  • Patent number: 6881759
    Abstract: The present invention is a novel process for methanol production in a liquid phase reactor from a synthesis gas comprising of hydrogen, carbon dioxide and carbon monoxide. The liquid phase reactor contains a solid catalyst suspended in methanol. In this innovation, methanol acts both as a product and as a suspension medium for the catalyst. The new innovation exploits the condensing conditions for methanol production. By operating at condensing conditions, the methanol partial pressure at equilibrium is higher than the boiling pressure of methanol at the given temperature. Hence the produced methanol of the equilibrium composition condenses creating the potential of more gas to be converted. Since equilibrium is not a limiting factor, high conversions can be obtained.

  • Patent number: 5002948
    Abstract: The present invention relates to novel piperazinylbutylindoles, -indazoles, the corresponding 2,3-dihydro derivatives and 2-indolones which have been found to have central serotonin activity with preference for the serotonin 5-HT.sub.lA receptor.Compared to the anxiolytic drug buspirone, and other clinically investigated compounds such as ipsapirone and gepirone, most of the present compounds have lower efficacy at the 5-HT.sub.lA receptor which implies less side effects related to activation of the receptors.The invention also includes acid addition salts, methods of preparation, pharmacetical compositions and method of treating CNS disorders occuring in anxiety, depression, aggression and in alcohol abuse, or in states of disease related to the cardiovascular, gastrointestinal and renal systems, by administering the aforementioned derivatives.Separation and use of the stereo isomers of the 2,3-dihydro derivatives and 2-indolones are also part of this invention.
