  • Method for producing 2,3-dimethyl-2,3-dinitrobutane and product thereby
    Patent number: 6911328
    Abstract: The present invention includes a method for producing 2,3-dimethyl-2,3-dinitrobutane, particularly in high yields, using a peroxidase enzyme site and reacting propane-2-nitronate at the enzyme under appropriate conditions. Peroxidases such as chloroperoxidase, soybean peroxidase and horseradish peroxidase are used. High yields include those amounts that increasingly aid in the manufacture of commercial quantities of 2,3-dimethyl-2,3-dinitrobutane.
    Type: Grant

  • Application of germination solution improved efficacy of biological decontamination
    Publication number: 20030175318
    Abstract: Decontamination of biological spores occurs by applying a germination solution for spores containing calcium ions, preferably calcium chloride, and dipicolinic acid in combination with a decontaminant. The germination composition may include water and a surfactant. The germination solution allows for lower concentrations of select decontaminants to be effectively used against spore contamination. The germination composition may be applied prior to, concurrently, or sequentially with repeated applications of the decontaminant.
