effectively maximize the rate of the reaction. Mr. Dianin then realized that the only thing that would noticeably accelerate the procedure of producing the desired chemical is a strong acid‚ like sulfuric acid (H2SO4)‚ chloric acid (HClO3)‚ hydrobromic acid (HBr)‚ and the most famous of all‚ hydrochloric acid (HCl). The required physical state of the reaction between the two phenol groups and the acetone group in order to produce BPA is condensation‚ the opposite of evaporation. Therefore‚ the chemical structure
