Intshayelelo

I-2,4-i-Dinitroaniline yi-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- 2,4-Dinitroaniline yikristale etyheli enganyibilikiyo emanzini.

- Inendawo ephezulu yokutshisa kunye nokuqhushumba, kwaye ihlelwa njengento eqhumayo.

- Inokuncitshiswa kwi-amine compounds ngeziseko ezinamandla kunye ne-hydroxides.

 

Sebenzisa:

- I-2,4-Dinitroaniline isetyenziswa ngokubanzi kwishishini lemichiza njengento ekrwada kwiziqhushumbisi kunye neziqhushumbisi.

- Inokusetyenziswa kwakhona kwi-synthesis yedayi kunye ne-pigments, kunye ne-intermediate ebalulekileyo.

 

Indlela:

- Ukulungiswa kwe-2,4-dinitroaniline ngokuqhelekileyo kuqhutyelwa yi-nitrification. I-p-nitroaniline iphendula nge-nitric acid egxininisiweyo yokwenza i-2,4-dinitronitroaniline, kwaye emva koko iyanciphisa i-compound nge-asidi eqinile ukufumana i-2,4-dinitroaniline.

 

Ulwazi ngoKhuseleko:

- 2,4-Dinitroaniline yikhemikhali eqhuma kakhulu kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye nemithombo yobushushu.

- Umngcipheko wokungqubuzana, impembelelo, iintlantsi, kunye nokukhutshwa kwe-electrostatic kufuneka kulawulwe ngokungqongqo ngexesha lokuphatha, ukugcinwa, kunye nokuthutha.

- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglasi zokhuseleko kunye neeglavu zokhuselo xa usetyenziswa. Ukuba utyiwe, funa unyango ngokukhawuleza.

 

Njalo ulandele iinkqubo ezifanelekileyo zokhuseleko xa usebenzisa kunye nokuphatha i-2,4-dinitroaniline, kwaye uyisebenzise ngolwazi kunye nezilumkiso ezifanelekileyo.
