Txoj kev tsim khoom

Dissolve L-cysteine ​​hydrochloride (tsis muaj dej siv lead ua) hauv 0.8 npaug ntawm cov dej distilled, thiab tom qab ntawd rhaub kom tsim nyog. Tom qab ntawd lim nws nyob rau hauv ib lub funnel nrog activated carbon. Ntxiv 3.6 npaug ntawm qhov ntim ntawm 95% tshuaj ethanol rau cov lim dej, thiab tom qab ntawd ntxiv cov pyridine (0.8 npaug ntawm cov ntaub ntawv tshuaj).

Ua ntej txias nws hauv ib da dej dej khov, thiab tom qab ntawd muab tso rau hauv lub tub yees thaum hmo ntuj. Hnub tom qab, lim nws, ntxuav nws nrog chloroform (cov khoom lag luam), lim nws, nias kom qhuav, sai sai muab tso rau hauv lub tshuab nqus tsev, thiab ziab hauv chav sov li 5h ​​kom tau L-cysteine. Cov txiaj ntsig yog 86.5%.
