Oleic acid, Oleic acid, tseem hu ua cis-9-octadecenoic acid, yog cov khoom siv tshuaj lom neeg ntawm cov roj carboxylic tsis muaj roj thiab pom dav hauv cov roj tsiaj thiab zaub. Piv txwv li, roj txiv roj muaj li 82.6%; roj txiv laum huab xeeb muaj 60.0%; roj noob hnav muaj 47.4%; roj taum pauv muaj 35.5%; roj noob paj noob hlis muaj 34.0%; roj paj rwb muaj 33.0%; roj rapeseed muaj 23.9%; roj paj noob hlis muaj 18.7%; cov ntsiab lus hauv cov roj tshuaj yej tuaj yeem siab txog 83%; hauv cov roj tsiaj: roj roj lard muaj li 51.5%; butter muaj 46.5%; roj ntses loj muaj 34.0%; roj mis muaj 18.7%; Oleic acid muaj ob hom ruaj khov (α-hom) thiab tsis ruaj khov (β-hom). Thaum kub qis, nws tuaj yeem tshwm sim ua siv lead ua; thaum kub siab, nws tshwm sim ua kua roj tsis muaj xim pob tshab nrog tsw qab roj lard. Nws muaj qhov hnyav molecular ntawm 282.47, qhov ceev ntawm 0.8905 (20 ℃ kua), Mp ntawm 16.3 ° C (α), 13.4 ° C (β), qhov kub 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 txog 0.400 103 Pa), qhov ntsuas Refractive ntawm 1.4582 thiab viscosity ntawm 25.6 mPa • s (30 ° C).
Nws tsis yaj hauv dej, yaj hauv benzene thiab chloroform. Nws sib xyaw nrog methanol, ethanol, ether thiab carbon tetrachloride. Vim muaj ob txoj kev sib txuas, nws yooj yim raug cua oxidation, yog li ua rau muaj ntxhiab tsw phem nrog xim tig daj. Thaum siv nitrogen oxides, nitric acid, mercurous nitrate thiab sulfurous acid rau kev kho, nws tuaj yeem hloov mus rau elaidic acid. Nws tuaj yeem hloov mus rau stearic acid thaum hydrogenation. Ob txoj kev sib txuas yooj yim rau kev cuam tshuam nrog halogen los tsim halogen stearic acid. Nws tuaj yeem tau txais los ntawm hydrolysis ntawm cov roj txiv roj thiab cov roj lard, ua raws li kev sib xyaw ua ke thiab crystallization lossis rho tawm rau kev sib cais. Oleic acid yog cov kuab tshuaj zoo heev rau lwm cov roj, fatty acids thiab cov tshuaj yaj hauv roj. Nws tuaj yeem siv rau kev tsim cov xab npum, roj nplua nyeem, cov neeg sawv cev flotation, xws li tshuaj pleev thiab oleate.
Siv:
GB 2760-96 txhais nws ua ib yam khoom pab ua haujlwm. Nws siv tau ua tus neeg sawv cev tiv thaiv kev ua npuas dej, tshuaj tsw qab, cov khoom sib txuas, thiab cov roj nplua nyeem.
Nws tuaj yeem siv rau kev tsim cov xab npum, cov roj nplua nyeem, cov neeg sawv cev flotation, tshuaj pleev thiab oleate, kuj yog cov kuab tshuaj zoo heev rau cov roj fatty acids thiab cov roj-soluble substances.
Nws tuaj yeem siv rau kev txhuam kom meej ntawm kub, nyiaj thiab lwm yam hlau muaj nqis nrog rau kev txhuam hauv kev lag luam electroplating.
Nws tuaj yeem siv los ua cov tshuaj reagents, cov kuab tshuaj, cov roj nplua nyeem thiab cov neeg sawv cev flotation, tab sis kuj siv rau kev lag luam ua qab zib.
