Taw qhia

S-(-)-2-chloropropionic acid yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Cov Khoom Siv: S-(-)-2-chloropropionic acid yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws yog soluble hauv dej thiab ethanol thiab insoluble hauv ether. Nyob rau hauv chav tsev kub, nws muaj ib tug nruab nrab vapor siab.

 

Kev Siv: S-(-)-2-chloropropionic acid feem ntau yog siv los ua reagent, catalyst thiab nruab nrab hauv cov organic synthesis.

 

Txoj kev npaj: Muaj ob txoj kev npaj tseem ceeb ntawm S-(-)-2-chloropropionic acid. Ib txoj hauv kev yog kom tau txais sodium ntsev ntawm S-(-)-2-chloropropionate los ntawm cov tshuaj tiv thaiv ntawm phenylsulfonyl chloride thiab sodium ethanol albutan, thiab tom qab ntawd acidify nws los tsim cov khoom lag luam. Lwm txoj kev yog chlorinate los ntawm hexanone thiab hydrogen chloride nyob rau hauv lub xub ntiag ntawm oxidant, ua raws li los ntawm acidification kom tau lub hom phiaj cov khoom.

 

Cov ntaub ntawv kev nyab xeeb: S-(-)-2-chloropropionic acid yog khaus khaus thiab yuav tsum tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag. Cov cuab yeej tiv thaiv tsim nyog, xws li hnab looj tes thiab tsom iav, yuav tsum hnav thaum ua haujlwm. Khaws rau hauv qhov chaw airtight, kom deb ntawm hluav taws thiab oxidants.
