Intshayelelo
I-4-nitrobenzyl utywala. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-4-nitrobenzyl alcohol:
Umgangatho:
- I-4-Nitrobenzyl yotywala yikristale engenambala eqinileyo kunye nevumba elimnandi elimnandi.
- Iyazinza kubushushu begumbi kunye noxinzelelo, kodwa inokubangela ugqabhuko-dubulo xa ibekwe kubushushu, kungcangcazelo, ukukhuhlana okanye ukudibana nezinye izinto.
- Inokunyibilika kwizinyibilikisi eziphilayo ezifana ne-alcohol, ii-ethers, kunye ne-chlorinated hydrocarbons, kwaye i-soluble kancinane emanzini.
Sebenzisa:
- I-4-nitrobenzyl yotywala yinto ebalulekileyo ephakathi kwi-organic synthesis kwaye isetyenziswa ngokubanzi ekulungiseleleni uluhlu lweekhemikhali.
Indlela:
- I-4-Nitrobenzyl yotywala inokufumaneka ngokunciphisa ukusabela kwe-p-nitrobenzene kunye ne-sodium hydroxide hydrate. Kukho iimeko ezininzi kunye neendlela zokuphendula, eziqhutyelwa ngokubanzi phantsi kweemeko ze-acidic okanye i-alkaline.
Ulwazi ngoKhuseleko:
I-4-Nitrobenzyl alcohol iyaqhuma kwaye kufuneka igcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.
- Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana neeglavu zaselebhu, iiglasi, kunye nempahla yokukhusela xa usebenza.
- Ukuthotyelwa okungqongqo kunye neendlela ezifanelekileyo zokusebenza ezikhuselekileyo kunye nemimiselo kufuneka kugcinwe ngexesha lokugcinwa kunye nokuphathwa.
- Nika ingqalelo ekukhuselweni kwendalo kwaye uthobele imimiselo nemigangatho efanelekileyo xa usebenzisa okanye ukulahla.
