Mawu Oyamba

3,4-Dichloronitrobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:

Ubwino:

- 3,4-Dichloronitrobenzene ndi kristalo wopanda mtundu kapena wachikasu wonyezimira wokhala ndi fungo lamphamvu la fumigation.

- Sasungunuke m'madzi kutentha kwachipinda, koma amasungunuka muzosungunulira zambiri za organic.

Gwiritsani ntchito:

- 3,4-Dichloronitrobenzene angagwiritsidwe ntchito ngati reagent mankhwala monga gawo lapansi kwa nitrosylation reactions.

- Itha kugwiritsidwanso ntchito ngati kalambulabwalo wa kaphatikizidwe kazinthu zina za organic, monga glyphosate, herbicide.

Njira:

- 3,4-Dichloronitrobenzene nthawi zambiri amakonzedwa ndi chlorination wa nitrobenzene. Njira yeniyeni yokonzekera ingagwiritse ntchito kusakaniza kwa sodium nitrite ndi nitric acid, ndikuchitapo ndi benzene pazochitika zoyenera. Pambuyo pochita, chandamalecho chimatsukidwa ndi crystallization ndi masitepe ena.

Zambiri Zachitetezo:

- 3,4-Dichloronitrobenzene ndi poizoni ndipo akhoza kuvulaza thanzi la munthu. Kuwonekera, kutulutsa mpweya, kapena kumwa mankhwalawa kungayambitse kuyabwa kwa maso, kupuma ndi khungu.

- Chigawochi chiyenera kusungidwa pamalo abwino mpweya wabwino, owuma, ozizira, kutali ndi zoyaka ndi okosijeni.

Zam'mbuyo: 2,5-Dichloronitrobenzene(CAS#89-61-2)

Ena: 2,4-Dinitroaniline(CAS#97-02-9)
