WebBase Hydrolysis of Chlorobenzene. Reaction type : Nucleophilic Aromatic Substitution. Summary. This is a useful industrial method for the synthesis of phenol. Reagents : Usually NaOH, 350 o C followed by an acidic work-up to neutralise the phenoxide. The reaction occurs via the elimination-addition mechanism via a benzyne intermediate. WebAn early method of preparing phenol (the Dow process) involved the reaction of chlorobenzene with a concentrated sodium hydroxide solution at temperatures above 350 … WebAromatic Substitution Reactions Part II. 4. Electrophilic Substitution of Disubstituted Benzene Rings. When a benzene ring has two substituent groups, each exerts an influence on subsequent substitution reactions. The activation or deactivation of the ring can be predicted more or less by the sum of the individual effects of these substituents. century aluminum hawesville ky jobs
