4 6-dichloropyridine-3-carbonitrile (CAS# 166526-03-0) Isingeniso
-Ukubukeka: 4, kuwuketshezi olungenambala oluphuzi olukhanyayo.
-I-Solubility: Ine-solubility enhle kuma-solvents ajwayelekile.
-Iphuzu lokuncibilika nendawo yokubilisa: indawo yokuncibilika ngu -10 ℃, indawo yokubila ngu-230-231 ℃.
-Ukuminyana: Ukuminyana ngu-1.44g/cm³(20°C).
-Ukuzinza: Kuzinzile, kodwa gwema ukuthintana nama-oxidants aqinile.
Sebenzisa:
- 4, ivame ukusetshenziswa njenge-reagent futhi iphakathi ku-organic synthesis.
-Ingasetshenziswa ukwenza izidakamizwa ezifana ne-carbamazepine.
-ingasetshenziswa futhi ukuhlanganisa izinhlobo ezihlukahlukene zezibulala-zinambuzane nodayi.
Indlela:
- 4, ukulungiswa kuvame ukutholwa ukusabela kwe-chlorination ngokwengxenye ye-pyridine.
-Indlela ethize yokulungiselela kungaba ukusabela i-pyridine nge-benzyl chloride ngaphansi kwe-acid catalysis, bese i-hydrolyze nge-concentrated aqueous hydrochloric acid ukuthola i-4.
Ulwazi Lokuphepha:
- 4, iyinhlanganisela yezinto eziphilayo. Gwema ukuhogela, ukumunca noma ukuthinta isikhumba.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu elebhu, izibuko nezingubo zokuzivikela lapho usebenzisa.
-Uma kwenzeka uthinta isikhumba noma amehlo ngengozi, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
-Landela izinqubo zokuphepha ezifanele ngesikhathi sokugcina nokuphatha, futhi ugweme isitoreji esinemithombo yokuthungela noma ama-oxidants aqinile.
