Intshayelelo
I-2-Hydroxy-3-nitrobenzaldehyde yikhompawundi ephilayo eyaziwa ngokuba yi-3-nitro-2-hydroxybenzaldehyde. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: Ikristale etyheli eqinileyo.
Sebenzisa:
- Ingasetyenziselwa njengento yokuqala yokwenziwa kwezinye izinto eziphilayo, ezifana ne-antibiotics yokwenziwa kunye nedayi.
Indlela:
- Ukulungiswa kwe-2-hydroxy-3-nitrobenzaldehyde inokufumaneka nge-nitrification ye-parabentaldehyde.
Ngokuqhelekileyo phambi kwe-agent ye-nitrifying, i-benzaldehyde ixutywe ngokukhawuleza kunye ne-nitric acid, kwaye imveliso efunyenwe emva kokuphendula i-2-hydroxy-3-nitrobenzaldehyde.
- Inkqubo yokudibanisa kufuneka yenziwe phantsi kweemeko zovavanyo ezifanelekileyo ukuqinisekisa ukhuseleko kunye nezivuno eziphezulu.
Ulwazi ngoKhuseleko:
- I-2-Hydroxy-3-nitrobenzaldehyde yinto eyityhefu enokutsha.
- Landela izenzo zokhuseleko lwelabhoratri yeekhemikhali kwaye unxibe iiglavu ezifanelekileyo zokukhusela, iiglasi, kunye needyasi zelebhu ngexesha lokusebenza.
Kulumkele ukudibana nolusu, amehlo, kunye nempahla, kwaye unakekele ukuthintela ukuphefumla umgubo okanye iigesi zazo.
