Bronopol Production from nitromethane, formaldehyde, calcium chloride, and sodium hydroxide

This report provides an extensive cost evaluation of Bronopol production from nitromethane, formaldehyde, calcium chloride, and sodium hydroxide. The manufacturing process of Bronopol involves the addition of nitromethane, formaldehyde, calcium chloride and sodium hydroxide into the reaction equipment, followed by stirring. To this solution, bromine and dichloroethane are added below 0?. The dichloroethane is vaporized after the dichloroethane layer is separated, then the white solid (coarse product) will be obtained. The water layer of the reactants is extracted with ether, followed by vaporizing the ether in the ether extract, and to obtain another part of the coarse product. Finally, combine the coarse products and recrystallize them with ether to obtain the pure Bronopol.
