2-Chloro-3-picoline (CAS# 18368-76-8) Intshayelelo
-Imbonakalo: Ulwelo olungenambala okanye olumthubi olukhanyayo.
Ubunzima bemolekyuli obunxulumeneyo: 129.57.
-Indawo yokunyibilika:-30 °C.
-Indawo yokubila: 169-171 ° C.
-Ubuninzi: malunga ne-1.158g/cm³.
-Ukunyibilika: Inyibilika kwi-ether anhydrous, chloroform, benzene kunye ne-ethanol.Sebenzisa:
-2-chloroo-3-methylpyridine ingasetyenziselwa njengento ebalulekileyo ephakathi kwi-organic synthesis kwaye isetyenziswe kwi-synthesis yezinye izinto eziphilayo.
-Ingasetyenziswa njengezinto ezibonakalayo kwintsimi ye-pesticides kunye namayeza.
Indlela:
Ukulungiswa kwe-2-chloro-3-methylpyridine ngokuqhelekileyo kuqhutyelwa ngale ndlela ilandelayo:
-Electrophilic substitution reaction of pyridine, unyango lwe-pyridine nge-chloroacetic acid kunye ne-ferrous chloride ukuvelisa i-chloropyridine.
-Emva koko uphendule nge-methyl alcohol kunye ne-hydrochloric acid ukuvelisa i-2-chloro-3-methylpyriridine.
Ulwazi ngoKhuseleko:
- I-2-chloro-3-methylpyridine yi-organic compound. Kufuneka kuthatyathwe amanyathelo afanelekileyo okhuseleko xa uphathwa, njengokunxiba iiglavu zokhuselo neendondo, kunye nokugcina umoya omhle.
-Kuphephe ukudibana nolusu kunye namehlo. Ukuba ukudibana kwenzeka, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
-Gcina kude namadangatye avulekileyo kunye nemithombo yobushushu ngexesha lokugcinwa kunye nokusetyenziswa ukukhusela iigesi eziyingozi.
