  • Methods of using select Schiff base compounds for chemical agent detoxification
    Patent number: 10384090
    Abstract: A method of using select Schiff base compounds for chemical agent detoxification. The method including applying a compound to the contaminated substrate. The compound includes an imine having at least one Schiff base nitrogen and an alkyl substituent or an aryl substituent having an electron acceptor. The at least one Schiff base nitrogen is spaced away from the electron acceptor by a distance ranging from about 200 pm to about 1000 pm. The substrate and the compound are dried. The at least one Schiff base nitrogen of the compound promotes a nucleophilic attack on an electrophilic site of the toxic chemical agent.
