Nhanganyaya
Diphenylamine inhengo yemubatanidzwa. Inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza diphenylamine:
Hunhu:
Chitarisiko: Diphenylamine ikristaro chena yakasimba ine kunhuhwirira kweamine isina simba.
Solubility: Inonyungudika muorganic solvents senge ethanol, benzene uye methylene chloride pakamuri tembiricha, asi isinganyungudika mumvura.
Kugadzikana: Diphenylamine haina kugadzikana pasi pemamiriro akajairwa, ichaita oxidize mumhepo, uye inogona kuburitsa magasi ane muchetura.
Shandisa:
Indasitiri yedhayi uye pigment: Diphenylamine inoshandiswa zvakanyanya mukugadzirwa kwedhayi uye pigment, iyo inogona kushandiswa kudhaya fiber, dehwe nemapurasitiki, nezvimwe.
Chemical research: Diphenylamine chinhu chakakosha reagent muorganic synthesis uye inowanzo shandiswa kugadzira kabhoni-kabhoni uye kabhoni-nitrogen zvisungo.
Nzira:
Nzira yekugadzirira yakajairika ye diphenylamine inowanikwa neamino dehydrogenation reaction yeaniline. Gasi-phase catalysts kana palladium catalysts inowanzo shandiswa kufambisa maitiro.
Zvekuchengetedza
Kufema, kupinza, kana kubata ganda kunogona kukonzera kusvotwa uye kunoparadza maziso.
Panguva yekushandiswa uye kutakura, kusangana neganda nemeso kunofanira kudziviswa, uye mamiriro ekufema akakodzera anofanirwa kuverengerwa.
Diphenylamine inogona kukonzera kenza uye maitiro ekuchengetedza akakodzera anofanirwa kuteverwa uye mirau inoteedzerwa. Midziyo yekudzivirira yakakodzera inofanirwa kupfekwa kana ichishandiswa uye ichishandiswa murabhoritari.
Izvo zviri pamusoro apa ishumo pfupi yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza diphenylamine. Kuti uwane rumwe ruzivo rwakadzama, ndapota bvunza mabhuku akakodzera kana bvunza nyanzvi.
