Taw qhia
2-Chloro-6-methyl-5-nitropyridine yog ib hom organic compound,
Zoo:
- Cov tsos mob: 2-chloro-6-methyl-5-nitropyridine yog xim tsis muaj xim lossis daj crystalline khoom.
- Solubility: Nws yooj yim soluble hauv cov kuab tshuaj organic xws li ethanol, dimethylformamide thiab chloroform.
Siv:
- Dyes: Cov tshuaj no tuaj yeem siv los ua ke qee qhov kev lag luam dyes, xws li cov qauv muaj cov cuab yeej nqus UV teeb, thiab siv dav hauv kev lag luam pigment thiab dyeing.
Txoj kev:
2-Chloro-6-methyl-5-nitropyridine tuaj yeem tau txais los ntawm chlorination thiab nitrification ntawm pyridine. Txoj kev npaj tshwj xeeb tuaj yeem siv nitric acid thiab sulfuric acid los ua kom tau nitrite acid, react nitrite thiab tooj liab nitrate los tsim tooj liab nitrate, thiab tom qab ntawd siv electrophilic methylation reagents (xws li methyl halogen) los teb nrog tooj liab nitrate kom tau txais phiaj khoom.
Cov ntaub ntawv kev nyab xeeb:
2-Chloro-6-methyl-5-nitropyridine yog ib qho tshuaj lom uas ua rau khaus thiab txaus ntshai. Thaum siv thiab tuav, yuav tsum tau ceev faj kom tsim nyog xws li hnav looj tsom iav, hnab looj tes thiab khaub ncaws tiv thaiv. Tsis txhob nqus nws cov vapors lossis hmoov av, thiab tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Thaum siv cov tshuaj no, kev saib xyuas yuav tsum tau ua kom nws ruaj khov thiab tsis txhob sib cuag nrog lwm cov tshuaj tsis sib xws. Thaum khaws cia, nws yuav tsum tau muab cia rau hauv lub thawv airtight, kom deb ntawm ignition thiab oxidants.
