Ovicic acid, oleic acid, tseem hu ua CIS-9-octadecenoic acid, ua cov tshuaj tsis txaus ntseeg ntawm cov tsiaj thiab cov roj zaub. Piv txwv li, txiv roj roj muaj txog 82.6%; txiv laum huab xeeb muaj 60.0%; noob hnav roj muaj 47.4%; Cov roj taum pauv muaj 35.5%; Sunflower noob roj muaj 34.0%; cottonseed roj muaj 33.0%; Rapoed roj muaj 23.9%; Safflower roj muaj 18.7%; Cov ntsiab lus nyob rau hauv cov roj tshuaj muaj peev xwm ua tau li siab li 83%; Hauv cov roj tsiaj: Lard roj muaj txog 51.5%; butter muaj 46.5%; Cov roj ntses ntses muaj 34.0%; Cov roj nplaum roj muaj 18.7%; Oleic acid muaj qhov ruaj khov (α-hom) thiab tsis ruaj khov (β-hom) ob hom. Ntawm qhov kub tsawg, nws tuaj yeem tshwm sim li crystal; Ntawm qhov kub thiab txias, nws zoo li tsis muaj kob kab mob oily kua nrog lard tsw. Nws muaj tus txheeb ze cov roj av loj ntawm 282.47, txheeb ze ntom ntawm 0.8905 (20 ° C (13.3 103 txog 226 ° C (1.33 103 PA), 203 txog 205 ° C (0.677 103 PA), thiab 170 rau 175 ° C (0.267 103 rau 0.400 103 teev), lub vev xaib kom tsis pom zoo ntawm 1.4582 thiab Visco • S (30 ° C).
Nws yog insoluble hauv dej, ua soluble hauv benzene thiab chloroform. Nws yog mistible nrog methanol, ethanol, ether thiab carbon tetrachloride. Vim tias muaj ob daim ntawv cog lus ob hnub, nws tuaj yeem yooj yim rau cov pa oxidation, yog li ua rau cov ntxhiab tsw phem nrog cov xim tig daj. Thaum siv nitrogen oxides, nitric acid, mercurous nitrate thiab sulfurous acid rau kev kho mob, nws tuaj yeem hloov mus rau elamic acid. Nws tuaj yeem hloov pauv mus rau hauv stearic acid thaum hydrogenation. Muab ob npaug rau nws yog ib qho yooj yim kom hnov ​​cov halogen los tsim halogen stearic acid. Nws tuaj yeem tau txais los ntawm cov roj hydrolysis ntawm cov txiv roj roj thiab lard roj, ua raws li dej distillation thiab crystallization rau kev sib cais. Ovicic acid yog cov kuab tshuaj zoo heev rau lwm cov roj, fatty acids thiab roj-solubble tshuaj. Nws tuaj yeem siv rau kev tsim cov xab npum, cov roj nplua nyeem, cov tshuaj tua ntsuag, xws li tshuaj pleev thiab tshuaj pleev thiab Oveatment.
Siv:
GB 2760-96 Txhais nws ua cov kev pab ua haujlwm. Nws tuaj yeem raug siv ua cov tshuaj tiv thaiv tiv thaiv, tshuaj tsw qab, binder, thiab roj nplua nyeem.
Nws tuaj yeem siv rau kev tsim cov xab npum, cov roj nplua nyeem, tshuaj pleev cov tshuaj pleev thiab ua kom zoo nkauj rau cov roj ntsha thiab roj-solubble tshuaj.
Nws tuaj yeem siv rau cov qauv ua kom zoo ntawm cov kub, nyiaj thiab lwm cov hlau uas muaj nqis ib yam li Polishing hauv cov kev lag luam electroplating.
