Description

Fluorescent brightener ER-II is a fluorescent compound that has been used in the textile industry. It is synthesized by refluxing 2-cyanostyrene and 4-cyanostyrene with zinc chloride in benzyl alcohol as a solvent. The synthesis method is a type of organic synthesis that involves the chemical reaction of two or more substances, usually organic reactants. Fluorescent brightener ER-II has been used to treat industrial wastewater from textile factories. This compound can be hydrolyzed to produce an acid or oxidized to produce a salt. In addition, it can be crystallized for further use.
