Mawu Oyamba
S-(-) -2-chloropropionic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zopangira ndi chitetezo:
Katundu: S-(-)-2-chloropropionic acid ndi madzi opanda mtundu komanso onunkhira. Imasungunuka m'madzi ndi ethanol ndipo imasungunuka mu ether. Kutentha kwa chipinda, imakhala ndi mphamvu ya mpweya wochepa.
Ntchito: S-(-) -2-chloropropionic acid amagwiritsidwa ntchito ngati reagent, chothandizira komanso chapakatikati mu kaphatikizidwe ka organic.
Njira yokonzekera: Pali njira ziwiri zazikulu zokonzekera za S-(-) -2-chloropropionic acid. Njira imodzi ndi kupeza mchere wa sodium wa S-(-) -2-chloropropionate ndi zochita za phenylsulfonyl chloride ndi sodium ethanol albutan, ndiyeno acidify kupanga chandamale mankhwala. Njira ina ndi yothira chlorine ndi hexanone ndi hydrogen chloride pamaso pa okosijeni, kutsatiridwa ndi acidification kuti mupeze chinthu chomwe mukufuna.
Chidziwitso chachitetezo: S-(-)-2-chloropropionic acid imakwiyitsa ndipo iyenera kupewedwa pokhudzana ndi khungu ndi maso. Zida zodzitetezera zoyenera, monga magolovesi ndi magalasi, ziyenera kuvala pogwira ntchito. Sungani pamalo opanda mpweya, kutali ndi moto ndi ma oxygen.
