Inkcazo
Iimathiriyeli ekrwada ye-G emnyama ngokuthe ngqo yi-m-phenylenediamine, i-p-nitroaniline kunye ne-H acid.Okokuqala, i-p-nitroaniline i-diazotized, kwaye emva koko ukudibanisa kokuqala kunye ne-H acid kuqhutyelwa kwindawo ene-acidic engenamandla.Emva koko ukudibanisa okwesibini kunye ne-H acid kwenziwa phantsi kweemeko ezibuthathaka ezisisiseko.Emva koko sebenzisa i-alkali sulfide ukunciphisa i-nitro, kunye ne-diazotization, kunye ne-m-phenylenediamine kwimveliso yesithathu yokudibanisa.Emva kwe-salting ngaphandle, ukucoca, ukomisa, ukugaya umkhiqizo ogqityiweyo.
Umlinganiswa wemveliso
