Isingeniso

I-2-Chloropyridine-6-carboxylic acid, eyaziwa nangokuthi i-2-Chloro-6-pyridinecarboxylic acid.

 

Ikhwalithi:

I-2-Chloropyridine-6-carboxylic acid iyikristale eqinile emhlophe enephunga elikhethekile. Iyancibilika otshwaleni, i-ketone nezincibilikisi ze-ether futhi inyibilika kancane emanzini.

 

Sebenzisa:

I-2-Chloropyridine-6-carboxylic acid ingasetshenziswa njengendawo ephakathi ekuhlanganisweni kwezinhlanganisela eziphilayo.

 

Indlela:

Ukulungiswa kwe-2-chloropyridine-6-carboxylic acid kungatholakala ngokuphendula i-2-chloropyridine nge-chlorine phambi kwe-catalyst yotshwala. Indlela eqondile yokulungiselela imi kanje:

Ngaphansi kwesimo sokushisa okungapheli, i-2-chloropyridine isabela nge-chlorine, futhi umkhiqizo (2-chloropyridine-6-carboxylic acid) utholakala ngemuva kokusabela.

 

Ulwazi Lokuphepha:

I-2-Chloropyridine-6-carboxylic acid ngokuvamile iphephe kakhulu ngaphansi kwezimo ezijwayelekile zokusebenza, kodwa kufanele kuthathwe izinyathelo zokuphepha. Ngesikhathi sokusebenzisa, gwema ukuthintana nesikhumba namehlo, futhi uqinisekise ukuthi ukuhlinzwa kwenziwa endaweni enomoya omuhle. Uma kwenzeka ingozi, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezempilo.

Uma usebenzisa futhi uphatha amakhemikhali, kubalulekile ukulandela izinqubo ezifanele zaselabhorethri kanye nezinyathelo zokuzivikela komuntu siqu ukuze kuqinisekiswe ukuphepha nokuvikelwa kwemvelo.
