2-Chloro-3-picoline (CAS# 18368-76-8) Isingeniso

I-2-chloro-3-methylpyriridine iyinhlanganisela ye-organic ene-chemical formula C6H6ClN. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:Imvelo:
-Ukubukeka: Uketshezi oluphuzi olungenambala noma olukhanyayo.
-isisindo samangqamuzana esihlobene: 129.57.
-Indawo yokuncibilika: -30 ° C.
-Indawo yokubilisa: 169-171 ° C.
-Ukuminyana: mayelana ne-1.158g/cm³.
-Ukunyibilika: Kuncibilika ku-ether anhydrous, chloroform, benzene ne-ethanol.Sebenzisa:
-2-chloroo-3-methylpyridine ingasetshenziswa njengendawo ebalulekile ekuhlanganiseni kwezinto eziphilayo futhi isetshenziswe ekuhlanganiseni ezinye izinhlanganisela eziphilayo.
-Ingasetshenziswa njengezinto zokusetshenziswa emkhakheni wezibulala-zinambuzane kanye nemithi.

Indlela:
Ukulungiswa kwe-2-chloro-3-methylpyridine ngokuvamile kwenziwa ngale ndlela elandelayo:
-Electrophilic substitution reaction of pyridine, ukwelashwa kwe-pyridine nge-chloroacetic acid kanye ne-ferrous chloride ukukhiqiza i-chloropyridine.
-Bese usabela nge-methyl alcohol ne-hydrochloric acid ukukhiqiza i-2-chloro-3-methylpyriridine.

Ulwazi Lokuphepha:
I-2-chloro-3-methylpyridine iyinhlanganisela yezinto eziphilayo. Izinyathelo ezifanele zokuphepha kufanele zithathwe lapho uphatha, njengokugqoka amagilavu ​​okuzivikela kanye nezibuko, nokugcina umoya omuhle.
-Gwema ukuthinta isikhumba namehlo. Uma kwenzeka ukuthintana, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
-Gcina kude namalangabi avulekile nemithombo yokushisa ngesikhathi sokugcina futhi usebenzise ukuvimbela amagesi ayingozi.
