Abstract
Abstract A PROCESS FOR THE OXIDATION OF ETHYLENE AND PROPYLENE TO THE CORRESPONDING ALDEHYDE OR ACID IN WHICH A HETEROPOLYACID OR OXIDE IS FORMED FROM A FIRST COMPONENT, AN OXIDE OF VANADIUM, TUNGSTEN AND MOLYBDENUM, AND A SECOND COMPONENT, AN ACID OR OXIDE OF BORON, ALUMINUM, SILICON, TITANIUM, GERMANIUM, ZIRCONIUM, TIN, CERIUM, PHOSPHORUS, ARESENIC, ANTIMONY, BISMUTH, SULPHUR, CHROMIUM, SELENIUM, TELLURIUM, MANGANESE, IRON, COBALT AND NICKEL. THE ETHYLENE OR PROPYLENE IS BROUGHT INTO GAS-SOLID CONTACT WITH THE SOLID CATALYST ON A SUPPORT IN THE ABSENCE OF ANY LIQUID PHASE FOR THE CONTACT TIME OF 0.5 TO 10 SECONDS AT A TEMPERATURE OF 180* TO 400*C., A PRESSURE UP TO 10 ATMOSPHERES, A WATER VAPOR: OLEFIN MOLAR RATIO OF 1 TO 10 AND AN OXYGEN: OLEFIN RATIO OF 0.5 TO 5.
