Oleic acid, Oleic acid, tseem hu ua cis-9-octadecenoic acid, yog cov tshuaj muaj zog ntawm ib qho tsis muaj carboxylic acid thiab tau nthuav dav hauv tsiaj thiab zaub roj.Piv txwv li, cov roj txiv roj muaj txog 82.6%;txiv laum huab xeeb muaj 60.0%;sesame roj muaj 47.4%;soybean roj muaj 35.5%;sunflower noob roj muaj 34.0%;cottonseed roj muaj 33.0%;rapeseed roj muaj 23.9%;safflower roj muaj 18.7%;cov ntsiab lus hauv cov tshuaj yej roj tuaj yeem siab txog 83%;nyob rau hauv tsiaj roj: lard roj muaj li ntawm 51.5%;butter muaj 46.5%;whale roj muaj 34.0%;cream roj muaj 18.7%;Oleic acid muaj qhov ruaj khov (α-type) thiab tsis ruaj khov (β-type) ob hom.Thaum tsis tshua muaj kub, nws tuaj yeem tshwm sim li siv lead ua;ntawm qhov kub thiab txias, nws zoo li tsis muaj xim pob tshab oily kua nrog lard tsw.Nws muaj cov txheeb ze molecular loj ntawm 282.47, txheeb ze ntom ntawm 0.8905 (20 ℃ kua), Mp ntawm 16.3 ° C (α), 13.4 ° C (β), boiling point ntawm 286 ° C (13.3 103 Pa), 225 txog 226 °C (1.33 103 Pa), 203 txog 205 ° C (0.677 103 Pa), thiab 170 txog 175 ° C (0.267 103 rau 0.400 103 Pa), qhov ntsuas qhov ntsuas ntawm 1.4582 thiab viscosity ntawm 25 ° C (Pas 3 m) ).
Nws yog insoluble hauv dej, soluble hauv benzene thiab chloroform.Nws yog miscible nrog methanol, ethanol, ether thiab carbon tetrachloride.Vim tias muaj ob daim ntawv cog lus, nws tuaj yeem yooj yim raug rau huab cua oxidation, yog li ua tsis hnov ​​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 elaidic acid.Nws tuaj yeem hloov mus rau hauv stearic acid thaum hydrogenation.Ob daim ntawv cog lus yog ib qho yooj yim rau cov tshuaj halogen los tsim halogen stearic acid.Nws tuaj yeem tau txais los ntawm hydrolysis ntawm cov roj txiv roj thiab roj lard, tom qab ntawd los ntawm chav distillation thiab crystallization lossis rho tawm rau kev sib cais.Oleic acid yog ib qho hnyav hnyav rau lwm cov roj, fatty acids thiab roj-soluble tshuaj.Nws tuaj yeem siv rau kev tsim cov xab npum, lubricants, flotation agents, xws li tshuaj pleev thiab oleate.
Kev siv:
GB 2760-96 txhais tias nws yog kev pab ua haujlwm.Nws tuaj yeem siv los ua tus neeg sawv cev antifoaming, tshuaj tsw qab, binder, thiab lubricant.
Nws tuaj yeem siv rau kev tsim cov xab npum, lubricants, flotation agents, ointment thiab oleate, kuj yog ib qho hnyav hnyav rau fatty acids thiab roj-soluble tshuaj.
Nws tuaj yeem siv rau kev polishing zoo ntawm kub, nyiaj thiab lwm yam hlau zoo li polishing hauv kev lag luam electroplating.
Nws tuaj yeem siv los ua cov tshuaj ntsuam xyuas, cov kuab tshuaj, cov roj nplua nyeem thiab cov neeg sawv cev flotation, tab sis kuj siv rau kev lag luam qab zib.
