Ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C6H5ClN2O3.
Tlhaho:
-Ponahalo: Bosoeu ho isa ho bosehla bo bobebe bo tiileng
- Sebaka se qhibilihang: 44-46°C
- Sebaka se belang: 262°C
E qhibiliha ka har'a: joala le ether, ha e qhibilihe ka metsing
Sebelisa:
ke ea bohlokoa lipakeng, e sebelisoang haholo tšimong ea organic synthesis. E ka sebelisoa ho kopanya mefuta e fapaneng ea metsoako ea bioloji, joalo ka lithethefatsi, dae le chefo e bolaeang likokoanyana.
Mokhoa oa ho itokisa:
Synthesis e ka etsoa ka mehato e latelang:
1. 2-Nitro-6-formylpyridine e fumanoe ka ho arabela 2-nitro-6-nitro-pyridine ka sulfuric acid.
2. Karabelo ea 2-nitro-6-formylpyridine le chloromethyl ether tlas'a ketso ea alkali e hlahisoa.
3. Mehato ea ho hloekisa le crystallization e ile ea etsoa ho fumana sehlahisoa se hloekileng.
Lintlha tsa Tšireletseho:
Ntho e kotsi e ka bakang ho teneha le ho hanana le mmele ka ho pepesehela kapa ho hema. Ha u sebetsa, apara mehato e nepahetseng ea tšireletso e kang liatlana, likhalase le liaparo tse sireletsang, 'me u netefatse hore ts'ebetso e etsoa sebakeng se nang le moea o motle. Nakong ea ho boloka le ho tšoara, ho kopana le li-oxidants tse matla le lisebelisoa tse tukang li lokela ho qojoa.
