The development of new perspective method of the production of rubbers stabilizer on the basis of 4-aminodiphenylamine
A new promising method for the preparation of N-isopropyl-N'-phenyl-p-phenylenediamine consisting of reacting of 4-aminodiphenylamine with isopropyl bromide in an ethylene glycol medium is proposed. The technological parameters of the process are determined. Reaction byproducts are identified. The compounds obtained are characterized by the gas chromatography method, their reaction composition is determined. The reaction equations are shown.
