Uhlobo lwe-N,N-dimethylaniline: alunambala ukuya koluphuzi olukhanyayo okanye ulwelo olunamafutha olumdaka kancinci, olunevumba elibi.

I-N,N-dimethylaniline (DMBA) inoluhlu olubanzi lokusetyenziswa, ikakhulu kuquka ezi zinto zilandelayo:

‌1. Iidayi eziphakathi
I-DMBA yindawo ebalulekileyo yokwenza i-vanillin, idayi ze-azo, idayi ze-triphenylmethane, njl.

2. Izinyibilikisi kunye neziqinisi
Ingasetyenziswa njengesinyibilikisi kunye nesiqinisi, idlala indima ekunyibilikiseni nasekuzinziseni ezinye izinto zeekhemikhali kwimveliso yeekhemikhali.

3. Ii-reagents zohlalutyo
I-DMBA ingasetyenziswa njenge-analytical reagent kwaye inexabiso lokusetyenziswa kuhlalutyo lweekhemikhali kunye novavanyo.

Kufuneka kuqatshelwe ukuba nangona i-DMBA isetyenziswa kakhulu kwishishini leekhemikhali, ikwathathwa njengesifo somhlaza, ngoko ke kufuneka kuthathwe unonophelo olukhethekileyo ngexesha lokusetyenziswa nokugcinwa kwayo, kwaye kufuneka kulandelwe imigaqo efanelekileyo yokhuseleko.

Iimpawu ze-N,N-dimethylaniline ziquka ikakhulu ezi zinto zilandelayo:

‌1. Iimpawu zomzimba
Inkangeleko: Akukho mbala ukuya kumthubi okhanyayo okanye ulwelo olunamafutha olumdaka kancinci. Ivumba: Inevumba elibi.
Ukunyibilika: Iyanyibilika kwiintlobo ngeentlobo zezinto eziphilayo ezifana ne-ethanol, i-ether, i-chloroform, i-benzene, kwaye iyanyibilika kancinci emanzini.
Iqondo lokubila kunye neqondo lokunyibilika: Iqondo lokubila limalunga ne-193.1℃ ukuya kwi-193.5℃, kwaye iqondo lokunyibilika liphantsi, phakathi kwe-1.5-2.5°C.

II. Iimpawu zekhemikhali
Ukutsha: Le nto inokutsha kwaye iya kutsha xa ivezwa kumlilo ovulekileyo. Umphunga nomoya zinokwenza umxube oqhumayo.
Ubuthi: Yinto enobungozi kakhulu enokuthi ifunxwe lusu ize ibangele ubuthi. Inobungozi obufana nobe-aniline.
Uzinzo: Ingcoliswa lula emoyeni okanye elangeni, nto leyo eyenza umbala ube mnyama.
I-Reactivity: Ingasabela kwiikhemikhali ezahlukeneyo, ezifana ne-picric acid, i-alkyl halides, ii-acylating agents, njl.

Ezi mpawu zifuna ingqalelo ekhethekileyo kukhuseleko ngexesha lokugcina, ukuthuthwa nokusetyenziswa kwe-N,N-dimethylaniline, kwaye zilandela iinkqubo ezifanelekileyo zokusebenza.
