Mawu Oyamba

Azodicarboxamide (N,N'-dimethyl-N,N'-dinitrosoglylamide) ndi cholimba cha crystalline chopanda mtundu chokhala ndi zinthu zapadera komanso ntchito zosiyanasiyana.

 

Ubwino:

Azodicarboxamide ndi krustalo wopanda mtundu kutentha firiji, sungunuka mu zidulo, alkalis ndi zosungunulira organic, ndipo ali solubility wabwino.

Imatha kutenthedwa kapena kuwombedwa ndikuphulika, ndipo imagawidwa ngati yophulika.

Azodicarboxymide imakhala ndi ma oxidizing amphamvu ndipo imatha kuchitapo kanthu mwamphamvu ndi zinthu zoyaka komanso zotsekemera mosavuta.

 

Gwiritsani ntchito:

Azodicarboxamide imagwiritsidwa ntchito kwambiri pakupanga mankhwala ndipo ndi yofunika kwambiri komanso yapakatikati pamachitidwe ambiri a organic synthesis.

Amagwiritsidwa ntchito ngati zopangira zopangira utoto mumakampani opanga utoto.

 

Njira:

Kukonzekera njira za azodicarbonamide makamaka motere:

Zimapangidwa ndi zomwe nitrous acid ndi dimethylurea.

Amapangidwa ndi zomwe sungunuka dimethylurea ndi dimethylurea yoyambitsidwa ndi nitric acid.

 

Zambiri Zachitetezo:

Azodicarboxamide ndi yophulika kwambiri ndipo iyenera kusungidwa kutali ndi kuyatsa, kukangana, kutentha ndi zinthu zina zoyaka moto.

Magolovesi oteteza oyenerera, magalasi, ndi masks ayenera kuvala mukamagwiritsa ntchito azodicarbonamide.

Pewani kukhudzana ndi ma okosijeni ndi zoyaka pamene mukugwira ntchito.

Azodicarbonamide iyenera kusungidwa pamalo otsekedwa, ozizira, opanda mpweya wabwino kutali ndi dzuwa.
