Wopanga Mtengo Wabwino Oleic acid CAS:112-80-1

Oleic acid, Oleic acid, yomwe imadziwikanso kuti cis-9-octadecenoic acid, yokhala ndi mankhwala a single unsaturated carboxylic acid ndipo imapezeka kwambiri mumafuta anyama ndi masamba.Mwachitsanzo, mafuta a azitona ali ndi pafupifupi 82.6%;mafuta a mtedza ali ndi 60.0%;mafuta a sesame ali ndi 47.4%;mafuta a soya ali ndi 35.5%;mafuta a mpendadzuwa ali ndi 34.0%;mafuta a thonje ali ndi 33.0%;mafuta a rapeseed ali ndi 23.9%;mafuta a safflower ali ndi 18.7%;zomwe zili mu mafuta a tiyi zimatha kukhala 83%;mu mafuta anyama: mafuta anyama ali ndi pafupifupi 51.5%;batala lili 46.5%;mafuta a whale ali ndi 34.0%;mafuta a kirimu ali ndi 18.7%;Oleic asidi ali ndi khola (α-mtundu) ndi wosakhazikika (β-mtundu) mitundu iwiri.Pa kutentha kochepa, imatha kuwoneka ngati kristalo;Kutentha kwambiri, kumawoneka ngati madzi amafuta osawoneka bwino komanso onunkhira.Ili ndi kuchuluka kwa mamolekyu a 282.47, kachulukidwe wa 0.8905 (20 ℃ madzi), Mp wa 16.3 ° C (α), 13.4 ° C (β), kuwira kwa 286 ° C (13.3 103 Pa), 225 mpaka 226 °C(1.33 103 Pa), 203 mpaka 205 °C (0.677 103 Pa), ndi 170 mpaka 175 °C (0.267 103 mpaka 0.400 103 Pa), Refractive index of 1.4582 ndi viscosity ya 25.3 ° C • mPa ).
Sisungunuka m'madzi, kusungunuka mu benzene ndi chloroform.Imasakanikirana ndi methanol, ethanol, ether ndi carbon tetrachloride.Chifukwa chokhala ndi ma bond awiri, imatha kukhala ndi okosijeni wa mpweya mosavuta, motero imatulutsa fungo loyipa ndi mtundu wake kukhala wachikasu.Mukamagwiritsa ntchito ma nitrogen oxides, nitric acid, mercurous nitrate ndi sulfurous acid pochiza, amatha kusinthidwa kukhala elaidic acid.Ikhoza kusinthidwa kukhala stearic acid pa hydrogenation.Kugwirizana kwapawiri ndikosavuta kuchita ndi halogen kupanga halogen stearic acid.Itha kupezeka kudzera mu hydrolysis ya mafuta a azitona ndi mafuta anyama, ndikutsatiridwa ndi distillation ya nthunzi ndi crystallization kapena kuchotsa kwa kupatukana.Oleic acid ndi chosungunulira chabwino kwambiri chamafuta ena, mafuta acids ndi zinthu zosungunuka m'mafuta.Itha kugwiritsidwa ntchito popanga sopo, mafuta opangira mafuta, othandizira oyandama, monga mafuta odzola ndi oleate.
Zogwiritsa:
GB 2760-96 imatanthauzira ngati chithandizo chothandizira.Itha kugwiritsidwa ntchito ngati antifoaming wothandizira, kununkhira, binder, ndi mafuta.
Itha kugwiritsidwa ntchito popanga sopo, mafuta opangira mafuta, othandizira oyandama, mafuta odzola ndi oleate, kukhalanso chosungunulira chabwino kwambiri chamafuta acid ndi zinthu zosungunuka mafuta.
Itha kugwiritsidwa ntchito kupukuta ndendende golide, siliva ndi zitsulo zina zamtengo wapatali komanso kupukuta mumakampani opanga ma electroplating.
Itha kugwiritsidwa ntchito ngati reagents kusanthula, zosungunulira, mafuta ndi flotation wothandizira, komanso ntchito makampani processing shuga.
