Questions You Should Know about Ethyl Acetate Plant and Process Technology

Ethyl acetate is a kind of organic compound with chemical formula C4H8O2. It is a kind of ester with functional group-COOR (there is a double bond between carbon and oxygen). It can undergo common reactions of general esters such as alcoholysis, aminolysis, transesterification and reduction. It is mainly used as solvent, edible flavor and cleaning deoiling agent.

Required Reagent

Glacial acetic acid 12mL (12.6g, 0.2mol); absolute ethanol 19mL; concentrated sulfuric acid 5mL; saturated sodium carbonate solution; saturated calcium chloride solution; anhydrous magnesium sulfate.

Operation Steps

Add 12mL glacial acetic acid and 19mL anhydrous ethanol to 100mL round bottom flask, slowly add 5mL concentrated sulfuric acid under shaking, mix evenly, add a few zeolites, install reflux condensation tube, heat reflux 30min. After it is slightly cold, it is changed to a distillation device, a few zeolites are re-added, and the crude ethyl acetate is obtained by heating and distilling in the water bath until there is no more effluent in the boiling water bath. Slowly add saturated sodium carbonate solution to the crude product under shaking until the organic phase is neutral. Transfer the liquid into the liquid separation funnel, shake and remove the water layer. The organic phase is washed first with 10mL water, then with 10mL saturated calcium chloride solution, and finally with water. Discard the lower liquid, transfer the ester layer to a dry conical bottle and dry it with anhydrous magnesium sulfate.

The dried crude ethyl acetate was filtered into a 50mL distillation bottle and distilled in a water bath to collect 73&#;~78&#; fractions.

Ethyl acetate can form a binary or ternary azeotrope with water and ethanol. The boiling point and composition are shown in Table 1. Despite the process of removing ethanol and water, the ethyl acetate obtained by distillation still contains a small amount of ethanol and water.

Raw Material for Ethyl Acetate Production

According to the Ethyl Acetate manufacturing plant project report, the key raw materials used in the production of Ethyl Acetate include acetaldehyde; ethanol and acetic acid; ethanol.

Manufacturing Process of Ethyl Acetate

The extensive Ethyl Acetate production cost report consists of the following major industrial manufacturing processes:

• Production via Tishchenko reaction: The manufacturing process of Ethyl Acetate takes place through the Tishchenko reaction which involves the dimerization of acetaldehyde to produce Ethyl Acetate and ethanol. In this reaction, two molecules of acetaldehyde react in the presence of a catalyst to form Ethyl Acetate as the final product.
• Production via Fischer esterification reaction: The manufacturing process involves Fischer esterification reaction. In this process, ethanol is reacted with acetic acid in the presence of an acid catalyst such as sulfuric acid to produce Ethyl Acetate and water.
• Production via dehydrogenation of ethanol: The production process involves the dehydrogenation of ethanol in the presence of catalysts such as copper and copper chromite to produce Ethyl Acetate as the final product and hydrogen as the by-product.

Ethyl Acetate is an organic compound and is an esterified product of ethanol and acetic acid. It is a colorless liquid that has a molecular formula of C4H8O2. It has a distinct fruity smell like the one in glues and nail paint remover. It is highly flammable and has a flashpoint of -4° C. It is very miscible with all the standard organic solvents (ketones, alcohols, esters, glycols). It has a molecular weight of 88. g/mol and a density of 0.902 g/cm3, which makes it less dense than water. Its vapors are heavier than air. Its boiling and melting points are 171°F / 77.1 °C and -83.6 °C / -118.5 °F, respectively. It has a flashpoint of 24°F / -4°C and a freezing point of -83.6 °C.
