Umenzi Ixabiso Elilungileyo I-Oleic acid CAS: 112-80-1

inkcazelo emfutshane:

I-Oleic acid : I-Oleic acid luhlobo lwe-asidi enamafutha angaxutywanga kunye nesakhiwo sayo se-molecular equkethe i-carbon-carbon double bond, ibe yi-acid enamafutha eyenza i-olein. Yenye yezona zinto zibanzi zendalo ze-unsaturated fatty acids. I-oil lipid hydrolysis ingakhokelela kwi-oleic acid kunye nefomula yekhemikhali CH3 (CH2) 7CH = CH (CH2) 7 • COOH. I-glyceride ye-oleic acid yenye yezinto eziphambili zeoli yeoli, ioli yesundu, i-lard kunye nezinye izilwanyana kunye nemifuno yeoli. Iimveliso zayo zoshishino zihlala ziqulethe i-7 ~ 12% ye-fatty acids egcweleyo (i-palmitic acid, i-stearic acid) kunye nenani elincinci lezinye i-unsaturated fatty acids (i-linoleic acid). Lulwelo olunamafutha angenambala kunye nomxhuzulane okhethekileyo ngu-0.895 (25/25 ℃), indawo yokukhenkceza ye-4 ℃, indawo yokubila eyi-286 °C (13,332 Pa), kunye nesalathiso se-refractive se-1.463 (18 ° C).

Inkcazo

Ixabiso layo le-iodine li-89.9 kwaye ixabiso layo le-asidi yi-198.6. Ayinyibiliki emanzini, kodwa inyibilika etywaleni, benzene, chloroform, ether kunye nenye ioyile eguquguqukayo okanye i-oyile esisigxina. Yakuba sesichengeni somoya, ngakumbi xa iqulethe ukungcola okuthile, ichaphazeleka kwi-oxidation kunye nombala wayo ojika ube tyheli okanye omdaka, kunye nevumba elibi. Kuxinzelelo oluqhelekileyo, luya kuba phantsi kokubola kwe-80 ~ 100 °C. Yenziwa nge-saponification kunye ne-asidi yezilwanyana kunye nemifuno yeoli. I-Oleic acid sisondlo esiyimfuneko ekutyeni kwezilwanyana. Ityuwa yayo yelothe, ityuwa yemanganese, ityuwa yecobalt yeyezixhobo zokomisa ipeyinti; ityuwa yayo yobhedu ingasetyenziswa njengezithinteli zenethi yeentlanzi; ityuwa yayo aluminiyam ingasetyenziswa njengesixhobo sokugxotha amanzi kwilaphu kwakunye nokujiya kwezinye izithambiso. Xa i-epoxidized, i-oleic acid inokuvelisa i-epoxy oleate (iplastiki). Ekuxhomekeke ekuqhekekeni kwe-oxidative, inokuvelisa i-azelaic acid (izinto eziluhlaza ze-polyamide resin). Inokutywinwa. Yigcine ebumnyameni.
I-Oleic acid ikhona kwisilwanyana kunye nemifuno yeoli yamafutha kwisixa esikhulu, ngokuyininzi ikwimo ye-glyceride. Ezinye ii-oleic esters ezilula zinokusetyenziswa kwilaphu, ufele, izithambiso kunye namashishini axuba amayeza. Ityuwa yesinyithi yealkali ye-oleic acid inokunyibilika emanzini, ibe yenye yezinto eziphambili zesepha. Ilothe, ubhedu, i-calcium, i-mercury, i-zinc kunye nezinye iityuwa ze-oleic acid zinyibilika emanzini. Ingasetyenziselwa njengezithambiso ezomileyo, i-agent yokomisa ipeyinti kunye ne-agent yokukhusela amanzi.
I-Oleic acid ikakhulu ivela kwindalo. Amafutha e-oyile aqulethe umxholo ophezulu we-oleic acid, emva kokuthobela i-saponification kunye nokwahlukana kwe-acidification, inokuvelisa i-oleic acid. I-Oleic acid ine-cis-isomers. I-oleic acids yendalo yonke i-cis-structure (i-trans-structure oleic acid ayikwazi ukufunxwa ngumzimba womntu) kunye nefuthe elithile lokuthambisa imithambo yegazi. Ikwadlala indima ebalulekileyo kwinkqubo yemetabolism yabantu kunye nezilwanyana. Nangona kunjalo, i-oleic acid eyenziwe ngumzimba womntu ngokwawo ayikwazi ukuhlangabezana neemfuno, ngoko sifuna ukutya. Ke, ukusetyenziswa kweoyile etyiwayo ephezulu ye-oleic acid isempilweni.

