A synthesis has to be proposed for cyclomethycaine from 4-hydroxybenzoic acid and 2-methylpiperidine. Concept introduction: Esterification reaction: In an esterification reaction, carboxylic acid combines with an alcohol in presence of little concentrated sulphuric acid to produce an ester. Esters reacts with ammonia to form amides. Acid chlorides are most often prepared by treating a carboxylic acid with thionyl chloride. L i A l H 4 is a powerful reducing agent which reduces carboxylic acids to primary alcohol.

Question

Part 1. Draw monomer units of the following products and draw their reaction mechanism 1) Bakelite like polymer Using: Resorcinol + NaOH + Formalin 2) Polyester fiber Using a) pthalic anhydride + anhydrous sodium acetate + ethylene glycol B)pthalic anhydride + anhydrous sodium acetate + glycerol 3) Temporary cross-linked polymer Using: 4% polyvinyl alcohol+ methyl red + 4% sodium borate

Answer 1

Question

Definition Definition Class of organic compounds that contain a carboxyl group ( - COOH ) and has a general formula R - COOH or R - CO 2 H , where R refers to the alkyl, alkenyl, aryl, or other groups. They can undergo different chemical reactions, such as acid-base reactions, esterification, and oxidation. These are essential components of living organisms, playing important roles in metabolic processes, signaling, and as pharmaceuticals.