Oleic acid ndi organic mankhwala zopangira ndipo amatha kupanga epoxidized oleic acid ester pambuyo epoxidation.Itha kugwiritsidwa ntchito ngati plasticizer ndi kupanga azelaic acid ndi okosijeni.Ndi zopangira za polyamide resin.Kuphatikiza apo, oleic acid itha kugwiritsidwanso ntchito ngati emulsifier mankhwala, kusindikiza ndi utoto wothandizira, zosungunulira zamakampani, zitsulo zamchere zoyandama, komanso zotulutsa.Komanso, itha kugwiritsidwa ntchito ngati zopangira popanga pepala la kaboni, mikanda yozungulira komanso pepala la sera.Mitundu yosiyanasiyana ya zinthu za oleate ndizofunikiranso zochokera ku oleic acid.Monga reagent mankhwala, angagwiritsidwe ntchito ngati chromatographic kuyerekeza chitsanzo ndi kafukufuku biochemical, kuzindikira kashiamu, mkuwa ndi magnesium, sulfure ndi zinthu zina.
Ikhoza kugwiritsidwa ntchito pa maphunziro a biochemical.Imatha kuyambitsa puloteni kinase C m'maselo a chiwindi.
Ubwino:
Oleic acid ndi mafuta acid omwe amapezeka mumafuta anyama ndi masamba.Oleic acid ndi mafuta a mono-saturated omwe amakhulupirira kuti ndi abwino ku thanzi la munthu.Zoonadi, ndi mafuta a asidi omwe amapezeka m'mafuta a azitona, omwe ali ndi 55 mpaka 85 peresenti ya zinthu zofunika kwambiri, zomwe zimagwiritsidwa ntchito kwambiri pazakudya za ku Mediterranean ndipo zakhala zikuyamikiridwa chifukwa cha mankhwala ake kuyambira kalekale.Kafukufuku wamakono amathandizira lingaliro la ubwino wogwiritsa ntchito mafuta a azitona, popeza umboni umasonyeza kuti oleic acid imathandiza kuchepetsa ma lipoproteins otsika kwambiri (LDLs) m'magazi, ndikusiya milingo yopindulitsa ya high-density lipoproteins (HDLs) yosasinthika.Oleic acid imapezekanso mumafuta ambiri a canola, chiwindi cha cod, kokonati, soya ndi amondi, oleic acid imatha kudyedwa kuchokera kuzinthu zosiyanasiyana, zina zomwe posachedwapa zitha kukhala ndi mafuta ofunikira kwambiri chifukwa cha kuyesetsa kwa ma genetic. mainjiniya.
Oleic acid imapezeka mwachilengedwe mochulukirapo kuposa mafuta ena aliwonse.Amapezeka ngati glycerides m'mafuta ambiri ndi mafuta.Kuchuluka kwa oleic acid kumatha kutsitsa cholesterol m'magazi.Amagwiritsidwa ntchito m'makampani opanga zakudya kupanga mafuta opangira mafuta ndi tchizi.Amagwiritsidwanso ntchito kununkhira zinthu zowotcha, maswiti, ayisikilimu, ndi soda.
Malinga ndi American Diabetes Association, anthu aku America opitilira 25 miliyoni ali ndi matenda ashuga.Kuonjezera apo, 7 miliyoni ali ndi matenda a shuga omwe sanawazindikire, ndipo ena 79 miliyoni ali ndi matenda a shuga.Mu kafukufuku wofalitsidwa mu February 2000 mu nyuzipepala ya zachipatala "QJM," ofufuza ku Ireland adapeza kuti zakudya zokhala ndi oleic acid zimathandizira kusala shuga wa m'magazi a otenga nawo mbali, kukhudzidwa kwa insulini komanso kuyenda kwa magazi.Kutsika kwa shuga wamagazi ndi insulini, komanso kuwonjezereka kwa magazi, kumapereka kuwongolera kwabwino kwa shuga komanso kuchepa kwa chiwopsezo cha matenda ena.Kwa anthu mamiliyoni ambiri omwe ali ndi matenda a shuga komanso prediabetes, kudya zakudya zokhala ndi oleic acid kungakhale kopindulitsa popewera matendawa.
