Intshayelelo
I-2,4-i-Dichloropyrimidine i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-2,4-dichloropyrimidine:
Umgangatho:
- 2,4-Dichloropyrimidine yikristale engenambala kunye nevumba elimnandi.
- Inonyibiliko oluphantsi emanzini kunye nokunyibilika okuphezulu kwizinyibilikisi zendalo.
Sebenzisa:
- 2,4-Dichloropyrimidine sisibulala-zinambuzane esisetyenziswa ngokuqhelekileyo ukulawula ukhula kwizityalo.
Indlela:
- 2,4-Dichloropyrimidine inokulungiswa ngokuphendula i-pyrimidine ngegesi ye-chlorine. Dissolve pyrimidines in ferrous chloride kunye nobushushu kwiqondo lokushisa elifanelekileyo. Emva koko, ukusabela kwe-chlorination kuqhutyelwa ngokuzisa igesi ye-chlorine kwinkqubo yokusabela. Imveliso ekujoliswe kuyo ifunyenwe ngokusebenzisa i-crystallization kunye namanyathelo okucoca.
Ulwazi ngoKhuseleko:
- 2,4-Dichloropyrimidine yinto ecaphukisayo enokuthi ibe nefuthe elicaphukisayo emehlweni, ulusu kunye nenkqubo yokuphefumla.
- Xa usebenzisa i-2,4-dichloropyrimidine, nxiba iiglavu ezifanelekileyo zokukhusela, iiglasi, kunye neemaski zokuqinisekisa umoya omhle.
- Ngokukhawuleza emva kokuvezwa kwi-2,4-dichloropyrimidine, hlamba indawo echaphazelekayo ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza.
- Ngexesha lokugcinwa kunye nokuphatha, ukudibanisa ne-oxidants kunye ne-acids eqinile kufuneka kugwenywe ukuphepha ukuphendula okuyingozi.
