How is the Bisphenol A BPA Sulfuric Acid Method operated?
Bisphenol A bpa Sulfuric Acid Method
Phenol and acetone undergo a condensation reaction in sulfuric acid with a mass concentration of 72.5%–73.0% at 35–45°C. The product is then washed with water, crystallized, separated by centrifugation, and dried to obtain bisphenol A suitable for general-purpose epoxy resins and flame retardants. The consumption rates per ton of product are approximately 0.925 tons of phenol, 0.285 tons of acetone, and 0.500 tons of sulfuric acid (98% purity).
This Bisphenol A bpa method features relatively simple equipment and processes. However, it suffers from high raw material consumption, leading to elevated product costs. It also causes corrosion to equipment, pipelines, valves, and the production site, while generating significant amounts of waste. Moreover, the product quality does not meet the requirements for producing polycarbonate or food-grade epoxy resins.
