyric acid and ethanol are mixed at a molar ratio of 0.99:1, and then vaporized at a certain rate into a vaporizer to form a raw material gas stream and enter the fixed bed reactor.The vaporizer temperature is 170 ° C, and the residence time of the feed gas stream in the fixed bed is 10 h.Fixed bed reaction temperature 170 ° C,Continuous production of ethyl butyrate from the other end of the fixed bed,Water and a small amount of unreacted ethanol,The oil phase is simply rectified after separation by oil-water separatorObtaining ethyl butyrate with a purity of 99.5%,The yield of ethyl butyrate is 98%.Ethyl butyrate is 99% selective.