Oleic acid yog cov organic chemical raw khoom thiab tuaj yeem tsim epoxidized oleic acid ester tom qab epoxidation.Nws tuaj yeem siv los ua cov yas yas thiab rau kev tsim cov azelaic acid los ntawm oxidation.Nws yog cov khoom siv raw ntawm polyamide cob.Tsis tas li ntawd, oleic acid kuj tseem siv tau los ua tshuaj tua kab emulsifier, luam ntawv thiab dyeing auxiliaries, industrial solvents, hlau ntxhia flotation tus neeg sawv cev, thiab tso tawm tus neeg sawv cev.Ntxiv mus, nws tuaj yeem siv los ua cov khoom siv raw rau kev tsim cov ntawv carbon, round hlaws thiab typing wax paper.Ntau yam ntawm cov khoom siv oleate kuj tseem ceeb derivatives ntawm oleic acid.Raws li cov tshuaj reagent, nws tuaj yeem siv los ua cov qauv sib piv chromatographic thiab rau kev tshawb fawb biochemical, nrhiav kom tau calcium, tooj liab thiab magnesium, sulfur thiab lwm yam khoom.
Nws tuaj yeem siv rau kev tshawb fawb biochemical.Nws tuaj yeem qhib cov protein kinase C hauv daim siab hlwb.
Cov txiaj ntsig:
Oleic acid yog fatty acid uas muaj nyob rau hauv cov tsiaj thiab zaub roj.Oleic acid yog cov roj mono-saturated feem ntau ntseeg tias zoo rau ib tus neeg noj qab haus huv.Tseeb tiag, nws yog cov roj fatty acid uas muaj nyob hauv cov roj txiv roj, suav nrog 55 mus rau 85 feem pua ​​​​ntawm cov khoom tseem ceeb, uas feem ntau siv hauv Mediterranean cuisine thiab tau raug qhuas rau nws cov yam ntxwv kho mob txij thaum ancient sij hawm.Cov kev tshawb fawb niaj hnub no txhawb cov kev xav ntawm cov txiaj ntsig ntawm kev haus cov roj txiv roj, vim cov pov thawj qhia tias oleic acid pab txo qis qis lipoproteins tsawg (LDLs) hauv cov hlab ntsha, thaum tawm hauv cov qib siab lipoproteins (HDLs) tsis hloov.Pom muaj ntau ntau hauv canola, cod siab, txiv maj phaub, soybean, thiab almond roj, oleic acid tuaj yeem noj tau los ntawm ntau qhov chaw, qee qhov yuav sai sai no muaj ntau dua cov roj fatty acids vim kev siv zog ntawm caj ces. engineers.
Oleic acid tshwm sim ib txwm muaj ntau dua li lwm cov fatty acid.Nws yog tam sim no raws li glycerides nyob rau hauv feem ntau cov rog thiab roj.Cov ntsiab lus siab ntawm oleic acid tuaj yeem txo qis cov roj cholesterol.Nws yog siv nyob rau hauv kev lag luam khoom noj khoom haus los ua hluavtaws butters thiab cheeses.Nws kuj yog siv los tsw cov khoom ci, khoom qab zib, ice cream, thiab dej qab zib.
Raws li American Diabetes Association, ntau tshaj 25 lab tus neeg Asmeskas muaj ntshav qab zib.Tsis tas li ntawd, 7 lab muaj ntshav qab zib tsis tau kuaj pom, thiab 79 lab lwm tus muaj ntshav qab zib.Hauv kev tshawb fawb luam tawm thaum Lub Ob Hlis 2000 hauv phau ntawv kho mob "QJM," cov kws tshawb fawb hauv tebchaws Ireland pom tias cov khoom noj uas muaj oleic acid txhim kho cov neeg koom nrog kev yoo mov plasma qabzib, insulin rhiab heev thiab ntshav ncig.Txo cov piam thaj sai sai thiab qib insulin, nrog rau kev ua kom cov ntshav khiav zoo, qhia txog kev tswj ntshav qab zib kom zoo dua thiab tsis muaj kev pheej hmoo rau lwm yam kab mob.Rau ntau lab tus tib neeg uas kuaj mob ntshav qab zib thiab prediabetes, noj cov zaub mov uas nplua nuj nyob hauv oleic acid yuav muaj txiaj ntsig zoo los tswj tus kab mob.