Oleic acid yog ib yam khoom siv organic chemical raw khoom thiab muaj peev xwm tsim tau epoxidized oleic acid ester tom qab epoxidation. Nws siv tau ua yas plasticizer thiab rau kev tsim cov azelaic acid los ntawm oxidation. Nws yog cov khoom siv raw ntawm polyamide resin. Tsis tas li ntawd, oleic acid kuj siv tau ua cov tshuaj tua kab emulsifier, luam ntawv thiab dyeing auxiliaries, industrial solvents, hlau minerals flotation agent, thiab tso tawm agent. Ntxiv mus, nws siv tau ua cov khoom siv raw rau kev tsim cov ntawv carbon, hlaws dai puag ncig thiab typing wax paper. Ntau hom oleate khoom kuj yog cov khoom tseem ceeb ntawm oleic acid. Ua ib qho tshuaj reagent, nws siv tau ua ib qho chromatographic comparative sample thiab rau kev tshawb fawb biochemical, nrhiav tau calcium, tooj liab thiab magnesium, sulfur thiab lwm yam ntsiab lus.
Nws siv tau rau kev tshawb fawb txog biochemical. Nws tuaj yeem ua kom cov protein kinase C hauv cov hlwb siab ua haujlwm.
Cov txiaj ntsig:
Oleic acid yog ib hom roj fatty acid uas pom muaj nyob rau hauv cov roj tsiaj thiab cov roj zaub. Oleic acid yog ib hom roj mono-saturated uas feem ntau ntseeg tias zoo rau ib tus neeg txoj kev noj qab haus huv. Tseeb tiag, nws yog cov roj fatty acid tseem ceeb uas pom muaj nyob rau hauv cov roj txiv roj, uas muaj li ntawm 55 txog 85 feem pua ​​ntawm cov khoom tseem ceeb, uas feem ntau siv rau hauv cov zaub mov Mediterranean thiab tau txais kev qhuas rau nws cov yam ntxwv kho mob txij li thaum ub los. Cov kev tshawb fawb niaj hnub no txhawb nqa lub tswv yim ntawm cov txiaj ntsig ntawm kev noj cov roj txiv roj, vim tias cov pov thawj qhia tias oleic acid pab txo cov roj lipoproteins tsawg-density (LDLs) uas ua rau muaj kev phom sij hauv cov ntshav, thaum tseem ua rau cov roj lipoproteins siab-density (HDLs) zoo tsis hloov pauv. Kuj pom muaj ntau hauv cov roj canola, daim siab cod, txiv maj phaub, taum pauv, thiab roj almond, oleic acid tuaj yeem noj tau los ntawm ntau qhov chaw, qee qhov yuav sai sai no muaj cov roj fatty acid ntau dua vim yog kev siv zog ntawm cov kws kho mob caj ces.
Oleic acid tshwm sim ntuj ntau dua li lwm cov fatty acid. Nws muaj nyob rau hauv cov glycerides feem ntau cov rog thiab roj. Cov concentration siab ntawm oleic acid tuaj yeem txo cov ntshav cov roj cholesterol. Nws yog siv rau hauv kev lag luam zaub mov los ua cov butters thiab cheeses. Nws kuj tseem siv los ua cov khoom ci, khoom qab zib, ice cream, thiab dej qab zib.
Raws li American Diabetes Association, muaj ntau tshaj 25 lab tus neeg Asmeskas muaj mob ntshav qab zib. Ntxiv rau, 7 lab tus neeg tsis tau kuaj pom tias muaj mob ntshav qab zib, thiab 79 lab tus neeg lwm tus muaj mob ua ntej mob 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 Ireland pom tias cov zaub mov nplua nuj hauv oleic acid tau txhim kho cov neeg koom nrog cov ntshav qab zib thaum noj mov, kev nkag siab ntawm insulin thiab kev ncig ntshav. Cov ntshav qab zib thiab insulin qis dua thaum noj mov, nrog rau kev ncig ntshav zoo dua, qhia txog kev tswj ntshav qab zib zoo dua thiab muaj kev pheej hmoo tsawg dua rau lwm yam kab mob. Rau ntau lab tus neeg uas tau kuaj pom tias muaj mob ntshav qab zib thiab ua ntej mob ntshav qab zib, kev noj cov zaub mov nplua nuj hauv oleic acid yuav pab tau rau kev tswj tus kab mob.
