    摘要: This invention relates to a process for producing mono- and di- N-alkyl-dinitroalkylaniline or dinitroaniline derivative and particularly N-sec-butyl-4-tert-butyl-2,6-dinitroaniline by methylation of an alkylphenol or phenol derivative followed by nitration of the resulting acetic acid alkylanisole or anisole derivative which is followed by reaction with an amine. Acetic acid by-product produced during nitration is recycled by converting back to acetic anhydride.

    摘要: The invention provides a method for producing a molecule capable of undergoing reduction-oxidation when subjected to a voltage potential, the method comprising phosphorylating hydroquinone to create a first intermediate; rearranging the first intermediate to an aryl-bis- (phosphonate) thereby creating a second intermediate comprising phosphorous alkoxy groups; alkylating (e.g., methylating) the second intermediate; converting the alkoxy groups to halides; and substituting the halides to alkyl or aryl groups. Also provided is a system for preventing overcharge in a Lithium-ion battery, the method comprising a mixture of a redox shuttle with electrolyte in the battery such that the shuttle comprises between about 10 and about 20 weight percent of the mixture.
