Nā ʻano kino kino o ka hana Alkyl Polyglycosides-Phase

Pūnaehana binary

'Oko'a ke kaha ki'i o ka C12-14 alkyl polyglycoside (C12-14 APG)/ ʻōnaehana wai mai ka APG kaulahao pōkole.(Kiʻi 3).Ma nā haʻahaʻa haʻahaʻa, ua hoʻokumu ʻia kahi ʻāpana paʻa/wai ma lalo o ke kiko Krafft, ma luna o kahi ākea ākea.Me ka piʻi ʻana o ka mahana, hoʻololi ka ʻōnaehana i kahi pae wai isotropic.Ma muli o ka hoʻopaneʻe ʻana o ka crystallization i kahi nui, hoʻololi kēia palena ʻāpana i ke kūlana me ka manawa mālama.Ma nā haʻahaʻa haʻahaʻa, hoʻololi ke ʻano wai isotropic ma luna o 35 ℃ i ʻāpana ʻāpana ʻelua o nā pae wai ʻelua, e like me ka mea maʻamau me nā surfactants nonionic.Ma nā hoʻopaʻa ʻana ma luna o 60% ma ke kaupaona, hoʻokumu ʻia kahi kaʻina o ka māhele crystalline wai i nā mahana āpau.Pono e ʻōlelo ʻia ma ka ʻāpana ʻāpana isotropic hoʻokahi, hiki ke ʻike ʻia ka birefringence kahe e ʻike ʻia i ka wā e haʻahaʻa ai ka neʻe ʻana ma mua o ka māhele dissolved, a laila nalo koke ma hope o ka pau ʻana o ke kaʻina ʻā.Eia naʻe, ʻaʻohe wahi polyphase i ʻike ʻia e hoʻokaʻawale ʻia mai ka pae L1.Ma ka māhele L1, aia kahi ʻāpana ʻē aʻe me ka birefringence kahe ʻana ma kahi kokoke i ka waiwai haʻahaʻa o ka lua wai / wai miscibility.
Ua alakaʻi ʻia e Platz et al nā noiʻi Phenomenological i ke ʻano o nā ʻāpana crystalline wai.Ke hoʻohana nei i nā ʻano like me ka microscopy polarization.Ma hope o kēia mau noiʻi ʻana, ʻekolu mau ʻāpana lamellar ʻokoʻa i noʻonoʻo ʻia i loko o nā hoʻonā C12-14 APG: Lα_{l ,}Lα_lha me Lαh.Aia ʻekolu mau ʻano like ʻole e like me ka microscopy polarization.
Ma hope o ka mālama ʻia ʻana no ka manawa lōʻihi, hoʻomohala ka lamellar liquid crystalline phase i nā ʻāpana pseudoisotropic ʻeleʻele ma lalo o ke kukui polarized.Hoʻokaʻawale ʻia kēia mau wahi mai nā wahi birefringent loa.ʻO ka māhele Lαh, ka mea i loaʻa i loko o ka pae hoʻonaʻauao waena o ka māhele ʻāpana crystalline wai, ma nā wela kiʻekiʻe, e hōʻike ana i ia mau ʻano.ʻAʻole ʻike ʻia nā ʻano ʻano ʻo Schlieren, ʻoiai ʻo nā kaha ʻaila birefringent e loaʻa mau ana.Inā hoʻomaʻalili ʻia kahi laʻana i loko o kahi māhele Lαh no ka hoʻoholo ʻana i ke kiko Krafft, hoʻololi ke ʻano ma lalo o kahi wela ʻano.Nalo nā ʻāpana pseudoisotropic a me nā kaha ʻaila i wehewehe ʻia.I ka hoʻomaka, ʻaʻohe C12-14 APG crystallizes, akā, ua hoʻokumu ʻia kahi pae lyotropic hou e hōʻike ana i ka birefringence nāwaliwali.Ma nā haʻahaʻa kiʻekiʻe, hoʻonui kēia māhele i nā wela kiʻekiʻe.I ka hihia o nā alkyl glycosides, puka mai kahi ʻano ʻē aʻe. ʻO nā electrolytes a pau, koe ka sodium hydroxide, ua hopena i kahi hōʻemi nui o nā wahi ao. .He mea kupanaha, aia wale no ka li'ili'i li'ili'i ma waena o kēlā me kēia electrolytes. 'O ka ho'ohui 'ana o ka alkali i ho'emi nui 'ia ke ao.No ka wehewehe ʻana i nā ʻokoʻa ʻokoʻa ma waena o nā alkyl polyglycol ethers a me nā alkyl polyglycol ethers, ua manaʻo ʻia ua loaʻa i ka pūʻulu OH i hōʻiliʻili ʻia i loko o ka ʻāpana glucose i nā ʻano like ʻole o ka hydration me ka hui ethylene oxide.ʻO ka hopena ʻoi aku ka nui o nā electrolytes ma nā Alkyl polyglycol ethers e hōʻike ana aia kahi hoʻopiʻi ma ka ʻili o nā micelles alkyl polyglycoside, ʻoiai ʻaʻole i manaʻo ʻia nā alkyl polyethylene glycol ethers.
No laila, hana like nā alkyl polyglycosides e like me ka hui ʻana o nā alkyl polyglycol ethers a me nā mea hoʻoheheʻe anionic. ʻO ke aʻo ʻana i ka pilina ma waena o nā alkyl glycosides a me nā anionic a i ʻole cationic surfactants a me ka hoʻoholo ʻana o ka hiki i ka emulsion e hōʻike ana i nā micelles alkyl glycosides i ka ili maikaʻi ʻole i ka pH. ka laulā o 3 ~ 9. Ma ka hoʻohālikelike, ʻo ka hoʻopiʻi ʻana o ka alkyl polyethylene glycol ether micelles he nāwaliwali maikaʻi a kokoke paha i ka ʻole.ʻAʻole i wehewehe piha ʻia ke kumu i hoʻopiʻi ʻia ai nā micelles alkyl glycoside.
