Miscible with ether, diethylene glycol, acetone, carbon tetrachloride, benzene, chlorobenzene, kerosene and olive oil. It can react with hydroxyl-containing compounds, water, amines and compounds with active hydrogen atoms to generate carbamate, urea, semicarbazide, etc. Toluene is nitrated with mixed acid to obtain 2,4- and 2,6-dinitrotoluene, and then hydrogenated and reduced in the presence of nickel catalyst to obtain 2,4- and 2,6-diaminotoluene, which is then reacted with light in chlorobenzene solution. produced by gas reaction.
