Nhanganyaya

Benzidine (inozivikanwawo se diphenylamine) ndeye organic compound. Inotevera sumo kune hunhu hwayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:

 

Hunhu:

- Chitarisiko: Benzidine ichena kusvika kuchiedza yero crystalline yakasimba.

- Solubility: isinganyungudika mumvura, inonyungudika mune organic solvents senge madoro, ethers, nezvimwe.

- Chiratidzo: I electrophile ine zvinhu zve electrophilic substitution reaction.

 

Shandisa:

- Benzidine inoshandiswa zvakanyanya mumunda we organic synthesis. Inogona kushandiswa seyakagadzirwa uye yepakati pemakemikari emakemikari akadai sedhayi, pigment, mapurasitiki, nezvimwe.

 

Nzira:

- Benzidine yagara yakagadzirirwa ne dinitrobiphenyl kuderedza, kubviswa kwemwaranzi ye haloaniline, nezvimwe.

- Nzira dzemazuva ano dzekugadzirira dzinosanganisira organic synthesis yeanonhuwirira amines, sekuita kwe substrate diphenyl ether ine amino alkanes.

 

Zvekuchengetedza

- Benzidine ine chepfu uye inogona kukonzera kutsamwa uye kukuvadza kumuviri wemunhu.

- Paunenge uchibata benzidine, kutarisirwa kunofanirwa kutorwa kudzivirira kubata ganda uye kufema, uye zvekudzivirira zvakaita semagirovhosi, magirazi ekudzivirira, uye masks ekudzivirira zvinofanirwa kupfekwa kana zvichidikanwa.

- Kana benzidine ikasangana neganda kana maziso, inofanira kugezwa nekukurumidza nemvura yakawanda.

- Paunenge uchichengeta uye uchishandisa benzidine, chenjerera kudzivirira kusangana ne organic zvinhu uye oxidants kudzivirira moto kana kuputika.
