Abstract
AbstractTo prevent the ozone layer depletion, we proposed a new dechlorination process at room temperature and atmospheric pressure. We have a strong interest in reforming reaction of chlorodifluoromethane (CHClF2, HCFC22) to difluoromethylether (CH3OCHF2), because fluoroethers are expected to be the third generation refrigerants. In a previous paper, we reported that the model that NaCl precipitation, which disturbed mixing of a solution, decreased the reaction rate as the reaction proceeded. In this work, we found that the concentration of HCFC22 was kept constant and smaller than the solubility. The Reaction rate constant k1 was estimated from NaCl production rate and volumetric coefficient KLa was estimated from material balance of HCFC22 in a solution at stationary state. Calculation results gave excellent agreement with experimental data.
