  • Process for the isolation and removal of unwanted water from a chemical reaction
    Patent number: 5917078
    Abstract: An improved continuous process for removal of water from a process for producing organic carbonates, particularly diphenyl carbonate, by treating the water containing products of the reaction with a condensable stripping agent in a gaseous state and recycling a major portion of the water poor reaction products back to the reaction for producing the organic carbonate. The stripping agent, preferably n-pentane, is condensed upon removal from the water stripping step and recycled back to the water stripping step.
    Type: Grant
    Filed: September 25, 1998
    Date of Patent: June 29, 1999
    Assignee: General Electric Company
    Inventors: Richard A. Battista, Francis S. Lo, Robert L. Tatterson
  • Magnesium-containing catalyst activated under vacuum, in nitrogen, or in air, and use in an ortho-alkylation process
    Patent number: 4851591
    Abstract: A catalyst precursor comprising a magnesium compound or material, optionally also containing other metal compounds, is activated for use by calcining at an elevated temperature in the presence of air or nitrogen, or under vacuum. The active catalyst which results may be used in processes for the ortho-alkylation of phenolic compounds, with good yields of and selectivity to the ortho-alkylated end product.
    Type: Grant
    Filed: December 16, 1987
    Date of Patent: July 25, 1989
    Assignee: General Electric Company
    Inventors: Richard A. Battista, James G. Bennett, Jr., John J. Kokoszka, Freddie L. Tungate
  • Catalyst derived from mixture of manganese hydroxide and magnesium-containing material, and method of use in ortho-alkylation of phenols
    Patent number: 4661638
    Abstract: A catalyst precursor prepared by precipitating manganese hydroxide from caustic solution and then mixing the precipitate with a magnesium-containing material is described. The catalyst precursor can be calcined to an active form, and the resulting catalyst can be used to effect or facilitate the ortho-alkylation of phenolic compounds in vapor phase reactions. Superiority of performance is demonstrated with respect to a catalyst derived from a precursor in which manganese hydroxide is precipitated (sometimes referred to as "co-precipitation") in the presence of a magnesium compound, rather than formed separately.

  • Catalytic process for preparation of ortho-alkylated phenols
    Patent number: 4528407
    Abstract: An improved catalytic process for selectively ortho-alkylating a phenolic compound which comprises reacting a phenolic compound with an alcohol, optionally in the presence of water, and a catalyst composite consisting essentially of the calcination residue obtained from heating an admixture of magnesium carbonate and/or magnesium hydroxide and a manganese compound.

  • Method of preparing a magnesium-manganese catalyst precursor and catalyst
    Patent number: 4458031
    Abstract: Disclosed are a catalyst comprising a magnesium-containing moiety, a method for preparing the catalyst, and a process for the vapor phase ortho-alkylation of phenols in the presence of the catalyst.
