  • Patent number: 4917930
    Abstract: Compositions having enhanced gas and drug transporting capability, are prepared by providing a perfluoro compound dispersed in an aqueous medium with a surfactant to form an aqueous initial dispersion, concentrating the perfluoro compound phase of the dispersion as by centrifugation or filtration, wherein a portion of the surfactant remains complexed with the particles of the perfluoro compound phase and the balance of the surfactant is in the aqueous phase, separating the phases, and redispersing the particles of the concentrated perfluoro compound phase to form a final dispersion in which greater than 65% by weight, and preferably at least 75%, of the surfactant present is complexed with the perfluoro compound particles.

  • Patent number: 4895680
    Abstract: Hydrocarbon, and particularly lower molecular weight alkanes and cycloalkanes, may readily be oxidized with air or O.sub.2 to form such products as alcohols, ketones, and the like in high yields when there is employed as the catalyst a highly active nitride-activated metal coordination complex having the structure ##STR1## where M is a transition metal; " " is a ligand; and X is a nitride. Certain dimeric forms of the above catalyst are also employed herein. It has also been discovered that Group IV through VIII transition metal nitrides are also highly effective oxidation catalysts for lower molecular weight hydrocarbons such as alkanes.

  • Patent number: 4895987
    Abstract: Ruthenium-cobalt- or cobalt-containing catalysts which have been promoted with phosphonites or phosphinites effectively catalyze the dealkoxyhydroxymethylation of aldehyde acetals to form glycol monoethers. Methylal, for example, may be reacted with syngas, i.e., CO and H.sub.2, in the presence of these phosphonite- or phosphinite-promoted cobalt or ruthenium- cobalt catalysts to form the monomethyl ether of ethylene glycol. In a like manner acetaldehyde may be converted to the corresponding propylene glycol monoether. The process may advantageously be carried out with high yields and selectivities in the presence of a polar or non-polar organic solvent in combination with the catalyst system of this invention.The invention is also directed to the phosphonite- or phosphonite-promoted cobalt and ruthenium-cobalt catalyst system per se.
