Glyptal

Vedclass · Answer

(C) The starting material is $o$-methylacetophenone (or $2-$methylacetophenone). Treatment with $KMnO_4/KOH$ followed by acidification with $dil. H_2SO_4$ leads to the oxidation of both the acetyl group $(-COCH_3)$ and the methyl group $(-CH_3)$ attached to the benzene ring into carboxylic acid groups $(-COOH)$. The product $(Q)$ is phthalic acid (benzene$-1,2-$dicarboxylic acid). Phthalic acid is a key monomer used in the synthesis of the polymer Glyptal (polyethylene phthalate) by reacting it with ethylene glycol.
