EOS, ib lub tuam txhab German, tau ua lag luam rau kev tsim cov dav hlau cav hniav, txuas nws lub neej kev pab cuam los ntawm 50%.
Los ntawm kev tshawb fawb yooj yim hauv kev tshawb fawb txog lub neej mus rau kev txiav- kev tshawb nrhiav ntug hauv kev tsim khoom lag luam, L- cysteine, nrog rau nws cov khoom siv tshuaj lom neeg thiab cov khoom siv roj ntsha, tseem ua rau muaj kev txhim kho tshiab hauv kev lag luam xws li tshuaj, zaub mov, tshuaj pleev ib ce, thiab kev ua liaj ua teb. Nyob rau hauv lub neej yav tom ntej, nrog kev ua tiav hauv kev sib koom ua ke xws li hluavtaws biology thiab nanotechnology, daim ntawv thov ciam teb ntawm L-cysteine yuav nthuav dav ntxiv, muab kev txhawb nqa tseem ceeb rau tib neeg kev noj qab haus huv thiab kev txhim kho kom ruaj khov. Txawm li cas los xij, nrhiav kev sib npaug ntawm kev ua tau zoo thiab kev nyab xeeb (xws li kev tswj cov hlau hnyav thiab ua kom cov txheej txheem ntau lawm) tseem yog ib qho tseem ceeb hauv cov txheej txheem kev lag luam ntawm L-cysteine.
Muaj peb txoj hauv kev tseem ceeb ntawm kev sib xyawL-cystine hmoov:
① Cov kua dej alkaline ntawm L-cysteine yog oxidized los ntawm huab cua.
② Nws tuaj yeem muab rho tawm los ntawm cov plaub hau, tshwj xeeb tshaj yog cov plaub hau nees, nrog rau cov ntsiab lus ntawm 8%. Cov plaub hau yog hydrolyzed nyob rau hauv acid ntawm 110℃los yog keratin yog hydrolyzed. Tom qab tshem tawm impurities, neutralize nrog alkali rau pH =4.8, thiab crystallize kom tau cov khoom nyoos. Tom qab ntawd, ua kom sov rau lawv kom yaj hauv hydrochloric acid, ntxiv cov pa roj carbon activated rau decolorize, lim, neutralize nrog ammonia, recrystallize, thiab ntxuav cov lim kom txog thaum nws tsis muaj chloride thiab hlau ions.
③ Los ntawm cov khoom ntawm tyrosine ntau lawm:
Hauv kev lag luam, nws tsuas yog muab rho tawm los ntawm cov plaub hau nrog cov txiaj ntsig ntawm 7.5-8%. Qee tus ntawm lawv tsuas yog ncav cuag 5% hauv kev tsim khoom tiag tiag.
Tshwj xeeb:
Ntxiv 720kg hydrochloric acid nrog ib qho concentration ntawm 10mol / L rau hauv lub tank hydrolysis, cua sov rau 70 ~ 80 degree, sai sai muab 400kg tib neeg cov plaub hau los yog npua rau hauv lub tank, txuas ntxiv kom sov nws mus rau 100 degree, thiab kub nws mus txog 110 ~ 117℃nyob rau hauv 1 ~ 1.5h, hydrolyze nws rau 10 ~ 6. nws . 30% ~ 40% muaj sodium hydroxide tov yog ntxiv rau lub filtrate nyob rau hauv stirring.
Thaum tus nqi ph nce mus txog 3.0, cov tshuaj alkali ntxiv ntawm qhov txo qis kom txog thaum tus nqi ph yog 4.8.
Tom qab sawv ntsug rau 36 teev, cov nag lossis daus yog sib cais thiab centrifuged kom qhuav kom tau cov cystine crude (I).
Niam cawv muaj glutamic acid, arginine, leucine, thiab lwm yam.
Qhov hnyav 150kg ntawm crude cystine (I), ntxiv txog 90kg ntawm 10mol / L hydrochloric acid thiab 360kg dej, sov lawv mus rau 65 ~ 70 degree, do thiab dissolve lawv rau 0.5h, ces ntxiv 12kg ntawm activated carbon, sov rau 80 ~ 90 degree, cia lawv sov so rau phaj thiab lim rau 0.5h.
Tshav kub lub filtrate rau 80 ~ 85 degree, ntxiv 30% sodium hydroxide thaum nplawm, thiab nres ntawm ph 4.8. Cia nws sawv ntsug, ua kom cov crystal precipitate, siphon lub supernatant, cais lub hauv qab precipitate, thiab ces centrifuge thiab qhuav nws kom tau crude cystine (II).
Nyhav 100kg ntawm crude cystine (II), ntxiv 500L ntawm 1mol / L hydrochloric acid, kub rau 70 degree, thiab ces ntxiv 3-5 kg ntawm active carbon.
Tom qab ntawd, qhov kub thiab txias yuav tsum tau nce mus rau 85 degree, kev txuag hluav taws xob thiab nplawm yuav tsum tau ua rau 0.5h, thiab lub phaj thiab thav duab lim yuav tsum nias.
Ntxiv 1.5 npaug ntawm cov dej distilled rau hauv cov dej lim, kub rau 75 ~ 80 degree, neutralize nrog 12% ammonia nyob rau hauv stirring rau ph3.5-4.0, thiab cystine yuav crystallize.
Lub tiav lawm L-cystine hmoov tuaj yeem tau los ntawm crystallization centrifugation thiab ziab, ntxuav nrog dej distilled kom txog thaum tsis muaj chloride ion, thiab nqus kom qhuav. Cov txiaj ntsig ntawm tib neeg cov plaub hau tuaj yeem ncav cuag 8%, thiab cov txiaj ntsig ntawm cov plaub hau npua tuaj yeem ncav cuag 5%.
