Mea Hana Kumukūʻai Maikaʻi ʻOleic acid CAS: 112-80-1

ʻO ka waikawa Oleic, ʻo ka waikawa Oleic, i ʻike ʻia hoʻi ʻo cis-9-octadecenoic acid, nona nā waiwai kemika o ka waikawa carboxylic unsaturated hoʻokahi a hōʻike nui ʻia i loko o nā aila holoholona a me nā mea kanu. No ka laʻana, aia ma kahi o 82.6% ka ʻaila ʻoliva; aia ma kahi o 60.0% ka ʻaila pīnati; aia ma kahi o 47.4% ka ʻaila sesame; aia ma kahi o 35.5% ka ʻaila soybean; aia ma kahi o 34.0% ka ʻaila hua pua nānālā; aia ma kahi o 33.0% ka ʻaila pulupulu; aia ma kahi o 23.9% ka ʻaila rapeseed; aia ma kahi o 18.7% ka ʻaila safflower; hiki ke kiʻekiʻe ka nui o ka ʻaila kī i 83%; i loko o ka ʻaila holoholona: aia ma kahi o 51.5% ka ʻaila lard; aia ma kahi o 46.5% ka pata; aia ma kahi o 34.0% ka ʻaila kohola; aia ma kahi o 18.7% ka ʻaila kirīmi; Loaʻa i ka waikawa Oleic kahi ʻano paʻa (α-type) a me ka paʻa ʻole (β-type) ʻelua ʻano. I ka mahana haʻahaʻa, hiki ke ʻike ʻia he kristal; i ke ana wela kiʻekiʻe, ʻike ʻia ia he wai ʻaila ʻālohilohi kala ʻole me ke ʻala ʻaila poni. He 282.47 kona nui molekala pili, 0.8905 ka nui o ka wai (20 ℃), 16.3 ° C ka Mp (α), 13.4 ° C (β), ka paila ʻana he 286 °C (13.3 103 Pa), 225 a 226 °C (1.33 103 Pa), 203 a 205 °C (0.677 103 Pa), a me 170 a 175 °C (0.267 103 a 0.400 103 Pa), ʻo ka helu kuhikuhi Refractive he 1.4582 a me ka viscosity he 25.6 mPa • s (30 ° C).
He mea hoʻoheheʻe ʻole ia i ka wai, hiki ke hoʻoheheʻe ʻia i loko o ka benzene a me ka chloroform. Hiki ke hui pū ʻia me ka methanol, ethanol, ether a me ke kalapona tetrachloride. Ma muli o ka loaʻa ʻana o ka pilina pālua, hiki ke maʻalahi i ka oxidation ea, a laila e hana ana i kahi ʻala maikaʻi ʻole me ke kala e huli melemele. Ma ka hoʻohana ʻana i nā oxides nitrogen, ka waikawa nitric, ka nitrate mercurous a me ka waikawa sulfurous no ka mālama ʻana, hiki ke hoʻololi ʻia i ka waikawa elaidic. Hiki ke hoʻololi ʻia i ka waikawa stearic ma hope o ka hydrogenation. He maʻalahi ka pilina pālua e hana me ka halogen e hana i ka waikawa stearic halogen. Hiki ke loaʻa ma o ka hydrolysis o ka ʻaila ʻoliva a me ka ʻaila lard, a ukali ʻia e ka distillation mahu a me ka crystallization a i ʻole ka unuhi ʻana no ka hoʻokaʻawale ʻana. He mea hoʻoheheʻe maikaʻi loa ka waikawa Oleic no nā ʻaila ʻē aʻe, nā waikawa momona a me nā mea hiki ke hoʻoheheʻe ʻia i ka ʻaila. Hiki ke hoʻohana ʻia no ka hana ʻana i ke kopa, nā lubricants, nā mea flotation, e like me ka poni a me ka oleate.
Nā Hoʻohana:
Ua wehewehe ʻia e GB 2760-96 ia mea he mea kōkua hana. Hiki ke hoʻohana ʻia ma ke ʻano he mea antifoaming, ʻala, mea hoʻopaʻa, a me kahi lubricant.
Hiki ke hoʻohana ʻia no ka hana ʻana i ke kopa, nā lubricants, nā mea flotation, ka poni a me ka oleate, he mea hoʻoheheʻe maikaʻi loa hoʻi no nā waikawa momona a me nā mea hiki ke hoʻoheheʻe ʻia i ka ʻaila.
Hiki ke hoʻohana ʻia no ka wili pololei ʻana o ke gula, ke kālā a me nā metala makamae ʻē aʻe a me ka wili ʻana i ka ʻoihana electroplating.
Hiki ke hoʻohana ʻia e like me nā reagents loiloi, nā mea hoʻoheheʻe, nā lubricants a me ka mea flotation, akā pili pū ʻia i ka ʻoihana hana kō.
