Selelekela

3,5-Dichloropyridine ke motsoako oa lintho tse phelang. Ke mokelikeli o se nang 'mala o nang le monko o matla o hlabang.

3,5-dichloropyridine e boetse e arabela habonolo ka sodium hydroxide ho etsa khase e chefo ea hydrogen chloride.

 

3,5-Dichloropyridine e na le mefuta e mengata ea likopo ts'ebetsong ea organic synthesis. E ka sebelisoa e le moemeli oa bohlokoa oa ho fokotseha bakeng sa motsoako oa li-ketone.

 

Ho na le mekhoa e mengata ea ho lokisa 3,5-dichloropyridine. Mokhoa o tloaelehileng o fumanoa ka ho arabela pyridine ka khase ea chlorine. Mehato e tobileng e kenyelletsa: ho kenngoa ha khase ea chlorine ka tharollo e nang le pyridine tlas'a maemo a loketseng a karabelo. Kamora karabelo, sehlahisoa sa 3,5-dichloropyridine se ile sa hloekisoa ka distillation.

 

Ha o sebelisa 3,5-dichloropyridine, mekhoa e ts'oanang ea ts'ireletso e lokela ho lateloa mme lisebelisoa tsa ts'ireletso li lokela ho apesoa. Qoba ho kopana le letlalo, mahlo le lera la mucous. Tlhokomelo e lokela ho nkoa ho e thibela ho sebetsana le lik'hemik'hale tse ling nakong ea ho tšoara le ho boloka ho qoba likotsi. Nakong ea polokelo, 3,5-dichloropyridine e lokela ho bolokoa ka har'a sets'oants'o se se nang moea le ho beoa sebakeng se phodileng, se omileng.
