CALB aan dhaqdhaqaaq lahayn
CALB waxa ay maamushaa xayeysinta jirka ee xabagta hydrophobic ee aadka u sarreeya kaas oo ah polymer-ka-makroporous, styrene/methacrylate.CALB ee aan dhaqaaqin waxay ku habboon tahay codsiyada dareerayaasha organic iyo nidaamyada aan dareeraha lahayn, waxaana dib loo warshadayn karaa oo dib loo isticmaali karaa marar badan xaaladaha ku habboon.
Xeerka Alaabta: SZ-CALB- IMMO100A, SZ-CALB- IMMO100B.
★ Dhaqdhaqaaq sare, xulashada chiral sare iyo xasilloonida sare.
★Waxqabadka wanaagsan ee wejiyada aan biyaha lahayn.
★Si sahal ah uga saar nidaamka falcelinta, si degdeg ah u jooji falcelinta, kana fogow hadhaaga borotiinka ee alaabta.
★Waa dib loo warshadayn karaa oo dib loo isticmaali karaa si loo dhimo kharashka.

Qeexitaan halbeeg: 1 unug waxay u dhigantaa isku dhafka 1μmol daqiiqaddii propyl laurate ee lauric acid iyo 1-propanol at 60℃.CALB-IMMP100-A ee kore iyo CALB-IMMO100-B waxay u dhigmaan sidayaal aan dhaqdhaqaaq lahayn oo leh cabbirro kala duwan.
1. Nooca reactor
Insaymiska aan dhaqdhaqaaqa lahayn ayaa lagu dabaqi karaa reactor-ka dufcada kettle iyo reactor-ka sariirta go'an ee joogtada ah.Waa in la ogaadaa in la iska ilaaliyo burburinta sababtoo ah xoogga dibadda inta lagu jiro quudinta ama buuxinta.
2. falcelinta pH, heerkulka iyo dareeraha
Insaymiska aan dhaqdhaqaaqa lahayn waa in lagu daraa ugu dambeeya, ka dib marka walxaha kale lagu daro oo la milmo, pH la hagaajiyo.
Haddii isticmaalka substrate-ka ama samaynta alaabtu ay u horseedi doonto isbeddelka pH inta lagu jiro falcelinta, bakhaar ku filan waa in lagu daraa habka falcelinta, ama pH waa in lala socdo oo la hagaajiyaa inta lagu jiro falcelinta.
Dhexdhexaadinta dulqaadka heerkulka CALB (ka hooseeya 60 ℃), heerka beddelka ayaa kordhay kororka heerkulka.Isticmaalka dhabta ah, heerkulka falcelinta waa in lagu doortaa iyadoo loo eegayo xasilloonida substrate ama alaabta.
Guud ahaan, falcelinta ester hydrolysis waxay ku habboon tahay nidaamka wajiga biyaha, halka falcelinta ester-ku ay ku habboon tahay nidaamka wajiga dabiiciga ah.Walxaha dabiiciga ah wuxuu noqon karaa ethanol, tetrahydrofuran, n-hexane, n-heptane iyo toluene, ama dareere isku dhafan oo ku habboon.Dareen-celinta qaar ka mid ah dareerayaasha organic, 3% biyaha ayaa lagu dari karaa si loo hagaajiyo saameynta falcelinta.
3. Dib u isticmaalka iyo nolosha adeegga CALB
Marka la eego xaaladda falcelinta ku habboon, CALB waa la soo kaban karaa oo dib loo isticmaali karaa, iyo waqtiyada codsiga gaarka ah waxay ku kala duwan yihiin mashaariic kala duwan.
Haddii CALB-ka la soo kabsaday aan dib loo isticmaalin si joogto ah oo u baahan yahay in la kaydiyo ka dib soo kabashada, waxay u baahan tahay in la dhaqo oo la qalajiyo oo lagu xidho 2-8 ℃.
Dhawr wareeg oo dib loo isticmaalo ka dib, haddii waxtarka falcelinta wax yar la dhimo, CALB si habboon ayaa loogu dari karaa oo waa la sii wadi karaa isticmaalka.Haddii waxtarka falcelinta si dhab ah loo yareeyo, waxay u baahan tahay in la beddelo.
