Mawu Oyamba

2,5-Diaminotoluene ndi organic pawiri, zotsatirazi ndi mawu oyamba katundu, ntchito, kukonzekera njira ndi chitetezo zambiri 2,5-diaminotoluene:

 

Ubwino:

- Maonekedwe: 2,5-Diaminotoluene ndi ufa wonyezimira wonyezimira wachikasu.

- Kusungunuka: Amasungunuka pang'ono m'madzi, koma amasungunuka kwambiri mu zosungunulira za organic monga benzene ndi zosungunulira za mowa.

 

Gwiritsani ntchito:

- 2,5-Diaminotoluene ndi yofunika yapakatikati mu kaphatikizidwe organic, amene nthawi zambiri ntchito pokonza inki ndi utoto, makamaka pokonza kupanga ulusi khalidwe zipangizo.

 

Njira:

- Kukonzekera kwa 2,5-diaminotoluene kumatheka makamaka ndi kuchepetsa nitrotoluene. Nitrotoluene amayamba ndi ammonia kuti apange 2,5-dinitrotoluene, yomwe imachepetsedwa kukhala 2,5-diaminotoluene ndi kuchepetsa wothandizira monga sodium diene.

 

Zambiri Zachitetezo:

- 2,5-Diaminotoluene imakwiyitsa maso ndi khungu, choncho valani zida zoyenera zodzitetezera ndikupewa kukhudzana mukamagwiritsa ntchito.

- Mukamagwira ntchito, pewani kutulutsa fumbi kapena madzi ake ndikusunga mpweya wabwino.

- 2,5-Diaminotoluene iyenera kusungidwa kutali ndi kuyatsa ndi oxidizing agents, ndikusungidwa pamalo owuma, ozizira.

- Tsatirani njira zotetezeka zogwirira ntchito ndikutaya zinyalala moyenera mukamagwira kapena kusunga.
