Honua - Premier Propylene Glycol: Ka Hui Organic Multifunctional

Nā Waiwai Kino a me nā Kemika

ʻAno a me ke ʻala: ʻIke ʻia ka propylene glycol ma ke ʻano he wai ʻole kala, moakāka, a mānoanoa. He ʻono iki kona a kokoke ʻole i ke ʻala, ʻo ia hoʻi he kūpono ia no nā noi kahi e pono ai kahi ʻano sensory kūlike ʻole.

Ka hoʻoheheʻe ʻana: Hōʻike ia i ka miscibility maikaʻi loa, hiki ke hui piha me ka wai, ethanol, ether, acetone, chloroform, a me nā mea hoʻoheheʻe organik ʻē aʻe he nui. ʻO kēia waiwai e hiki ai iā ia ke hana ma ke ʻano he mea hoʻoheheʻe a me ka emulsifier maikaʻi i nā ʻano like ʻole.

Nā Kūlana Kino Koʻikoʻi: Me ka nuipa molar o 76.09 g/mol, ʻo ka nui o ka propylene glycol ma kahi o 1.036 g/cm³ ma 25°C, ʻoi aku ka nui o ka wai. ʻO kona kiko heheʻe he - 59°C, e hiki ai iā ia ke noho i loko o kahi wai ma kahi ākea o ka mahana. Kū ka paila ma 188.2°C ma lalo o ke kaomi maʻamau, e hōʻike ana i kona kūpaʻa ma nā mahana maʻamau. He kiʻekiʻe iki ka kiko flash, ma kahi o 99°C (pani ʻia - kīʻaha), e hōʻemi ana i ka pilikia o ka hoʻā ʻana.

Ka Hana Kemika: Ma ke ʻano he diol, hiki i ka propylene glycol ke komo i nā ʻano hana kemika like ʻole o nā hui waiʻona. Hiki iā ia ke hana i nā esters ke hana ʻia me nā waikawa carboxylic, he mea nui ia i ka synthesis o nā huahana ʻoihana a me nā mea kūʻai aku. Eia kekahi, hiki iā ia ke hana i nā hopena dehydration ma lalo o nā kūlana kikoʻī, e alakaʻi ana i ka hoʻokumu ʻia ʻana o nā intramolecular cyclic ethers a i ʻole nā ​​​​polymers intermolecular.

Nā Wahi Hoʻohana

ʻOihana Meaʻai a me Mea Inu: He nui nā hana a ka Propylene glycol ma kēia ʻāpana. Hana ia ma ke ʻano he humectant, e kōkua ana i ka mālama ʻana i ka makū i loko o nā huahana meaʻai e like me nā mea i hoʻomoʻa ʻia, nā mea ʻono, a me nā mea waiū, no laila e hoʻolōʻihi ana i ko lākou ola papa a mālama i ke ʻano. Ma ke ʻano he mea hoʻoheheʻe, hoʻohana ʻia ia e hoʻoheheʻe i nā ʻono, nā kala, a me nā mea mālama, e hōʻoiaʻiʻo ana i ka hoʻolaha like ʻana i nā meaʻai a me nā mea inu. No ka laʻana, loaʻa pinepine ia i nā mea ʻono wai no nā mea inu palupalu a ma ke ʻano he mea lawe no nā aila koʻikoʻi i nā huahana meaʻai. Ua ʻae ʻia hoʻi ia he mea hoʻohui meaʻai (E1520) ma ka ʻAhahui ʻEulopa, a ua ʻike nui ʻia he palekana (GRAS) e ka US Food and Drug Administration (FDA) ke hoʻohana ʻia i loko o nā palena i kuhikuhi ʻia.

ʻOihana lāʻau lapaʻau: I loko o nā lāʻau lapaʻau, he kuleana koʻikoʻi ko ka propylene glycol. Hoʻohana nui ʻia ia ma ke ʻano he mea hoʻoheheʻe no nā lāʻau lapaʻau i maʻalahi ka hoʻoheheʻe ʻia i ka wai, e hoʻomaʻalahi ana i kā lākou hoʻohui ʻana i nā lāʻau lapaʻau waha, injectable, a me nā lāʻau lapaʻau topical. No ka laʻana, i loko o nā lāʻau lapaʻau waha wai he nui, kōkua ka propylene glycol i ka hoʻoheheʻe ʻana i nā mea hana lāʻau lapaʻau, e hōʻoiaʻiʻo ana i ka dosing pololei. I loko o nā hoʻohui topical e like me nā kirīmi a me nā poni, hana ia ma ke ʻano he humectant a me ka hoʻonui komo ʻana, e hoʻomaikaʻi ana i ka omo ʻana o ka ʻili i nā lāʻau lapaʻau. Loaʻa iā ia kekahi mau waiwai antibacterial a me antifungal, e kōkua ana i ka mālama ʻana i nā huahana lāʻau lapaʻau.

