Txoj kev ua kom muaj peev xwm txhim kho kev rho tawm cov roj thiab cov ntsiab lus yuav tsum tau them rau kev xaiv kev nyab xeeb thiab kev ua phooj ywg ib puag ncig.
Supercritical CO2 cov txheej txheem kua dej rho tawm
Supercritical Co2 cov kua dej rho tawm yog hom tshiab ntawm cov roj extraction thev naus laus zis. Nyob rau hauv supercritical lub xeev, qhov ntom thiab solubility ntawm CO2 kua yog nyob ze rau cov ntawm cov kua, thiab nws tuaj yeem xaiv cov ntaub qhwv linoleic acid los ntawm roj. Cov kauj ruam tshwj xeeb suav nrog:
Npaj SuperCritical CO2 FLL:
Particurize CO2 rau lub xeev supercritical (feem ntau nrog lub siab dua li 7.38 MPa thiab qhov kub thiab txias dua 31.1 Qib).

04
Supercritical CO2 cov txheej txheem cov kua dej muaj zog muaj qhov zoo, kev tiv thaiv ib puag ncig, thiab cov cuab yeej siv tau siab yog qhov xwm txheej siab thiab kev ua haujlwm hnyav.
Synthesis txoj kev
Txawm hais tias cov roj muab rho tawm los ntawm cov roj pob kws muaj cov ntaub qhwv ua kab, nws cov ntsiab lus thiab kev ua yeeb yam feem ntau tsis tuaj yeem ua raws li cov cai. Yog li ntawd, nws yog ib qho tsim nyog los txuas ntxiv nrog cov hluavtaws siab ntxiv - purity linoleic acid los ntawm kev siv tshuaj lom lossis kev lom zem. Cov hauv qab no yog ib qho piv txwv ntawm cov hluavtaws raws cov qauv:
Sib tov cov roj ua kom huv nrog cov alkali (xws li sodium hydroxide) kev daws teeb meem thiab ua cov kev coj ua ntawm cov tshuaj tiv thaiv cov cua sov raws li cov cua kub. Cov tshuaj tiv thaiv saponification yog ib qho tshuaj tiv thaiv nyob rau hauv uas cov rog thiab roj yog nyob rau hauv Alkaline tej yam kev mob los tsim cov roj fatty acid ntsev thiab glycerol. Qhov kev tshwm sim tshwj xeeb yog raws li hauv qab no:
R1r2ch {= chr3r4cooh+ 3 →} {{9} chr3r4coona + glycerol
Ntawm lawv, $ R1, R2, R3, R4 $ sawv cev cov pawg sib txawv sib txawv.
Acidty acid ntsev tau txais los ntawm saponification cov tshuaj tiv thaiv nrog kua qaub (xws li sulfuric acid) kom hloov lawv rov qab mus rau hauv fatty acids. Qhov kev tshwm sim tshwj xeeb yog raws li hauv qab no:
R1r2ch {= chr3r4coona + h2so4 → r1r2ch {{} chr3r4cooh + na2coo4
Ntawm lawv, R1R2R3R3r4 sawv cev rau cov pab pawg hydrocarbon ntsig txog linoleic acid. Nws yuav tsum raug sau tseg tias kev sib npaug ntawm no yog qhov yooj yim, thiab qhov tseeb, cov khoom muaj roj, yog li cov tshuaj tiv thaiv cov roj ntsha. Txawm li cas los xij, vim yog cov ntsiab lus tseem ceeb ntawm cov roj pob kws ua pob kws, nws tuaj yeem raug cais ntxiv thiab ua kom dawb huv los ntawm cov kauj ruam tom ntej.
Kev sib cais thiab kev ua kom huv yog cov kauj ruam tseem ceeb hauv kev rho tawm siab siab {{}} purity linoleic acid. Cov hau kev sib xws suav nrog cov kuab tshuaj extraction, distillation, crystallization, thiab lwm yam.
Cov kuab tshuaj extraction:
Kev rho tawm los ntawm kev siv qhov sib txawv hauv solubility ntawm linoleic acid hauv cov kuab tshuaj sib txawv. Piv txwv li, ib qho kev daws teeb meem nrog cov solubility siab rau linoleic acid thiab qis solubility rau lwm cov neeg siv hluav taws xob tuaj yeem tau txais los ntawm kev thuam cov kuab tshuaj.
Distillation:
Siv qhov sib txawv hauv kev kub ntawm linoleic acid thiab lwm yam fatty acids rau distillation sib cais. Los ntawm kev tswj lub distillation kub thiab siab, linoleic acid tuaj yeem sib cais los ntawm cov sib tov. Txawm li cas los xij, vim yooj yim oxidation thiab decomposition yooj yim ntawm linoleic acid ntawm qhov kub, tus txheej txheem distillation yuav tsum tau tswj ntawm cov xwm txheej.
Crystallization:
Dissolve crude linoleic acid in an appropriate solvent, and then obtain high-purity linoleic acid crystals by cooling crystallization. Thaum lub sij hawm crystallization txheej txheem, linoleic acid lwg me me yuav npaj ua ib qho qauv los ua tus qauv siv lead ua los ua qauv crystal, yog li sib cais los ntawm lwm cov impurities.
Lub huvLinoleic acid kuaYuav tsum tau yauv mus ua ntu zus ntawm kev ntsuas tshuaj ntsuam xyuas kom paub tseeb tias nws muaj kev coj dawb huv thiab kev ua tau zoo. Cov hau kev tshawb xyuas xws li cov roj chromatography (GC), kua chromatography (ms), thiab lwm yam, thiab ua tau imcole acid.
