How is the formation of ethyl acetate from ethanol and acetic acid

Formation of ethyl acetate from ethanol and acetic acid is one of the most important steps in the process of fermentation. Ethanol and acetic acid are the two main ingredients used to produce ethyl acetate. The objective is to use chemical reaction to convert ethanol and acetic acid into ethyl acetate.

The conversion becomes complete when it reaches equilibrium concentration with contact time duration. In this reaction, the condensation reaction between acetic acid and ethanol is the most important. It starts with a slight overpressure which causes a reaction in the water phase. The product from this phase formation is called an acetate ion (O-C₂H₃O₂-).

Acetate ions (O-C₂H₃O₂-) are attracted in the product phase by hydrogen. In that process, hydrogen combines with acetate ions and forms ethyl alcohol (CH₃OH) and methyl acetylene (CH₂=CCl). These are two components that eventually form ethyl acetate when the process of equilibrium concentration concludes.

The equilibrium process is a two step process in which both the products reach their respective concentrations. Ethyl alcohol and methyl acetylene form the equilibrium mixture in 1850 degree C at a certain time after the start of reaction.

The reason why this reaction is called a condensation reaction is because both acetaldehyde (O-C₂H₅CHO) and methyl acetylene (CH₂=CCl) form as products of this reaction. The formation of these compounds is caused by the combination of acetate ions (O-C₂H₃O₂-) with hydrogen. The formation of these compounds is what makes this reaction as an efficient one. This explains the formation of ethyl acetate from ethanol and acetic acid.

Properties of ethyl acetate

1. Ethyl acetate is a colorless gas.

This gas is widely used as a solvent. It is used in the production of ethylene glycol, acetone and different types of drugs. It is also used in the production of detergents, solvents and as a gas.

2. Ethyl acetate is soluble in water but very insoluble in alcohol.

This makes it possible to be very effective in the production of ethyl acetate by using aqueous solutions. The reaction is possible to occur because of its solubility in water.

The reaction is highly exothermic in nature and therefore it is hard to predict the final state of equilibrium, especially when the vapor pressure of all the reactants vary significantly. In order to calculate the equilibrium condition, we have to use Raoult's law which states that "the vapor pressure of a solution is equal to the sum of vapor pressures at each component."

This law will be helpful in determining which component will be present in large quantities when finally reaches equilibrium.

3. Ethyl acetate is a readily available compound.

Ethanol and acetic acid are relatively easy to get. This makes this process possible to be used for a large number of applications. Other than being a solvent, it is possible to use it in the production of detergents and other products with an aroma of ethyl acetate.

4. Ethyl acetate is very soluble in water and has a high boiling point.

Median boiling point of ethyl acetate is 59℃ while its maximum value is 1881℃ at absolute pressure 14 KPa (1atm). This compound is also soluble in ethanol and acetic acid. It is also present in evaporated water and its vapor pressure is about the same as that of alcohol.

5. Ethyl acetate is environmentally friendly.

Due to its high boiling point, ethyl acetate has low environmental impact when compared to other gases used as fuel for engines and fluorinated compounds. It only releases CO₂ to the atmosphere when it decomposes by itself or when it reacts with oxygen in the air, which are both harmless causes. The low environmental impact also makes this product safe for use around living organisms because it doesn't have any health hazards like other carbon-based products like carbon dioxide, hydrocarbons and fluorocarbons have.

6. Ethyl acetate is a component of fuels.

Ethanol and acetic acid are components of fuels used by vehicles in everyday life when they are manufactured in plants. Direct conversion of these products into ethyl acetate presents an economical advantage because it is possible to produce large amounts at the same time with efficiency that is lower than the production of other products used as fuels like gasoline, kerosene and diesel. This process is also a good substitute for fossil-based products as it can be produced from renewable resources such as steam and solar energy. It has great advantages because it produces a high quality product without releasing harmful substances to the environment which makes this product sustainable and environmentally sound.

In conclusion, formation of ethyl acetate from ethanol and acetic acid is a very effective process because it is highly exothermic in nature which creates a high energy value and the reaction is very fast. It has been proven to be an efficient process for producing ethyl acetate from renewable resources.
