    摘要: N-Alkyl-N'-phenyl-p-phenylenediamine particles, which are not easily broken during transportation or in a hopper and can be easily automatically metered, are prepared by a surface treating process wherein granulated N-alkyl-N'-phenyl-p-phenylenediamine particles are charged in a rotatable vessel and the vessel is then rotated at a temperature lower than the melting point of the N-alkyl-N'-phenyl-p-phenylenediamine, to cause the N-alkyl-N'-phenyl-p-phenylenediamine particles to freely flow.
