1.The chlorination of 2-amino-P-xylene (acetyl derivative) at the freezing point of glacial acetic yields a monochloro derivative. The location of the chlorine atom at position 5 was proved by converting the compound into 2,5 - dichloro ~ terephthalic acid.
2.A dichloro derjvative is obtained if the chlorination is carried out at a slightly higher temperature, 18~20 C.
3.A series of azo dyes was obtained by conpling the monochlo-ro-P-xylidine with phonol, resorcinol, thymol, 1-naphthol-5-sulfonic acid aud 1,8 - dihydroxy-3,6-disulfonic acid.
