  • Dry detergent compositions
    Patent number: 5198145
    Abstract: Dry-blended detergent formulations are prepared by absorbing liquid surfactant on absorptive soda ash derived from the dehydration of sodium carbonate decahydrate.
    Type: Grant
    Filed: December 6, 1991
    Date of Patent: March 30, 1993
    Assignee: FMC Corporation
    Inventors: Walter Lobunez, David Goldstein
  • Use of tributoxyethylphosphate to control foam in the production of soda ash from trona
    Patent number: 4083939
    Abstract: Tributoxyethylphosphate is useful in controlling foam produced during the evaporative crystallization of calcined trona solutions. The chemical is effective at low concentrations, i.e. 1 to 30 ppm, and does not significantly alter the crystal habit of the sodium carbonate crystals.
    Type: Grant
    Filed: March 22, 1977
    Date of Patent: April 11, 1978
    Assignee: FMC Corporation
    Inventors: Walter Lobunez, Joseph M. Ilardi, R. Martin Wright, Allan P. Herring
  • Clarifier process for producing sodium carbonate
    Patent number: 3981686
    Abstract: Method for clarifying a carbonate process solution containing suspended insolubles which solution is used in the preparation of crystals selected from the group consisting of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate, and sodium carbonate monohydrate, which comprises dispersing in the carbonate process solution prior to crystallization a cationic flocculating agent comprising a substituted guar gum containing one quaternary ammonium group per 2 to 12 monosaccharide units to agglomerate the suspended insolubles so the suspended insolubles will readily settle out of the carbonate process solution.This invention relates to a process for clarifying a carbonate process solution used in the preparation of sodium bicarbonate, sodium sesquicarbonate, anhydrous sodium carbonate or sodium carbonate monohydrate crystals.
    Type: Grant
    Filed: October 24, 1974
    Date of Patent: September 21, 1976
    Assignee: Intermountain Research and Development Corporation
    Inventors: Walter Lobunez, Nam Kyun Kim, Eric Rau
  • Hydrochlorination of vinylidene chloride to produce methyl chloroform
    Patent number: 3981939
    Abstract: Vinylidene chloride is hydrochlorinated to methyl chloroform by passing the reactants into a suspension of a Friedel-Crafts carrier, preferably ferric chloride, suspended in a liquid medium selected from the group consisting of 1,1,2-trichloroethane and perchloroethylene.
    Type: Grant
    Filed: June 13, 1975
