Intshayelelo
I-organic compound kunye ne-chemical formula C6H5ClN2O3.
Indalo:
-Imbonakalo: Imhlophe ukuya kolutyheli ukukhanya okuqinileyo
-Indawo yokunyibilika: 44-46°C
-Indawo yokubila: 262°C
-Inyibilika kuyo: utywala kunye ne-ether, ayinyibiliki emanzini
Sebenzisa:
yinto ephakathi ebalulekileyo, esetyenziswa ngokubanzi kwintsimi ye-organic synthesis. Ingasetyenziselwa ukudibanisa iintlobo ngeentlobo zeekhompawundi zebhayoloji ezisebenzayo, ezifana neziyobisi, idayi kunye nezitshabalalisi.
Indlela yokulungiselela:
I-Synthesis inokuqhutywa ngala manyathelo alandelayo:
1. I-2-Nitro-6-formylpyridine ifunyenwe ngokuphendula i-2-nitro-6-nitro-pyridine nge-asidi ye-sulfuric.
2. Ukusabela kwe-2-nitro-6-formylpyridine kunye ne-chloromethyl ether phantsi kwesenzo se-alkali senziwa.
3. Ukuhlanjululwa kunye namanyathelo e-crystallization ayenziwa ukufumana imveliso ecocekileyo.
Ulwazi ngoKhuseleko:
Into enobungozi enokuthi ibangele ukucaphuka kunye nokungaguquguquki ngenxa yokuvezwa okanye ukuphefumla. Xa usebenza, nxiba imilinganiselo yokukhusela efanelekileyo efana neeglavu, iiglasi kunye nempahla yokukhusela, kwaye uqinisekise ukuba umsebenzi wenziwa kwindawo engenamoya. Ngexesha lokugcinwa kunye nokuphatha, ukudibanisa kunye ne-oxidants enamandla kunye nezinto ezinokutsha kufuneka zigwenywe.
