Indlela yokukhiqiza

Chaza i-L-cysteine ​​hydrochloride (ngaphandle kwamanzi ayikristalu) emanzini acwecwe izikhathi ezingu-0.8, bese uwashisa ngendlela efanele. Bese uyihluza kufaneli enekhabhoni ecushiwe. Engeza izikhathi ezingu-3.6 zevolumu ye-ethanol yokwelapha engu-95% ku-filtrate, bese wengeza i-pyridine yezimboni (izikhathi ezingu-0.8 zevolumu yencwadi yamakhemikhali).

Okokuqala uyipholise emanzini okugeza e-ice, bese uyifaka esiqandisini ubusuku bonke. Ngosuku olulandelayo, lihlunge, ligeze nge-chloroform (umkhiqizo wezimboni), lihlunge, licindezele, licindezele, lifake ngokushesha endaweni yokomisa i-vacuum, bese liyomisa ekamelweni lokushisa amahora angu-5 ukuze uthole i-L-cysteine. Isivuno saba ngu-86.5%.