Ukusetyenziswa kwe-Oleic acid

I-Oleic acid, i-Oleic acid, ekwabizwa ngokuba yi-cis-9-octadecenoic acid, ineepropathi zekhemikhali ze-carboxylic acid enye engafakwanga kwaye ibonakaliswe ngokubanzi kwi-oyile yezilwanyana kunye nemifuno. Ngokomzekelo, ioli yeoli iqulethe malunga ne-82.6%; ioli ye-peanut iqulethe i-60.0%; ioli yeesame iqulethe i-47.4%; ioli yeembotyi zesoya iqulethe i-35.5%; ioli yembewu yejongilanga iqulethe i-34.0%; ioli ye-cottonseed iqulethe i-33.0%; ioli ye-rapeseed iqulethe i-23.9%; ioli ye-safflower iqulethe i-18.7%; umxholo kwi-oyile yeti ingaba phezulu njenge-83%; kwioli yezilwanyana: ioli ye-lard iqulethe malunga ne-51.5%; ibhotolo iqulethe 46.5 %; ioli yomnenga iqulethe i-34.0%; ioli ekhilimu iqulethe i-18.7%; I-Oleic acid ine-stable (α-type) kunye ne-stable (β-type) ezimbini iintlobo. Kwiqondo lokushisa eliphantsi, linokuvela njengekristale; kwiqondo lobushushu eliphezulu, ibonakala njengolwelo oluneoli olungenambala olungenambala olunevumba lamafutha arhabaxa. Inobunzima bemolekyuli obuyi-282.47, ukuxinana kwe-0.8905 (20 ℃ ulwelo), Mp ye-16.3 ° C (α), 13.4 ° C (β), indawo yokubilisa ye-286 ° C (13.3 103 Pa), 225 ukuya ku-226 ° C (03 ° C (03 ° C) ukuya ku-233 (03 ° C) 1 ukuya ku-233 (1.3 ukuya ku-2) (0.677 103 Pa), kunye ne-170 ukuya kwi-175 ° C (0.267 103 ukuya ku-0.400 103 Pa), i-index Refractive ye-1.4582 kunye ne-viscosity ye-25.6 mPa • s (30 ° C).
Ayinyibiliki emanzini, kwaye iyanyibilika kwibenzene nakwiklorofomu. Ixutywe kunye ne-methanol, i-ethanol, i-ether kunye ne-carbon tetrachloride. Ngenxa yokuqulatha ibhondi ephindwe kabini, inokuxhomekeka ngokulula kwi-oxidation yomoya, ngaloo ndlela ivelise ivumba elibi nombala ojika ube tyheli. Emva kokusebenzisa i-nitrogen oxides, i-nitric acid, i-mercurous nitrate kunye ne-sulfurous acid kunyango, inokuguqulwa ibe yi-elaidic acid. Inokuguqulwa ibe yi-stearic acid xa i-hydrogenation. Ukudibanisa kabini kulula ukusabela kunye ne-halogen ukuvelisa i-halogen stearic acid. Inokufumaneka nge-hydrolysis yeoli yeoli kunye neoli ye-lard, ilandelwa yi-distillation ye-steam kunye ne-crystallization okanye i-extraction yokwahlula. I-Oleic acid sisinyibilikisi esigqwesileyo sezinye ioyile, iiasidi ezinamafutha kunye nezinto ezinyibilikayo kwi-oyile. Ingasetyenziselwa ukwenziwa kwesepha, izinto zokuthambisa, iiarhente ezidadayo, ezifana ne-ointment kunye ne-oleate.

Izibonelelo:
I-Oleic acid yi-asidi enamafutha efumaneka kwi-oyile yezilwanyana kunye nemifuno. I-Oleic acid ngamafutha ane-mono-saturated ngokubanzi ekukholelwa ukuba alungile kwimpilo yomntu. Enyanisweni, yeyona asidi ephambili efumaneka kwioli yomnquma, equka ama-55 ukuya kuma-85 ekhulwini ezinto ezibalulekileyo, ezisetyenziswa ngokuqhelekileyo kukutya kweMeditera yaye kuye kwanconywa ngenxa yeempawu zayo zonyango ukususela kwamandulo. Izifundo zanamhlanje zixhasa ingcamango yeenzuzo zokusebenzisa ioli yeoli, ekubeni ubungqina bubonisa ukuba i-oleic acid inceda amanqanaba asezantsi e-low-density lipoproteins (LDLs) eyingozi egazini, ngelixa eshiya amanqanaba e-high-density lipoproteins (HDLs) enenzuzo engatshintshi. Ifumaneka nakwizixa ezibalulekileyo kwicanola, isibindi secod, ikhokhonathi, iimbotyi zesoya, kunye neoyile yealmondi, iasidi yeoleic inokutyiwa kwimithombo eyahlukeneyo, eminye yayo enokuthi kungekudala iqulathe amanqanaba aphezulu exabiso leasidi enamafutha ngenxa yemigudu yeenjineli zemfuza.
Iasidi ye-Oleic yenzeka ngokwendalo ngobuninzi obukhulu kunayo nayiphi na enye iasidi enamafutha. Ikhona njenge glycerides kumafutha amaninzi kunye namafutha. Ukugxilwa okuphezulu kwe-oleic acid kunokunciphisa amanqanaba egazi le-cholesterol. Isetyenziswa kwishishini lokutya ukwenza iibhotolo zokwenziwa kunye neetshizi. Ikwasetyenziselwa ukungcamla izinto ezibhakiweyo, iilekese, i-ayisikrimu, kunye neesoda.
Ngokutsho kwe-American Diabetes Association, ngaphezu kwe-25 yezigidi zabantu baseMelika banesifo seswekile. Ukongezelela, abantu abazizigidi ezisi-7 banesifo seswekile esingafunyaniswanga, yaye abanye abazizigidi ezingama-79 baneprediabetes. Kuphononongo olupapashwe ngoFebruwari 2000 kwiphepha lezonyango "QJM," abaphandi base-Ireland bafumanisa ukuba ukutya okucebileyo kwi-oleic acid kuphucule abathathi-nxaxheba be-plasma glucose, ukuvalelwa kwe-insulin kunye nokujikeleza kwegazi. Ukuzila ukutya okuphantsi kwe-glucose kunye namanqanaba e-insulin, kunye nokuhamba kwegazi okuphuculweyo, kubonisa ukulawula okungcono kwesifo sikashukela kunye nomngcipheko omncinci wezinye izifo. Kwizigidi zabantu abanesifo seswekile kunye ne-prediabetes, ukutya ukutya okutyebileyo kwi-oleic acid kunokuba luncedo ekulawuleni esi sifo.
