- Kub taw tes: 169-171 ° C.
- Qhov ceev: txog 1.158g / cm³.
-Solubility: Soluble nyob rau hauv anhydrous ether, chloroform, benzene thiab ethanol.Siv:
-2-chloroo-3-methylpyridine tuaj yeem siv los ua ib qho tseem ceeb nruab nrab ntawm cov organic synthesis thiab siv rau hauv kev sib txuas ntawm lwm cov organic sib txuas.
-Nws tuaj yeem siv los ua cov khoom siv raw hauv cov tshuaj tua kab thiab tshuaj.
Txoj kev:
Kev npaj ntawm 2-chloro-3-methylpyridine feem ntau yog ua los ntawm cov qauv hauv qab no:
-Electrophilic hloov cov tshuaj tiv thaiv pyridine, kho pyridine nrog chloroacetic acid thiab ferrous chloride los tsim chloropyridine.
-Tom qab ntawd hnov mob nrog methyl cawv thiab hydrochloric acid los tsim 2-chloro-3-methylpyriridine.
Cov ntaub ntawv kev nyab xeeb:
- 2-chloro-3-methylpyridine yog cov organic compound. Kev ntsuas kev nyab xeeb tsim nyog yuav tsum tau ua thaum tuav, xws li hnav cov hnab looj tes tiv thaiv thiab tsom iav, thiab tswj qhov cua kom zoo.
-Tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Yog tias muaj kev sib cuag, yaug tam sim nrog dej ntau thiab nrhiav kev pab kho mob.
- Khaws kom deb ntawm cov nplaim taws thiab qhov chaw sov thaum lub sijhawm khaws cia thiab siv los tiv thaiv cov pa phem.
