Synthesis of Apple Ester B |
| |
| Abstract: | Apple ester B was synthesized by reaction of ethyl acetyl acetate and 1,2 propanediol,and aluminium sulfate as catatlyst.The optimum conditions were found out as follows:the ratio of ethyl acetyl acetate to 1,2 propanediol to benzene to aluminium sulfate was 0.2 mol to 0.4 mol to 40ml to 3g for 1.5 hours.On these conditions the yield reached 90.2%. |
