    Abstract: In the catalytic reaction of ammonia or formamide with CO and H.sub.2, exceptionally high yields of mono- and di-methyl formamide are obtained among the reaction products when the reaction is carried out in the presence of a platinum group catalyst soluble in the reaction medium, particularly a compound or complex of ruthenium or rhodium, employing a relatively non-volatile polar solvent which does not contain an active methyl function and which does not enter into the reaction producing formamide compounds. The pressure employed is in the range of 3000-8000 psi with a hydrogen partial pressure of at least 1500 psi, the preferred solvent being sulfolane.

    Abstract: Benzene or an alkylbenzene is reacted with hydrogen and an alkali metal such as potassium in the presence of a polyamine to produce cyclohexene or alkylcyclohexene and alkali metal hydride. The polyamine contains only C, N and H and has at least three nitrogens. Each nitrogen is linked to three carbons and each carbon bridge is at least two methylenes long. Representative polyamines are hexamethyl hexacyclen, hexamethyl triethylene tetraamine, tris(2-dimethylamino ethyl)amine and octamethyl pentaethylene hexamine. Cyclohexene is produced at high ratios with respect to cyclohexane.

    Abstract: A process is disclosed for making a highly fluorinated aromatic compound by contacting a perfluorocycloalkane, such as perfluorodecahydronaphthalene, with a complex of a metal from Groups IA and IIA of the Periodic Table and an organic electron acceptor. The reaction is carried out in an organic solvent and under reducing conditions which are relatively moderate. Best results are obtained using a perfluorocycloalkane having 2-4 condensed rings and a complex of either sodium or lithium and benzophenone thereby making a perfluorinated condensed ring aromatic compound such as perfluoronaphthalene or perfluorophenanthrene.

    Abstract: The present invention is a process for reversibly absorbing acid gases, such as CO.sub.2, H.sub.2 S, SO.sub.2, HCN and the like from gas mixtures. The gas mixture containing one or more of these acid gases is contacted with a hydrated salt of the compositionA.sub.x.sup.m+ B.sub.y.sup.n-.rH.sub.2 Owherein A.sup.m+ is a cation, B.sup.n- is the conjugate base of a weak acid having a pKa corresponding to an ionization constant of the acid greater than 3 as measured in dilute aqueous solution, m and n are independently integers from 1-4, x and y are integers such that the ratio of x to y provides a neutral salt and r is any number greater than zero up to the maximum number of moles of water which can be bound to the salt. The salt hydrate reversibly absorbs the acid gas from the gas mixture.

    Abstract: Benzene, or an alkylbenzene, is hydrogenated by reaction with hydrogen in the presence of a Group IVa or Va metal hydride catalyst. The catalyst may be a simple hydride such as ZrH.sub.2 or a hydride of an alloy such as Cu.sub.3 Zr or may be a complex material. One complex material is the reaction product of a Group IVa or Va metal halide, such as ZrCl.sub.4 with an alkyllithium or aryllithium, such as n-butyllithium, in a hydrocarbon solvent.
