Lederer Manasse Reaction || Phenol Formaldehyde Reaction || BSc #NEET #JEE #CUET #organic chemistry

When phenol is treated with 40% aqueous solution of formaldehyde (formalin) in the presence of a dilute acid or alkali at low temperature, a mixture of o-and p-hydroxy benzyl alcohol is formed. These reactions are the basis of the preparation of phenol formaldehyde resins. These materials were developed by Backland and are hence called bakelite. They are thermoplastic solids soluble in many organic solvents. When warmed with hexa methylene tetramine. (CH2)6N4 , which splits up to formaldehyde and ammonia, further methylene bridges are formed and a three-dimensional polymer results.
