Abstract: THE PRODUCTION OF STYRENE BY DEHYDROGENATION OF ETHYLBENZENE WITH OXYGEN OR A GAS CONTAINING MOLECULAR OXYGEN IN THE PRESENCE OF IODINE, ISOLATION OF THE CRUDE STYRENE AND DISTILLATION OF THE CRUDE STYRENE WITH THE RECOVERY OF PURE STYRENE, WHEREIN THE CRUDE STYRENE IS IN PART CATALYTICALLY HYDROGENATED. STYRENE IS AN IMPORTANT MONOMER.

Abstract: THE RECOVERY OF BROMINE AND/OR IODINE FROM THE REACTION PRODUCTS OF OXYDEHYDROGENATIONS OF HYDROCARBONS IN WHICH BROMINE AND/OR IODINE SERVES AS A CATALYST, WHEREIN THE REACTION PRODUCT LEAVING THE REACTOR IS TREATED WITH AN AGUEOUS AMMONIA SOLUTION TO WHICH HAS BEE ADDED AN AMOUNT OF HYDRAZINE SUFFICIENT FOR THE REDUCTION OF THE ELEMENTARY CONSTITUENTS. THE AQUEOUS PHASE IS SEPARATED AND THE BYPRODUCTS CONTAINING BROMINE AND/ OR IODINE SEPARATED IN THE WORKING UP OF THE ORGANIC PHASE ARE BURNT AND OXYGEN-CONTAINING GASES AND THE GAS FROM THE COMBUSTION IS SCRUBBED WITH AN AMMONIA SOLUTION CONTAINING HYDRAZINE.
