  • Patent number: 5091350
    Abstract: A process for separating rhodium from mixtures thereof, comprising extracting said rhodium with an aqueous solution of a rhodium complexing agent and a solubilizer. A process for preparing aldehydes in the presence of both the complexing agent and the solubilizer is also set forth. The solubilizer is generally selected from salts of carboxylic acids having 8-20 carbon atoms, alkyl sulfonates, alkyl aryl sulfonates, amines and quaternary ammonium compounds of Formula II ##STR1## wherein A is alkyl, alkoxy, hydroxyalkyl, aryl having 6-25 carbon atoms, or R.sup.7 CONHCH.sub.2 CH.sub.2 CH.sub.2 --wherein R.sup.7 is alkyl having 5-11 carbon atoms; B is an alkyl having 1-25 carbon atoms, an aryl having 6-25 carbon atoms, or an .omega.-hydroxy alkyl having 1-4 carbon atoms; C and D are each independently an alkyl or .omega.

  • Patent number: 4710321
    Abstract: The invention relates to new quaternary ammonium salts of di and trisulfonated triarylphosphines as well as a process for their preparation. The salts are of Formula I ##STR1## wherein Ar.sub.1, Ar.sub.2, and Ar.sub.3 are each independently an aryl; X.sup.1, X.sup.2, and X.sup.3 are each independently a sulfogroup; y.sup.1, y.sup.2, and y.sup.3 are each independently 0 or 1, provided that their sum is at least 1; A is an alkyl, hydroxyalkyl, aralkyl, or aryl having 6-25 carbon atoms; B, C, and D are straight chain or branched alkyl having 1-4 carbons; and n is a whole number of 1-3.

  • Patent number: 4693168
    Abstract: A method and apparatus for aiming indirectly aimable weapons free from tipping and tilting angle and independent of the oblique position of the weapon. The position of the weapon is supplied with respect to an earth coordinate system by a position reference system. These values, along with theoretical angular values derived through ballistics computations, are separately converted to a coordinate system that is fixed with respect to a weapon platform. The weapon is aimed in accordance with differences formed between the theoretical and actual positions of the weapon. A cross-hair that indicates actual position is displaced laterally on a screen when the weapon is pivoted and vertically when the weapon is raised or lowered. The lateral and elevation movements of the weapon are decoupled allowing the correct position to be directly and independently set with respect to both axes.

  • Patent number: 4616096
    Abstract: A method for the production of aldehydes from olefins with CO/H.sub.2 in the presence of a water-soluble rhodium-containing catalyst system is described. The reaction proceeds at 0.1 to 10 MPa and 20 to 160.degree. C. Ultrasound acts on the reaction mixture, consisting of an aqueous catalyst, an olefin, synthesis gas and the end products.

  • Patent number: 4472526
    Abstract: The present invention relates to a process for producing ethanol and n-propanol by reacting methanol with carbon monoxide and hydrogen at elevated pressure and temperature. A system consisting of a cobalt compound, a ruthenium compound, an iodide, and an organic phosphine serves as the catalyst. The organic phosphine contains a group having a --SO.sub.3 M, --COOM or --OSO.sub.3 M radical.
