  • Patent number: 5824769
    Abstract: A process is described for removing heteropoly compounds from heteropoly compound-contaminated polyethers, polyesters and/or polyether esters, which comprises admixing the polymer or a solution of the same with a compound which contains at least one heteroatom which is selected from the group consisting of central atoms of heteropolyacids, is non-protic and is of a polarity so low that its addition leads to the heteropoly compounds separating out in a separate phase, and separating off the precipitated heteropoly compound phase. The remaining polymer phase is preferably further purified using a solid adsorbent.

  • Patent number: 5824834
    Abstract: The invention relates to a process for the production of acetylene and synthesis gas by partial oxidation of hydrocarbons with oxygen, wherein the gaseous reactants are separately preheated, intimately mixed in a mixing zone, reacted after passing a burner block and rapidly quenched with an aqueous quench medium after reaction, further characterized in that the aqueous quench medium is recirculated in a closed system. Preferably the ratio of the gaseous reactants is selected in such a way that acetylene and soot produced in the reaction are obtained in a weight ratio of 50 to 500.

  • Patent number: 5821390
    Abstract: A gas-phase mixture of propene and oxygen is catalytically oxidized by passing a reactant gas mixture comprising propene and oxygen through a plurality of catalyst containing contact tubes in a fixed bed reactor and simultaneously passing only one heat-exchange medium at elevated temperature over the exterior surfaces of the contact tubes in a longitudinal flow pattern which is cocurrent with the direction of flow of the reactants through said tube; simultaneously superposing a transverse flow on said longitudinal flow of heat exchange medium by means of an arrangement of successive baffles along the contact tubes which leave passage cross-sections free, thereby resulting in a meandrous flow of the heat-exchange medium through the reactor and setting the flow rate of said heat-exchange medium so that its temperature between the point of entry of the medium into the reactor and its point of exit increases by 2.degree. to 10.degree.
