Q22E - Organic Chemistry (Mcmurry)

Question

Draw the structure of Kedol, a polyester prepared by heating dimethyl 1,4- benzene dicarboxylate with 1,4- bis (hydroxymethyl) cyclohexane.

Step-by-Step Solution

Answer

The answer is,

Step 1: Esterification Reaction

The esterification reaction is the reaction taking place by the alcohols and carboxylic acids. The hydroxyl groups of alcohols and carboxylic group of acids undergo a reaction to leaving a water molecule giving an ester compound

Step 2:

The polyester kedol can be synthesized as shown below.

 Reaction

The reactants used are dimethyl 1,4- benzene dicarboxylate and 1,4- bis (hydroxymethyl) cyclohexane. They on heating undergo the removal of methanol to give the product Kedol. This is an esterification reaction.
