Umkhiqizi Intengo Enhle I-Oleic acid CAS:112-80-1

I-Oleic acid, i-Oleic acid, eyaziwa nangokuthi i-cis-9-octadecenoic acid, iyingxenye yamakhemikhali e-single unsaturated carboxylic acid futhi yethulwa kabanzi emafutheni ezilwane nemifino.Isibonelo, amafutha omnqumo aqukethe cishe ama-82.6%;amafutha e-peanut aqukethe u-60.0%;amafutha e-sesame aqukethe u-47.4%;amafutha e-soya aqukethe u-35.5%;amafutha embewu kabhekilanga aqukethe u-34.0%;amafutha e-cottonseed aqukethe u-33.0%;amafutha e-rapeseed aqukethe u-23.9%;amafutha e-safflower aqukethe i-18.7%;okuqukethwe emafutheni etiye kungafinyelela ku-83%;emafutheni ezilwane: amafutha e-lard aqukethe cishe ama-51.5%;ibhotela iqukethe 46.5%;amafutha omkhomo aqukethe 34.0%;uwoyela ukhilimu uqukethe 18.7%;I-Oleic acid inezinhlobo ezimbili ezizinzile (α-type) kanye nezingaqinile (β-type).Ezingeni lokushisa eliphansi, lingavela njengekristalu;ekushiseni okuphezulu, kubonakala njengoketshezi olunamafutha angenalutho olungenambala olunephunga lesinqumelo.Inesisindo samangqamuzana esihlobene esingu-282.47, ukuminyana okuhlobene kuka-0.8905 (20 ℃ liquid), Mp of 16.3 ° C (α), 13.4 ° C (β), indawo yokubila engu-286 °C (13.3 103 Pa), 225 kuya ku-226 °C(1.33 103 Pa), 203 kuya ku-205 °C (0.677 103 Pa), kanye no-170 kuya ku-175 °C (0.267 103 kuya ku-0.400 103 Pa), inkomba ye-Refractive ye-1.4582 kanye ne-viscosity engu-25.3 ° C (mPa) ).
Ayincibiliki emanzini, iyancibilika ku-benzene ne-chloroform.Ixubene ne-methanol, i-ethanol, i-ether ne-carbon tetrachloride.Ngenxa yokuqukatha ibhondi ekabili, ingaba ngaphansi kwe-air oxidation kalula, ngaleyo ndlela ikhiqize iphunga elibi nombala ophenduka ophuzi.Lapho usebenzisa i-nitrogen oxides, i-nitric acid, i-mercurous nitrate kanye ne-sulfurous acid ekwelapheni, ingaguqulelwa ku-elaidic acid.Ingaguqulwa ibe yi-stearic acid phezu kwe-hydrogenation.Isibopho esiphindwe kabili kulula ukusabela nge-halogen ukukhiqiza i-halogen stearic acid.Ingatholakala nge-hydrolysis yamafutha omnqumo namafutha e-lard, kulandelwa i-steam distillation kanye ne-crystallization noma isizinda sokuhlukaniswa.I-Oleic acid iyi-solvent enhle kakhulu kwamanye amafutha, ama-fatty acids kanye nezinto ezincibilika uwoyela.Ingasetshenziselwa ukwenziwa kwensipho, okothambisa, ama-flotation agents, njengamafutha kanye ne-oleate.
Isebenzisa:
I-GB 2760-96 iyichaza njengosizo lokucubungula.Ingasetshenziswa njenge-ejenti ye-antifoaming, iphunga, i-binder, kanye ne-lubricant.
Ingasetshenziselwa ukwakhiwa kwensipho, okothambisa, ama-flotation agents, amafutha okugcoba kanye ne-oleate, okuphinde kube isixazululi esihle kakhulu sama-acids anamafutha kanye nezinto ezincibilika uwoyela.
Ingasetshenziselwa ukupholishwa okunembile kwegolide, isiliva nezinye izinsimbi eziyigugu kanye nokupholisha embonini ye-electroplating.
Ingasetshenziswa njengama-reagents okuhlaziya, ama-solvents, ama-lubricant kanye ne-ejenti ye-flotation, kodwa futhi isetshenziswe embonini yokucubungula ushukela.