Nā mea hoʻonani a me ka mālama pilikino: He mea nui ka propylene glycol i loko o nā ʻano mea hoʻonani a me nā huahana mālama pilikino. I loko o nā huahana mālama ʻili e like me nā moisturizers, serums, a me nā mea hoʻomaʻemaʻe, hana ia ma ke ʻano he humectant, e huki ana i ka makū mai ka lewa a hoʻopaʻa iā ia i ka ʻili, a laila e mālama i ka ʻili i ka hydrated. ʻO kona mau waiwai solvent e hiki ai iā ia ke hoʻoheheʻe i nā mea hana like ʻole a me nā ʻala, e hōʻoia ana i ko lākou hoʻolaha like ʻana i nā huahana. Hoʻohana ʻia hoʻi ia i nā huahana mālama lauoho e like me nā shampoos a me nā conditioners e hoʻomaikaʻi i ko lākou ʻano a kōkua i ka lawe ʻana i nā mea pono i ke kumu lauoho. I loko o ka polish kui, hana ka propylene glycol ma ke ʻano he plasticizer, e pale ana i ka polish mai ka lilo ʻana i mea palupalu a me ka haki maʻalahi.

Nā Noi ʻOihana: He mea nui ka propylene glycol i ka hana ʻana o nā mea ʻoihana like ʻole. He mea maka koʻikoʻi ia i ka hana ʻana o nā resins polyester unsaturated, i hoʻohana nui ʻia i ka hana ʻana i nā plastics i hoʻoikaika ʻia me ka fiberglass. Loaʻa kēia mau plastics i nā noi ma nā ʻoihana e like me ke kaʻa, ke kūkulu ʻana, a me ke kai, ma muli o ko lākou ratio ikaika kiʻekiʻe i ke kaumaha a me ke kūpaʻa ʻana i ka pala. I ka ʻoihana kaʻa, hoʻohana ʻia nā ʻano antifreeze a me nā coolant i hoʻokumu ʻia me ka propylene glycol e hoʻoponopono i ka mahana o nā mīkini, e pale ana i ka wela nui a me ka hau ʻana. Hana pū ia ma ke ʻano he mea hoʻoheheʻe a me ka mea lawe i nā uhi, nā inika, a me nā mea hoʻopili, e hoʻonui ana i kā lākou hana a me nā waiwai noi.

Nā ʻAno Hoʻomākaukau

ʻO ka Hydrolysis Propane Epoxy: ʻO kēia kekahi o nā ʻano hana ʻoihana maʻamau. Ma kēia kaʻina hana, hana ka epoxy propane (propylene oxide) me ka wai i ke alo o kahi mea hoʻoulu. Hiki ke hana ka hopena ma lalo o nā kūlana like ʻole. Ma ke ʻano hydration wai pololei, hoʻohana ʻia ka mahana kiʻekiʻe (ma kahi o 150 - 200°C) a me ke kaomi (0.98 - 2.94 MPa), me ka ratio molar wai-a-epoxy propane ma kahi o 20. ʻOiai hiki i ka helu hoʻololi o ka epoxy propane i ka propylene glycol ke hiki i kahi o 85%, ua hana ʻia kekahi mau huahana polypropylene glycol. ʻO kekahi ala ʻē aʻe ʻo ia ka hydrolysis acid-catalyzed, kahi i hoʻohui ʻia ai kahi liʻiliʻi o ka mea hoʻoulu waikawa (e like me ka sulfuric acid). Hana ʻia ka hopena ma kahi mahana haʻahaʻa (50 - 70°C), a pono e hoʻopau ʻia ka huahana hopena a hoʻomaʻemaʻe ʻia ma o nā kaʻina hana e like me ka distillation vacuum e loaʻa ai ka propylene glycol maʻemaʻe kiʻekiʻe.

