o-Phenylenediamine condenses with ketones and aldehydes to give rise to a variety of useful products. Its reactions with carboxylic acids and their derivatives produce benzimidazoles. The herbicides benomyl and fuberidazole are made in this manner. Thiophanate-methyl is another herbicide produced from o-phenylenediamine. Quinoxalinedione may be prepared by condensation of o-phenylenediamine with dimethyl oxalate. … WebDec 1, 2011 · Electrochemical characterization of the carbon derivatives demonstrated that the decrease in aniline concentration during the synthesis of the precursor cryogels led to higher gravimetric capacitance for corresponding carbonized materials. These materials can potentially be used for energy storage applications.
