Claim 1
Independent Claim
120 words
IN THE PRODUCTION OF HIGH-MOLECULAR-WEIGHT ALCOHOLS, THE PROCESS WHICH COMPRISES REACTING ETHYLENE AND ELEMENTAL OXYGEN IN A REACTOR AT TEMPERATURES ABOVE ABOUT 180*C., INTRODUCING ETHYLENE INTO THE REACTOR AT A RATE TO MAINTAIN THEREIN ETHYLENE PARTIAL PRESSURES BETWEEN ABOUT 500 TO 5000 P. S. I., CONTINUOUSLY INTRODUCING ELEMENTAL OXYGEN AT A RATE OF BETWEEN ABOUT ONE AND TWENTYFIVE STANDARD CUBIC FEET PER HOUR PER CUBIC FOOT OF REACTOR, CONTINUING THE OXIDATION AND POLYMERIZATION UNTIL OXYGENATED POLYMERIC MATERIALS OF ETHYLENE WITH AN AVERAGE MOLECULAR WEIGHT ABOVE 200 AND CONTAINING BETWEEN ABOUT 5 TO 25 PERCENT OXYGEN ARE OBTAINED, AND REDUCING SUBSTANTIALLY ALL OF THE REDUCIBLE FUNCTIONAL GROUPS OF THE POLYMERIC MATERIAL RESULTING FROM THE REACTION TO HYDROXY GROUPS TO PRODUCE ALCOHOLS.
