20712-16-7 - Lus Qhia

Nws yog ib qho organic compound nrog cov tshuaj formula C7H8ClN. Cov hauv qab no yog cov lus piav qhia ntawm nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv: Xwm:
-Zoo: Nws yog dawb crystalline khoom.
-Solubility: Nws solubility hauv dej tsawg, tab sis nws tuaj yeem yaj hauv cov kuab tshuaj organic (xws li ethanol thiab dimethylformamide).
-Stability: Nws yog qhov ruaj khov ntawm chav tsev kub thiab tuaj yeem decomposed nyob rau hauv lub teeb los yog cua sov tej yam kev mob.Siv:
Nws muaj ntau yam kev siv hauv thaj tsam ntawm cov organic synthesis.
-Nws tuaj yeem siv los ua qhov nruab nrab rau kev sib txuas ntawm pyridine tebchaw thiab lwm cov organic tebchaw.
-Nyob rau hauv tshuaj synthesis, nws yog feem ntau yog siv los ua ib tug hluavtaws raw khoom rau Antibacterial Drugs thiab antiparasitic tshuaj.

Txoj kev:
Nws tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv hauv qab no:
- Ua ntej, 3-picoline reacts nrog sodium chloride nyob rau hauv lub xub ntiag ntawm sodium carbonate los tsim 2-methyl-3-chloropyridine.
-Tom qab ntawd, 2-methyl -3-chloropyridine reacts nrog ammonia nyob rau hauv carbonate buffer tov los tsim ib pyridine.

Cov ntaub ntawv kev nyab xeeb:
-Rau kev siv thiab kev ua haujlwm ntawm cov tshuaj, thov xa mus rau Daim Ntawv Qhia Kev Nyab Xeeb (MSDS) thiab cov kev ua haujlwm tsim nyog.
-Tej zaum yuav ua rau tawv nqaij, qhov muag thiab ua pa.
-Thaum siv, tsis txhob nqus cov aerosols lossis tiv nrog daim tawv nqaij thiab qhov muag.
-Hauv kev ua haujlwm, yuav tsum ua raws li kev ntsuas kev nyab xeeb tsim nyog, xws li hnav hnab looj tes tiv thaiv, tsom iav kev nyab xeeb thiab lub ntsej muag tiv thaiv.
