Activation enthalpy increases in the growth stage, causing the activation energy barrier to decrease. The influence of process parameters on the rate of the α-HH-DH hydration reaction follows the order SO4 2- ion concentration phosphoric acid concentration temperature. Therefore, controlling the three parameters of temperature, phosphoric acid concentration, and SO4 2- ion concentration are important for improving the conversion rate of α-HH-DH and the purity of DH products in the production of wet process phosphoric
