  • Process for preparing isopropylphenyl/phenyl phosphate
    Patent number: 4351780
    Abstract: Monoisopropylphenyl/phenyl phosphate containing mixtures are prepared by, (1) alkylating phenol with propylene to C.sub.3 /.phi. ratio of less than 0.30 with a p-toluene sulfonic acid catalyst, (2) removing unreacted phenol as distillate to yield a distilland having a C.sub.3 /.phi. ratio above 0.3 and thereafter, (3) phosphorylating the distilland to yield a triaryl phosphate mixture having a reduced 2,6-diisopropylphenyl phosphate content.
    Type: Grant
    Filed: December 9, 1980
    Date of Patent: September 28, 1982
    Assignee: Stauffer Chemical Company
    Inventors: Silvio L. Giolito, Stanley B. Mirviss
  • Vinyl chloride compositions plasticized with meta-tertiary-butylphenyl diphenyl phosphate
    Patent number: 4280945
    Abstract: Tertiary-butylphenyl diphenyl phosphate esters in which the nominal molar ratio of tertiary-butyl radicals to phenyl radicals ranges from about 1:5 to about 1:2, the meta-tertiary-butylphenyl content ranges from about 25% to about 100% and the ortho-tertiary-butylphenyl content is less than about 50% are highly effective plasticizers for vinyl chloride polymer compositions.
    Type: Grant
    Filed: November 5, 1979
    Date of Patent: July 28, 1981
    Assignee: Stauffer Chemical Company
    Inventors: Stanley B. Mirviss, Silvio L. Giolito
  • Process for manufacturing substantially pure dialkyl phosphorochloridothionate
    Patent number: 4185053
    Abstract: A process for producing in high yields a substantially pure dialkyl phosphorochloridothionates. The process comprises chlorinating bis(phosphorothioic) sulfides, thioic acids, or salts thereof, distilling the reaction mixtures, contacting the distillate with a thioic acid or salt thereof, contacting the mixture with water and distilling the organic material after the water contacting.
    Type: Grant
    Filed: October 3, 1977
    Date of Patent: January 22, 1980
    Assignee: Stauffer Chemical Company
    Inventors: Stanley B. Mirviss, Thomas M. Von Lehman
  • Preparation of meta-alkylphenols
    Patent number: 4103096
    Abstract: Meta-alkylphenols are prepared by the isomerization of nonmeta-alkylphenols in the presence of trifluoromethane sulfonic acid. Ortho-isomer-containing alkylphenols are isomerized to increase their meta-isomer content and reduce their ortho-isomer content.
    Type: Grant
    Filed: October 13, 1977
    Date of Patent: July 25, 1978
    Assignee: Stauffer Chemical Company
    Inventors: Silvio L. Giolito, Stanley B. Mirviss
  • Color improvement of phosphate esters
    Patent number: 3931363
    Abstract: A method for decolorizing and stabilizing alkylphenyl esters of phosphoric acid which comprises contacting the esters with an effective amount of a triorganoaluminum or organoaluminum hydride for a sufficient length of time to decolorize and stabilize the esters against subsequent color formation.
    Type: Grant
    Filed: December 23, 1974
    Date of Patent: January 6, 1976
    Assignee: Stauffer Chemical Company
    Inventors: Silvio L. Giolito, Stanley B. Mirviss
  • Color improvement of phosphate esters
    Patent number: 3931365
    Abstract: A method for decolorizing and stabilizing alkylphenyl esters of phosphoric acid which comprises contacting the esters with an effective amount of a water soluble salt of a reduced form of sulfur for a sufficient length of time to decolorize and stabilize the esters against subsequent color formation.
