Selelekela

2-Aminopyrazine ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:

 

Boleng:

Ponahalo: 2-aminopyrazine ke kristale e tiileng e se nang 'mala.

Solubility: 2-aminopyrazine e na le monyebe o motle ka metsing, hape e ka qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le chloroform.

Lintho tsa lik'hemik'hale: 2-aminopyrazine ke ntho e nang le alkaline e sebetsanang habonolo le asiti ho etsa matsoai. E ka boela ea etsa liphetoho tsa lik'hemik'hale tse kang electrophilic substitution reactions.

 

Sebelisa:

Temo: 2-Aminopyrazine e ka sebelisoa e le motsoako oa chefo e bolaeang likokoanyana joalo ka li-fungicides, herbicides, le lilaoli tsa kholo ea limela.

 

Mokhoa:

Ho na le mekhoa e mengata ea ho lokisa 2-aminopyrazine, 'me e sebelisoang hangata ke e latelang:

Pyrazine le ammonia reaction reaction: pyrazine le ammonia li koaheloa 'me li itšoara ka mocheso o phahameng, ebe li hloekisoa ka ho felloa ke metsi le crystallization ho fumana 2-aminopyrazine.

Ho lokisoa ha hydrogenation ea pyrrolidone: pyrrolidone e hydrogenated le ammonia ka pel'a mokelikeli ho fumana 2-aminopyrazine.

 

Lintlha tsa Tšireletseho:

2-Aminopyrazine ke motsoako oa lintho tse phelang, 'me tlhokomelo e lokela ho lefshoa ho sireletsa mollo le ho phatloha ha ho sebelisoa le ho boloka.

Ha u kopana le 2-aminopyrazine, ho kopana ka ho toba le letlalo le ho hema ka khase ea eona ho lokela ho qojoa. Nakong ea ts'ebeliso, lisebelisoa tse khethehileng tsa ho itšireletsa li lokela ho apesoa.

Haeba u ikutloa u sa phutholoha ka mor'a ho metsa kapa ho kopana le letlalo, batla thuso ea bongaka hang-hang 'me u tlise setshelo le leibole ea motsoako.

Ha u sebetsana le 2-aminopyrazine, mekhoa e nepahetseng ea tšireletso e lokela ho lateloa, 'me litšila li lokela ho lahloa hantle.
