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

Oleic acid, Oleic acid, yomwe imadziwikanso kuti cis-9-octadecenoic acid, yokhala ndi mankhwala ofanana ndi single unsaturated carboxylic acid ndipo imapezeka kwambiri mumafuta a nyama ndi ndiwo zamasamba. 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 mbewu ya 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 kufika 83%; mu mafuta a nyama: mafuta a batala ali ndi pafupifupi 51.5%; batala ali ndi 46.5%; mafuta a whale ali ndi 34.0%; mafuta a kirimu ali ndi 18.7%; Oleic acid ili ndi mitundu iwiri yokhazikika (α-type) ndi yosakhazikika (β-type). Pa kutentha kochepa, imatha kuwoneka ngati kristalo; Pa kutentha kwakukulu, imawoneka ngati madzi amafuta owonekera opanda mtundu komanso fungo la mafuta anyama. Ili ndi kulemera kwa mamolekyulu a 282.47, kuchuluka kwa 0.8905 (20 ℃ madzi), Mp wa 16.3 ° C (α), 13.4 ° C (β), kutentha kotentha 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 ya 1.4582 ndi viscosity ya 25.6 mPa • s (30 ° C).
Sisungunuka m'madzi, imasungunuka mu benzene ndi chloroform. Imasakanikirana ndi methanol, ethanol, ether ndi carbon tetrachloride. Chifukwa chokhala ndi ma bond awiri, imatha kusungunuka mosavuta mu mpweya, zomwe zimapangitsa fungo loipa ndi mtundu kukhala wachikasu. Mukagwiritsa ntchito ma nitrogen oxides, nitric acid, mercurous nitrate ndi sulfurous acid pochiza, imatha kusinthidwa kukhala elaidic acid. Itha kusinthidwa kukhala stearic acid ikapangidwa ndi hydrogenation. Ma bond awiri ndi osavuta kuchita ndi halogen kuti apange halogen stearic acid. Itha kupezeka kudzera mu hydrolysis ya mafuta a azitona ndi mafuta anyama, kutsatiridwa ndi kusungunuka kwa nthunzi ndi crystallization kapena kuchotsa kuti ilekanitsidwe. Oleic acid ndi solvent yabwino kwambiri ya mafuta ena, mafuta acids ndi zinthu zosungunuka mu mafuta. Itha kugwiritsidwa ntchito popanga sopo, mafuta odzola, zinthu zoyandama, monga mafuta odzola ndi oleate.
Ntchito:
GB 2760-96 imafotokoza kuti ndi chinthu chothandizira kukonza zinthu. Ingagwiritsidwe ntchito ngati choletsa thovu, fungo, chomangira, komanso chopaka mafuta.
Ingagwiritsidwe ntchito popanga sopo, mafuta odzola, zinthu zodulira, mafuta odzola ndi oleate, komanso ndi njira yabwino kwambiri yosungunulira mafuta acid ndi zinthu zosungunuka ndi mafuta.
Itha kugwiritsidwa ntchito popukuta bwino golide, siliva ndi zitsulo zina zamtengo wapatali komanso kupukuta m'makampani opanga ma electroplating.
Itha kugwiritsidwa ntchito ngati zinthu zoyezera kusanthula, zosungunulira, mafuta odzola ndi zinthu zoyezera kuyandama, komanso imagwiritsidwanso ntchito mumakampani opanga shuga.
