Hordhac
3-Chloro-4-methylpyridine waa unug dabiici ah. Astaanteedu waa sida soo socota:
1. Muuqashada:3-chloro-4-methylpyridinewaa dareere huruud ah oo aan midab lahayn ama iftiin leh.
2. Cufnaanta: 1.119 g/cm³
4. Solubility: 3-chloro-4-methylpyridine waxay ku milmi kartaa inta badan dareerayaasha dabiiciga ah oo aan lagu milmin biyaha.
Isticmaalka ugu muhiimsan ee 3-chloro-4-methylpyridine waa sida soo socota:
1. Synthesis of complexs biraha kala-guurka: Waa dhexdhexaadiye muhiim ah oo loo isticmaalo isku-duwidda kimistariga ee isku-dhafka alkolada amino, amino alkates, iyo xeryahooda kale ee nitrogen heterocyclic.
2. Dhexdhexaadiyeyaasha sunta cayayaanka: 3-chloro-4-methylpyridine waxaa loo isticmaali karaa dhexdhexaad ah qaar ka mid ah cayayaanka iyo herbicides.
Habka diyaarinta 3-chloro-4-methylpyridine caadi ahaan waxaa ka mid ah tallaabooyinka soo socda:
1. Falcelinta Nitroation of pyridine: pyridine waxaa lagu falceliyaa nitric acid iyo sulfuric acid si loo helo 3-nitropyridine.
2. Dareen-celinta dhimista: 3-nitropyridine waxaa lagu falceliyaa xad-dhaaf ah sulfoxide iyo yaraynta wakiilka (sida budada zinc) si loo helo 3-aminopyridine.
3. Dareen-celinta chlorination: 3-aminopyridine waxaa lagu falceliyaa thionyl chloride si loo helo 3-chloro-4-methylpyridine.
Macluumaadka badbaadada khuseeya ee 3-chloro-4-methylpyridine waa sida soo socota:
1. Dareenka: Waxaa laga yaabaa inay dareen-celin xasaasiyadeed ku yeelato dadyow gaar ah.
2. Cuncun: Waxa laga yaabaa in ay saamayn cuncun leh ku yeelato indhaha, hab-dhiska neefsiga iyo maqaarka.
3. Sumoobid: Waxay sun u tahay caafimaadka bini'aadamka waana in ay raacaan habraacyada qalliinka ee badbaadada habboon.
4. Kaydinta: waa in lagu kaydiyaa weel aan hawadu karin, kana fog dabka iyo oxidants, kana fog taabashada hawada.
Markaad isticmaalayso 3-chloro-4-methylpyridine, raac nidaamka badbaadada ee khuseeya sida xidhashada muraayadaha indhaha, galoofyada iyo dharka ilaalinta, oo hubi in lagu shaqeeyo meel hawo fiican leh. Haddii ay dhacdo xiriir shil ah ama neefsashada, raadso daryeel caafimaad isla markiiba oo tus xaashida xogta badbaadada alaabta dhakhtarkaaga.
