  • Patent number: 4462931
    Abstract: Aqueous chemiluminescent systems are found to have improved chemiluminesence due to presence of surfactants in minor amounts.
    Type: Grant
    Filed: June 16, 1982
    Date of Patent: July 31, 1984
    Assignee: American Cyanamid Company
    Inventors: Martin L. Cohen, Frank J. Arthen, Jr., Shin-Shyong Tseng
  • Patent number: 4407743
    Abstract: N,N'-bis(trifluoromethylsulfonyl)oxamides are described with 2,2,2-trifluoroethyl, (ethoxycarbonyl)methyl, and [(phenylmethoxy)carbonyl]methyl substitution at the amido nitrogen atoms. These compounds, when used in chemiluminescent formulations, furnish superior light capacity and quantum efficiency. Preparation of the compounds and their use for chemiluminescence are described.
    Type: Grant
    Filed: March 19, 1982
    Date of Patent: October 4, 1983
    Assignee: American Cyanamid Company
    Inventor: Shin-Shyong Tseng
  • Patent number: 4338213
    Abstract: Quaternary salts of N,N'-bis(morpholinoalkyl)-N,N'-bis(trifluoromethylsulfonyl)oxamides and of N,N'-bis(pyridylalkyl)-N,N'-bis(trifluoromethylsulfonyl)oxamides are useful for generation of chemiluminescence by reaction with hydrogen peroxide in aqueous solvent.
    Type: Grant
    Filed: April 13, 1981
    Date of Patent: July 6, 1982
    Assignee: American Cyanamid Company
    Inventors: Shin-Shyong Tseng, Michael M. Rauhut
  • Patent number: 4288592
    Abstract: There is provided a process for preparing amides which comprises reacting an amine, or an amide, and an acid halide, or anhydride, in suitable molecular proportions, in an inert organic diluent, in the presence of an effective amount of a molecular sieve, until the reaction is completed, separating the molecular sieve, and recovering the amide from the organic mother liquor.
    Type: Grant
    Filed: April 30, 1979
    Date of Patent: September 8, 1981
    Assignee: American Cyanamid Company
    Inventors: Michael M. Rauhut, Shin-Shyong Tseng
  • Patent number: 4282357
    Abstract: Quaternary salts of N,N'-bis(morpholinoalkyl)-N,N'-bis(trifluoromethylsulfonyl)oxamides and of N,N'-bis(pyridylalkyl)-N,N'-bis(trifluoromethylsulfonyl)oxamides are useful for generation of chemiluminescence by reaction with hydrogen peroxide in aqueous solvent.
    Type: Grant
    Filed: February 19, 1980
    Date of Patent: August 4, 1981
    Assignee: American Cyanamid Company
    Inventors: Shin-Shyong Tseng, Michael M. Rauhut
  • Patent number: 4226738
    Abstract: N,N'-bis(trifluoromethylsulfonyl)oxamides are described with a number of variations by substitution at the amido nitrogen atoms. These compounds when used in chemiluminescent formulations will furnish superior light intensity and quantum efficiency. Preparation of compounds and their use for chemiluminescence are described.
