The effects of catalyst type,dosage of AlCl3-ZnCl2,continuous re-use of distillate and pilot scale-up operation on the synthesis of chloroethane are studied.Three kinds of hydrogen chloride gas supplying methods are explored for synthesis of chloroethane.Both automatic control technology and large-scale reactor are employed in the production of chloroethane.Study results show that AlCl3-ZnCl2 is an excellent catalyst system for the synthesis of chloroethane.The catalyst system exhibits the best catalytic efficiency when the mole ratio of C2H5OH:HCl:AlCl3:ZnCl2 is 1:1.07:0.4:0.4.Higher yield of chloroethane will be gained when the distillate is continuously re-used.H2SO4-HCl method,decompose-enriched hydrochloric acid cycle system method and by-product hydrogen chloride gas method all are suitable hydrogen chloride gas supply methods.Among which,by-product hydrogen chloride gas method has more promising prospect.The application of automation control technology and large-scale reactor endows safety and efficiency for production. © 2020, China National Chemical Information Center.
