Production Process


Add 286 kg of zinc powder and 500 kg of water into the beating tank, and after pulping, add it to the shell-and-tube reactor, and absorb about 550 kg of SO2 to obtain zinc hydrosulfite (the reaction temperature is maintained at 40-45 °C, and the end point is pH value is 3 to 3.5).
In addition, the formaldehyde of 698 kg 40% is added in the reactor, the above-mentioned zinc hydrosulfite aqueous solution is added dropwise under stirring, and gradually heat up, when the temperature rises to 95~100 ℃, add a total of 257 kg of zinc powder in batches, react under the insulation For several hours, the end point is less than 1% unreacted substance. The precipitate was left to stand, and the precipitate was transferred to a displacement kettle. After washing with clean water, 755 kg of 42% sodium hydroxide solution was added under stirring. The reaction was carried out at 65°C until the free base content reached 0.3% to 0.5%. The reactants were filtered to remove impurities, and the filtrate was clarified for 48 h and concentrated in vacuo. Cool to crystallize and pulverize to get the finished product.