Oleic acid ndi mankhwala opangidwa ndi organic ndipo amatha kupanga ester ya oleic acid yomwe imasungunuka mu oxygen pambuyo pa epoxidation. Itha kugwiritsidwa ntchito ngati pulasitiki wothira pulasitiki komanso popanga azelaic acid ndi okosijeni. Ndi zinthu zopangira polyamide resin. Kuphatikiza apo, oleic acid ingagwiritsidwenso ntchito ngati emulsifier ya mankhwala ophera tizilombo, othandizira kusindikiza ndi kupaka utoto, zosungunulira zamakampani, othandizira kuyandama kwa mchere wachitsulo, komanso othandizira kutulutsa. Kuphatikiza apo, itha kugwiritsidwanso ntchito ngati zinthu zopangira mapepala a kaboni, bead yozungulira ndi pepala la sera lolemba. Mitundu yosiyanasiyana ya zinthu zopangidwa ndi oleate ndi zinthu zofunika kwambiri zochokera ku oleic acid. Monga reagent ya mankhwala, itha kugwiritsidwa ntchito ngati chitsanzo choyerekeza cha chromatographic komanso kafukufuku wa biochemical, kuzindikira calcium, mkuwa ndi magnesium, sulfure ndi zinthu zina.
Ingagwiritsidwe ntchito pa maphunziro a biochemical. Ikhoza kuyambitsa protein kinase C m'maselo a chiwindi.
Ubwino:
Asidi wa Oleic ndi mafuta opezeka m'mafuta a nyama ndi ndiwo zamasamba. Asidi wa Oleic ndi mafuta okhuta omwe nthawi zambiri amaonedwa kuti ndi abwino pa thanzi la munthu. Inde, ndiye mafuta ochulukirapo omwe amapezeka m'mafuta a azitona, omwe amakhala ndi 55 mpaka 85 peresenti ya chinthu chofunikira, chomwe chimagwiritsidwa ntchito kwambiri mu zakudya za ku Mediterranean ndipo chayamikiridwa chifukwa cha makhalidwe ake ochiritsira kuyambira kalekale. Kafukufuku wamakono akuchirikiza lingaliro la ubwino wodya mafuta a azitona, popeza umboni ukusonyeza kuti asidi wa Oleic amathandiza kuchepetsa kuchuluka kwa lipoproteins zotsika kwambiri (LDLs) m'magazi, pomwe amasiya kuchuluka kwa lipoproteins zopindulitsa (HDLs) zosasinthika. Amapezekanso mochuluka mu mafuta a canola, chiwindi cha cod, kokonati, soya, ndi amondi, asidi wa Oleic amatha kudyedwa kuchokera kuzinthu zosiyanasiyana, zina zomwe posachedwa zitha kukhala ndi mafuta ochulukirapo chifukwa cha khama la mainjiniya a majini.
Asidi wa oleic amapezeka mwachilengedwe mochuluka kuposa asidi wina aliyense wamafuta. Amapezeka ngati glycerides m'mafuta ndi mafuta ambiri. Kuchuluka kwa oleic acid kumatha kuchepetsa kuchuluka kwa cholesterol m'magazi. Amagwiritsidwa ntchito mumakampani opanga chakudya popanga batala ndi tchizi. Amagwiritsidwanso ntchito kununkhira zakudya zophikidwa, maswiti, ayisikilimu, ndi soda.
Malinga ndi bungwe la American Diabetes Association, anthu oposa 25 miliyoni aku America ali ndi matenda a shuga. Kuphatikiza apo, anthu 7 miliyoni ali ndi matenda a shuga omwe sanadziwike, ndipo ena 79 miliyoni ali ndi matenda a shuga omwe sanadziwike. Mu kafukufuku wofalitsidwa mu February 2000 mu magazini ya zamankhwala "QJM," ofufuza ku Ireland adapeza kuti zakudya zokhala ndi oleic acid zambiri zimathandizira kuti shuga m'magazi a anthu omwe ali ndi matenda a shuga ayambe kusala kudya, insulin isamayende bwino komanso magazi ayambe kuyenda bwino. Kuchepetsa shuga m'magazi ndi insulin m'magazi, komanso kuwonjezeka kwa magazi, kumasonyeza kuti matenda a shuga amatha kulamulidwa bwino komanso kuchepetsa chiopsezo cha matenda ena. Kwa anthu mamiliyoni ambiri omwe ali ndi matenda a shuga komanso matenda a shuga omwe sanadziwike, kudya zakudya zokhala ndi oleic acid kungakhale kothandiza poletsa matendawa.
