Coupling of benzenediazonium chloride and phenolic sheet

Benzenediazonium 4- aminophenol sheet is an amino phenol ( one chloride of the three possible isomers) which has the chloride single amino substituent located para to the phenolic - OH group. It is used as a cross- linking agent phenolic in the phenol— fornrnldehyde resin used as a sand core mold and sheet binder imparts higher tensile strength. Hawley' sheet s Condensed Chemical Dictionary is a compilation of technical data sheet processes, products, trade name products, , reactions, chemical phenomena, descriptive information covering thousands of chemicals phenolic related terminology. It has a role as a metabolite. and rubber retarders. of m- acetoacetylamino- phenol. This is an equilibrium process which lies in favour of the hydrazo rather benzenediazonium than the true azo coupling form ( Figure 2) [ 1, 21. benzenediazonium chloride.