ʻO ka Hydrogenolysis Catalytic Glycerol: Hiki ke hoʻohana ʻia ʻo Glycerol ma ke ʻano he mea maka e hana ai i ka propylene glycol. Ma kēia ʻano hana, hana mua ʻo glycerol i ka protonation o kāna mau hui hydroxyl, a ukali ʻia e ka dehydration intramolecular e hana i nā huahana waena e like me nā enols a me keto - aldehyde tautomers. A laila hana kēia mau huahana waena i ka hydrogenation i ke alo o kahi mea hoʻoulu (e like me kahi mea hoʻoulu keleawe), a laila loaʻa ka 1,2 - propylene glycol. Loaʻa i kēia ʻano hana ka pono o ka hoʻohana ʻana i kahi feedstock hou (glycerol), hiki ke loaʻa mai nā kumu e like me ka hana biodiesel.

Nā Hana ʻenehana Biotechnological: Hiki ke hana ʻia kekahi mau microorganism, e like me kekahi mau ʻano bacteria a me ka hū, e hana i ka propylene glycol ma o nā kaʻina hana fermentation. No ka laʻana, ma ka hoʻololi ʻana i ka genetically Escherichia coli a i ʻole Klebsiella pneumoniae, hiki ke hana ʻia e hoʻololi i nā kō (e like me ka glucose) a i ʻole glycerol i propylene glycol. ʻOi aku ka launa o ke kaiapuni o kēia ʻano biotechnological i hoʻohālikelike ʻia me nā ʻano kemika kuʻuna, no ka mea, hana ia ma lalo o nā kūlana ʻoluʻolu a hiki ke hoʻohana i nā kumu kalapona hou. Eia nō naʻe, ʻo ka huahana a me ke kumukūʻai - pono o kēia mau ʻano he mau wahi ia o ka noiʻi ikaika a me ka hoʻomaikaʻi ʻana.

Nā Mālama

Nā Manaʻo Ola Kino: ʻOiai ua manaʻo ʻia ka propylene glycol he palekana no ka hoʻohana ʻana i ka meaʻai, nā lāʻau lapaʻau, a me nā mea hoʻonani i loko o nā palena i ʻae ʻia, hiki i ka ʻike kiʻekiʻe a i ʻole ka ʻai ʻana ke loaʻa nā hopena maikaʻi ʻole i ke olakino. ʻO ka ʻai ʻana i nā nui he nui e alakaʻi i nā hōʻailona e like me ka nausea, ka luaʻi ʻana, a me ka maʻi diarrhea. I nā hihia koʻikoʻi, hiki iā ia ke hana i ka metabolic acidosis, kahi kūlana kahi e hōʻiliʻili ai ke kino i ka nui o ka waikawa. ʻO ka pili ʻana o ka ʻili me ka propylene glycol i hoʻopaʻa ʻia e hoʻonāukiuki i kekahi poʻe, ʻoiai ka poʻe me ka ʻili koʻikoʻi. Pono e pale ʻia ka ʻike ʻana i ka ʻili no ka manawa lōʻihi a i ʻole ka hana hou ʻana. Ke hoʻohana ʻia i nā wahi ʻoihana, pono ka ea kūpono e pale aku i ka hanu ʻana i nā mahu propylene glycol, no ka mea, ʻo ka hanu kiʻekiʻe e hoʻoulu ai i ka ʻoluʻolu ʻole o ka hanu.

Nā Pōʻino Ahi a me ka Pahū: He mea lapalapa ka propylene glycol, ʻoiai he kiʻekiʻe kona kiko lapalapa. Hiki i kona mahu ke hana i nā hui pahū me ka ea ma lalo o kekahi mau kūlana. Pono e mālama ʻia nā wahi mālama a me ka lawelawe ʻana mai nā lapalapa ahi, nā huna ahi, a me nā kumu hoʻā ʻē aʻe. Pono e loaʻa nā ipu mālama pale ahi a me nā lako hoʻopau ahi kūpono ma nā wahi i mālama ʻia ai a hoʻohana ʻia paha ka propylene glycol.
Ka Hopena Kaiapuni: ʻOiai he biodegradable ka propylene glycol, hiki nō i ka hoʻokuʻu nui ʻana i ke kaiapuni, ʻoi aku hoʻi i loko o nā kino wai, ke loaʻa ka hopena. I loko o nā ʻōnaehana wai, hiki iā ia ke hoʻopau i ka oxygen i kona palaho ʻana, e hoʻopilikia ana paha i ke ola wai. No laila, pono e hoʻokō ʻia nā hana hoʻokele ʻōpala kūpono a me ka hoʻopaʻa ʻana e pale aku i ka hoʻokuʻu ʻole ʻia o ka propylene glycol i ke kaiapuni.