I-Oleic acid iyi-organic chemical material eluhlaza futhi ingakhiqiza i-oleic acid ester epoxidized ngemva kwe-epoxidation.Ingasetshenziswa njenge-plasticizer yepulasitiki kanye nokukhiqizwa kwe-azelaic acid nge-oxidation.Yimpahla eluhlaza ye-polyamide resin.Ngaphezu kwalokho, i-oleic acid ingasetshenziswa futhi njenge-emulsifier yesibulala-zinambuzane, izinsiza zokuphrinta nokudaya, izincibilikisi zezimboni, i-ejenti yensimbi yokuntanta kwamaminerali, kanye ne-ejenti yokukhulula.Ngaphezu kwalokho, ingasetshenziswa njengezinto zokusetshenziswa zokwenziwa kwephepha lekhabhoni, ubuhlalu obuyindilinga nokuthayipha iphepha le-wax.Izinhlobo ezahlukahlukene zemikhiqizo ye-oleate nazo ziyizinto ezibalulekile ze-oleic acid.Njenge-reagent yamakhemikhali, ingasetshenziswa njengesampula yokuqhathanisa i-chromatographic kanye nokucwaninga kwamakhemikhali ezinto eziphilayo, ukutholwa kwe-calcium, ithusi ne-magnesium, isulfure nezinye izakhi.
Ingasetshenziswa ezifundweni ze-biochemical.Ingenza kusebenze i-protein kinase C kumaseli esibindi.
Izinzuzo:
I-Oleic acid i-fatty acid etholakala emafutheni ezilwane nemifino.I-Oleic acid ingamafutha ane-mono-saturated ngokuvamile okukholakala ukuthi alungele impilo yomuntu.Ngempela, iyi-acid eyinhloko enamafutha atholakala emafutheni omnqumo, ehlanganisa amaphesenti angu-55 kuya kwangu-85 ento ebalulekile, evame ukusetshenziswa ezitsheni zaseMedithera futhi ibilokhu inconywa ngezici zayo zokwelapha kusukela kudala.Ucwaningo lwesimanje lusekela umbono wezinzuzo zokusetshenziswa kwamafutha omnqumo, njengoba ubufakazi bubonisa ukuthi i-oleic acid isiza amazinga aphansi e-low-density lipoproteins (LDLs) ayingozi egazini, kuyilapho ishiya amazinga anenzuzo aphezulu-high-density lipoproteins (HDLs) engashintshiwe.Itholakala futhi ngamanani abalulekile ku-canola, isibindi se-cod, ukhukhunathi, ubhontshisi wesoya, namafutha e-alimondi, i-oleic acid ingadliwa emithonjeni ehlukahlukene, eminye yayo engase ibe namazinga aphakeme ngisho nangaphezulu amafutha abalulekile ngenxa yemizamo yofuzo. onjiniyela.
I-Oleic acid yenzeka ngokwemvelo ngamanani amakhulu kunanoma iyiphi enye i-acid enamafutha.Ikhona njenge-glycerides emafutheni amaningi nasemafutheni.Ukugxila okuphezulu kwe-oleic acid kunganciphisa amazinga egazi we-cholesterol.Isetshenziswa embonini yokudla ukwenza amabhotela okwenziwa kanye noshizi.Ibuye isetshenziselwe ukunambitheka izinto ezibhakwayo, uswidi, u-ayisikhilimu, namasoda.
Ngokusho kwe-American Diabetes Association, bangaphezu kwezigidi ezingama-25 abantu baseMelika abanesifo sikashukela.Ngaphezu kwalokho, abayizigidi ezingu-7 banesifo sikashukela esingatholakali, kanti abanye abayizigidi ezingu-79 bane-prediabetes.Ocwaningweni olwanyatheliswa ngoFebhuwari 2000 kujenali yezokwelapha "QJM," abacwaningi base-Ireland bathola ukuthi ukudla okunothe nge-oleic acid kuthuthukisa ukuzila kweglucose ye-plasma yabahlanganyeli, ukuzwela kwe-insulin nokujikeleza kwegazi.Ukwehla kweglucose yokuzila ukudla namazinga e-insulin, kanye nokugeleza kwegazi okuthuthukisiwe, kuphakamisa ukulawulwa okungcono kwesifo sikashukela kanye nobungozi obuncane kwezinye izifo.Ezigidini zabantu abatholakala benesifo sikashukela kanye ne-prediabetes, ukudla ukudla okunothe nge-oleic acid kungase kube yinzuzo ekulawuleni lesi sifo.
