PROCESS FOR PREPARING CHLORINE BY OXIDATION PF HYDROGEN CHLORIDE

摘要

The catalyst for manufacturing chlorine is made by; (a) mixing the aqueous solution of CrO3 of 6 anions with ethanol; (b) heating and refluxing at above 90 deg.C; (c) calcinating at 400-500 deg.C for 3-10 hrs after seperating and drying the precipitate;(d) molding with 3-10 wt% stearic acid dissolved in chloroform added. Chlorine is prepared by reacting HCl and oxygen at the molar ratio of 4:1-4:4 at 350-375 deg.C under the catalyst Cr2O3.