He mea maka kemika organik ka waikawa Oleic a hiki ke hana i ka ester oleic acid epoxidized ma hope o ka epoxidation. Hiki ke hoʻohana ʻia ma ke ʻano he plasticizer plastic a no ka hana ʻana o ka waikawa azelaic ma o ka oxidation. ʻO ia ka mea maka o ka resin polyamide. Eia kekahi, hiki ke hoʻohana ʻia ka waikawa oleic ma ke ʻano he emulsifier pesticide, nā mea kōkua paʻi a me ka dyeing, nā mea hoʻoheheʻe ʻoihana, ka mea flotation mineral metala, a me ka mea hoʻokuʻu. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he mea maka no ka hana ʻana i ka pepa kalapona, ka bead poepoe a me ka pepa wax typing. ʻO nā ʻano huahana oleate like ʻole he mau mea nui hoʻi o ka waikawa oleic. Ma ke ʻano he reagent kemika, hiki ke hoʻohana ʻia ma ke ʻano he laʻana hoʻohālikelike chromatographic a no ka noiʻi biochemical, ka ʻike ʻana i ka calcium, ke keleawe a me ka magnesium, ka sulfur a me nā mea ʻē aʻe.
Hiki ke hoʻopili ʻia i nā haʻawina biochemical. Hiki iā ia ke hoʻoulu i ka protein kinase C i loko o nā hunaola ake.
Nā Pōmaikaʻi:
ʻO ka waikawa Oleic kahi waikawa momona i loaʻa i loko o nā aila holoholona a me nā mea kanu. ʻO ka waikawa Oleic kahi momona mono-saturated i manaʻo nui ʻia he maikaʻi no ke olakino o ke kanaka. ʻOiaʻiʻo, ʻo ia ka waikawa momona nui i loaʻa i loko o ka ʻaila ʻoliva, nona ka 55 a 85 pakeneka o ka mea nui, ka mea i hoʻohana pinepine ʻia i ka meaʻai Mediterranean a ua hoʻomaikaʻi ʻia no kona ʻano therapeutic mai ka wā kahiko. Kākoʻo nā haʻawina hou i ka manaʻo o nā pono o ka ʻai ʻana i ka ʻaila ʻoliva, ʻoiai ke hōʻike nei nā hōʻike e kōkua ka waikawa oleic i ka hoʻohaʻahaʻa ʻana i nā pae o nā lipoproteins haʻahaʻa haʻahaʻa (LDLs) ʻino i loko o ke koko, ʻoiai e waiho ana i nā pae o nā lipoproteins kiʻekiʻe (HDLs) maikaʻi ʻaʻole i loli. Loaʻa pū kekahi i nā nui nui i loko o ka canola, cod ate, niu, soybean, a me nā ʻaila almond, hiki ke hoʻopau ʻia ka waikawa oleic mai nā kumu like ʻole, ʻo kekahi o ia mau mea e loaʻa koke ai nā pae kiʻekiʻe o ka waikawa momona waiwai ma muli o nā hana a nā ʻenekinia genetic.
Loaʻa maoli ka waikawa Oleic ma nā nui he nui ma mua o nā waikawa momona ʻē aʻe. Loaʻa ia ma ke ʻano he glycerides i ka hapa nui o nā momona a me nā aila. Hiki i nā nui kiʻekiʻe o ka waikawa oleic ke hoʻohaʻahaʻa i nā pae koko o ka cholesterol. Hoʻohana ʻia ia i ka ʻoihana meaʻai e hana i nā pata synthetic a me nā tīhi. Hoʻohana ʻia hoʻi ia e hoʻāla i nā mea i hoʻomoʻa ʻia, nā mea ʻono, ka ice cream, a me nā sodas.
Wahi a ka American Diabetes Association, ʻoi aku ma mua o 25 miliona mau ʻAmelika i loaʻa i ka maʻi diabetes. Eia kekahi, 7 miliona i loaʻa i ka maʻi diabetes i ʻike ʻole ʻia, a he 79 miliona mau mea ʻē aʻe i loaʻa i ka prediabetes. Ma kahi noiʻi i paʻi ʻia i Pepeluali 2000 ma ka puke pai lapaʻau "QJM," ua ʻike nā kānaka noiʻi ma Ireland ua hoʻomaikaʻi nā meaʻai waiwai i ka oleic acid i ka glucose plasma hoʻokē ʻai o nā mea komo, ka ʻike insulin a me ke kahe koko. ʻO ka haʻahaʻa o ka glucose hoʻokē ʻai a me ka insulin, me ka hoʻonui ʻia o ke kahe koko, e hōʻike ana i ka kaohi maikaʻi ʻana i ka maʻi diabetes a me ka emi ʻana o ka pilikia no nā maʻi ʻē aʻe. No nā miliona o ka poʻe i loaʻa i ka maʻi diabetes a me ka prediabetes, ʻo ka ʻai ʻana i nā meaʻai waiwai i ka oleic acid he mea maikaʻi paha ia i ka kaohi ʻana i ka maʻi.
