Claim 1
Independent Claim
99 words
A PROCESS FOR THE SYNTHESIS OF ORGANIC OXYGEN-CONTAINING COMPOUNDS WHICH COMPRISES INTRODUCING INTO A PRESSURE RESISTANT VESSEL REACTANTS CONSISTING OF A HYDROXYALKANE, CARBON MONOXIDE AND HYDROGEN, REACTING THE SAID HYDROXYL-CONTAINING COMPOUND WITH CARBON MONOXIDE AND HYDROGEN UNDER A PRESSURE OF 1800 TO 5000 ATMOSPHERES IN THE PRESENCE OF A COBALTCONTAINING CATALYST, AT A REACTION TEMPERATURE WITHIN THE RANGE OF 100* TO 350* C., WHEREBY SIMULTANEOUS REACTION BETWEEN THE SAID HYDROXYLCONTAINING COMPOUND, CARBON MONOXIDE AND HYDROGEN TAKES PLACE WITH THE FORMATION OF A GLYCOL ETHER, AND THEREAFTER SEPARATION FROM THE RESULTING MIXTURE, THE GLYCOL ETHER PRODUCED BY THE SAID REACTION.
