  • Process for purifying hydrogen fluoride
    Patent number: 5108559
    Abstract: A process for manufacturing high purity anhydrous hydrogen fluoride (HF) having low levels of oxidizable impurities by electrolytically oxidizing the impurities. Specifically, trivalent arsenic impurity in the anhydrous hydrogen fluoride is oxidized to a non-volatile pentavalent arsenic compound. The resultant solution is distilled to recover high purity anhydrous hydrogen fluoride with low levels of arsenic impurity.
    Type: Grant
    Filed: October 1, 1990
    Date of Patent: April 28, 1992
    Assignee: E. I. Du Pont de Nemours and Company

  • Low pour crude oil compositions
    Patent number: 4926582
    Abstract: A low pour point crude oil composition is prepared by incorporating in a waxy crude oil an effective pour point depressant amount of an oil soluble ethylene-acryonitrile copolymer or terpolymer. The copolymer or terpolymer is usually added as a solution. In one aspect the invention relates to the pipeline transportation of the low pour crude oil composition.

  • Process for the preparation of linear olefins from triethylaluminum and tripropylaluminum via growth, isomerization and metathesis
    Patent number: 4435606
    Abstract: Internal olefins are subjected to metathesis closely coupled after an isomerization reaction to obtain desired molecular weight range linear olefins. Specific process steps and separation conditions are necessary to obtain the desired linear olefins.

  • Waterflood method
    Patent number: 4295980
    Abstract: An improvement is disclosed in the method of recovering hydrocarbons from a subterranean formation by use of an aqueous mixture containing an alkali metal hydrocarbon sulfonate and a solubilizing agent (e.g. isobutanol). Briefly, the improvement comprises using as the sulfonate an alkali metal C.sub.20 -C.sub.24 alkane sulfonate.

  • Preparation of aldehydes from alcohols
    Patent number: 4097535
    Abstract: An improved method of preparing an aldehyde by passing alcohol and air through a reactor containing a silver catalyst is disclosed. Briefly, the improvment comprises passing the alcohol and air through a zone, packed with silver catalyst, maintained at subreaction temperature prior to passing the reactants through the reaction zone. In a preferred embodiment, the reactants, after leaving the reaction zone, are passed through a zone containing inert material and maintained at a subreaction temperature.

  • Oxidation stabilized organic compositions
    Patent number: 3962124
    Abstract: The use of a condensation reaction product of (1) meta-cresol, para-cresol or a mixture of meta and para cresols, and (2) an aldehyde defined by R-CHO wherein R is hydrogen or an alkyl group having at least 1 carbon atom as an antioxidant in organic compositions.
