2-Chloro-3-picoline (CAS# 18368-76-8) Chiyambi
-Maonekedwe: Madzi opanda mtundu kapena opepuka achikasu.
-mamolekyu achibale: 129.57.
- Malo osungunuka: -30 ° C.
-Kuwira: 169-171 ° C.
- Kachulukidwe: pafupifupi 1.158g/cm³.
-Kusungunuka: Kusungunuka mu anhydrous ether, chloroform, benzene ndi ethanol.
-2-chloroo-3-methylpyridine angagwiritsidwe ntchito ngati yofunika wapakatikati mu kaphatikizidwe organic ndi ntchito synthesis ena organic mankhwala.
-Itha kugwiritsidwa ntchito ngati zida zopangira mankhwala ophera tizilombo komanso mankhwala.
Njira:
Kukonzekera kwa 2-chloro-3-methylpyridine nthawi zambiri kumachitika motere:
- Electrophilic m'malo mmene pyridine, mankhwala pyridine ndi chloroacetic acid ndi ferrous kolorayidi kupanga chloropyridine.
-Kenako muzichita ndi methyl mowa ndi hydrochloric acid kuti mupange 2-chloro-3-methylpyriridine.
Zambiri Zachitetezo:
- 2-chloro-3-methylpyridine ndi organic pawiri. Njira zodzitetezera ziyenera kuchitidwa pogwira, monga kuvala magolovesi oteteza ndi magalasi, ndi kusunga mpweya wabwino.
-Pewani kukhudza khungu ndi maso. Ngati kukhudzana kwachitika, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.
- Khalani kutali ndi malawi otseguka ndi magwero otentha panthawi yosungira ndikugwiritsa ntchito kupewa mpweya woipa.
