Joel R. Livingston, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for conversion of ethers to alcohols and olefins
    Patent number: 5403964
    Abstract: The present invention relates to enhanced process for converting certain ethers, such as sec-butyl ether and isopropyl ether to their corresponding reaction products in the presence of water. This may be accomplished by adding a rate enhancing surfactant, such as an anionic or cationic surfactant to a mixture of the ether and water, preferably least about 10.sup.-5 molar surfactant. Under those conditions the reaction shows an increase in reaction rate over the rate of the process wherein surfactant is not used.

  • Method for separating catalyst from a hydroformylation reaction product using alkylated ligands
    Patent number: 5395979
    Abstract: A catalyst for use in hydroformylation of olefins which comprises a Group VIII noble metal complexed with a phosphine ligand having at least one alkyl or aryl group bonded thereto, such as tris-4-propylphenyl phosphines and tris-4-octylphenyl phosphines. These and other triphenylphosphine catalysts can be separated from a crude reaction product of a noble metal-catalyzed hydroformylation reaction by contacting the crude reaction product with a dense polymeric, nonpolar membrane, preferably nonpolar polyolefin membranes.

  • Method for separating a water soluble noble metal catalyst from a noble metal catalyzed hydroformylation reaction
    Patent number: 5288818
    Abstract: A method for separating a water soluble Group VIII noble metal catalyst from the crude reaction product of a noble metal-catalyzed hydroformylation reaction run in aqueous solution, in an aqueous emulsion or as an aqueous suspension, the crude reaction product including an aqueous phase containing a water soluble Group VIII noble metal-ligand complex catalyst, and an organic phase containing unreacted olefin feed and an organic hydroformylation reaction product, which comprises: (a) contacting the crude reaction product with a hydrophobic membrane capable of allowing a substantial portion of the unreacted olefin feed and the organic hydroformylation reaction product to pass therethrough while retaining a substantial portion of the water soluble Group VIII noble metal-ligand complex catalyst; (b) removing unreacted olefin feed and organic hydroformylation reaction product which passes through the hydrophobic membrane as permeate; and (c) retaining the water soluble Group VIII noble metal-ligand complex catalys
