STEADY STATE SIMULATION OF ETHYL ACETATE

Ethyl acetate is used in manufacturing of nail polish remover [2] Explosive [3] Ethyl acetate is produced through esterification of ethyl alcohol and acetic acid This process is described as an acid catalyzed equilibrium synthesis developed by Emil Fischer [4] The condition chosen provide the maximum purity upto 99% of ethyl acetate

EXPERIMENT 5 SYNTHESIS OF ESTERS USING ACETIC

Like Fischer esterification this reaction is catalyzed by acid but unlike Fischer esterification it is very fast and irreversible In this experiment you will choose one of the following four esters -- propyl acetate isopentyl acetate benzyl acetate n-octyl acetate -- and synthesize it

Upgrading oxygenated Fischer

The production of ethyl acetate from bioethanol and then transesterification of fats and oils with the use of ethyl acetate allows managing all the renewable raw materials Thus the process enables the biosynthesis of biodiesel without glycerine by-product and potentially would result in the increase in the demand for ethyl acetate
