Question

Explain " esterification process ".​

Answer 1

Explanation:

Esterification is a chemical reaction that forms at least one ester (= a type of compound produced by reaction between acids and alcohols). Esters are produced when acids are heated with alcohols in a process called esterification. An ester can be made by an esterification reaction of a carboxylic acid and an alcohol.

Answer 2

ANSWER:

=> Esterification is the process of making ester by combining an alcohol with a carboxylic acid.

Reaction:

$\bf{C_{2}H_{5}OH + CH_{3}COOH \longrightarrow CH_{3}COOC_{2}H_{5}+H_{2}O}$

Here ethanol reacts with ethanoic acid from ethyl ethanoate (an ester) along with water.

Esters cannot be directly reacted with a base. They should first be converted back to carboxylic acid and alcohol and the carboxylic acid will react with the base to form soap.

$\bf{C_{2}H_{5}COOCH_{3} + H_{2}O \longrightarrow CH_{3}COOH + C_{2}H_{5}OH}$

$\bf{CH_{3}COOH + NaOH \longrightarrow CH_{3}COONa + H_{2}O}$

Extra Info:

Saponification:

Saponification is the process in which an ester reacts with a strong base like KOH and NaOH to form salt of Na or K  having long chain of carboxylic acid and the constituent alcohol.

Example:

$\bf{CH_{3}OOC_{2}H_{5}+NaOH \longrightarrow CH_{3}COONa + C_{2}H_{5}OH}$

Here ester reacts with sodium hydroxide to form sodium ethanoate along with ethanol (alcohol).