Nws tuaj yeem raug siv los ua kev soj ntsuam reagents, cov kuab tshuaj, roj nplua nyeem thiab cov neeg sawv cev ntawm huab tais, tabsis kuj thov rau kev lag luam qab zib ua lag luam
Ovicic acid yog ib cov khoom siv cov tshuaj khib nyiab thiab tuaj yeem tsim Epoxidized oleic acid ester ester tom qab epoxidation. Nws tuaj yeem siv los ua yas yas thiab rau kev tsim cov Azelaic los ntawm oxidation. Nws yog cov khoom siv raw ntawm polyamide resin. Ntxiv rau, oleic acid kuj tseem tuaj yeem siv tshuaj tua kab emulsifier, muaj cov kuab tshuaj, cov ntxhia ntxas flotation tus neeg sawv cev, thiab tso tus neeg sawv cev. Ntxiv mus, nws tuaj yeem siv ua cov khoom siv raw rau chaw ua cov tshuaj carbon daim ntawv, hloov hlaws thiab ntaus ntawv siv quav ciab. Ntau yam ntawm cov khoom noj olATE yog tseem ceeb derivatives ntawm oleic acid. Raws li cov tshuaj lom neeg tshuaj lom neeg, nws tuaj yeem siv los ua cov qauv chromatographic thiab rau cov caliochemical sib piv, kuaj xyuas thiab magnesium, leej faj.
Nws tuaj yeem siv rau kev tshawb fawb biochemical. Nws tuaj yeem ua kom cov protein kinease C hauv lub siab lub siab.
Cov txiaj ntsig:
Oleic acid yog cov roj ntsha fatty acid pom nyob hauv cov tsiaj thiab zaub roj. Ovicic acid yog mono-saturated rog feem ntau ntseeg kom ua tau zoo rau ib qho kev noj qab haus huv. Qhov tseeb, nws yog tus thawj fatty acid pom nyob rau hauv cov txiv ntseej roj, suav nrog 55 rau 85 feem pua ​​ntawm cov yam ntxwv ntawm kev kho mob vim nws cov khoom siv qub. Cov kev tshawb fawb niaj hnub txhawb cov kev xav ntawm cov nyiaj ntawm cov roj av, vim tias muaj cov ntshav ntws tsawg Pom hauv cov khoom tseem ceeb hauv canola, cod lub siab, ib qho uas yuav tau noj ntau yam ntawm cov roj ntsha muaj txiaj ntsig ntau dua los ntawm kev siv zog ntawm genetic engineers.
Ovicic acid tshwm sim nyob rau hauv cov ntau dua nyob rau hauv ntau dua lwm cov rog acid. Nws yog tam sim no ua glycerides hauv feem ntau cov rog thiab roj. Cov siab muaj cov oleic acid tuaj yeem txo cov ntshav roj qis dua cov roj (cholesterol. Nws yog siv nyob rau hauv kev lag luam khoom noj kom ua hluavtaws tab sis chees. Nws tseem siv rau cov khoom ci ci muag, khaub noom, mis nyuj khov, thiab dej qab zib.
Raws li cov koomhaum Asmeskas cov ntshav qab zib, ntau dua 25 lab Asmeskas muaj ntshav qab zib. Ib qho ntxiv, 7 lab muaj ntshav qab zib ntshav qab zib ntshav qab zib ntshav qab zib, thiab 79 lab lwm tus muaj kev ua neej. Hauv kev kawm ntawv luam tawm thaum lub Ob Hlis 2000 hauv lub tsev kho mob kev nplua nuj nyob rau hauv oleic acid tau zoo rau cov neeg koom nrog 'relfin acid zoo li, insulin rhiab thiab cov ntshav ncig. Kev nrawm nrawm flucose thiab cov tshuaj insulin ntau ntau, nrog rau cov ntshav qab zib txhim kho, qhia cov ntshav qab zib zoo dua thiab tsis muaj kev pheej hmoo zoo dua rau lwm yam kab mob. Rau lab tus tib neeg nrog kuaj cov ntshav qab zib thiab prediagetes, siv cov zaub mov nplua nuj nyob rau oleic acid yuav tau txais txiaj ntsig hauv kev tswj tus kabmob.
