Nhanganyaya

Benzoazobenzoazo-2-naphthol inonyanya kushandiswa sedhayi mumaindasitiri akadai semachira, ingi nemapurasitiki. Inogona kushandiswa kudhaya zvinhu zvefibrous zvakadai sekotoni, yerineni, mvere dzemakwai, nezvimwewo. Kugadzikana kwayo kwemavara kwakanaka uye hakusi nyore kupera, saka inoshandiswa zvakanyanya mumunda wemicheka.

 

Nzira yekugadzira benzoazobenzobenzo-azo-2-naphthol inowanzogadzirwa neazo reaction. Aniline inotanga kubatwa ne nitric acid kuti igadzire nitroaniline, yozoitwa nenaphtholl kuti igadzire chigadzirwa chakananga, benzoazobenzo-azo-2-naphthol.

 

Ruzivo rwezvekuchengetedza nezve benzoazobenzenezo-2-naphthol, chinhu chinopisa uye chinoda kuchengetwa munzvimbo inotonhorera, ine mhepo inofefetera, kure nekunobva moto uye tembiricha yepamusoro. Midziyo yekuzvidzivirira yakafanira senge magurovhosi erabhoritari, magirazi ekuchengetedza, uye majasi erabhoritari anofanirwa kupfekwa panguva yekushanda. Sezvo iri kemikari, maitiro ekuchengetedza akakodzera uye maitiro ekurasa tsvina anofanirwa kuteverwa.
