Ma ke kahua o ke kemika, ʻo kekahi mau hui organik, ma muli o ko lākou mau ʻano he hiki ʻole ke hoʻoheheʻe ʻia a hoʻoheheʻe iki ʻia paha i ka wai, lawe mai i nā pilikia he nui i nā noi hana. Eia nō naʻe, i ka wā e hui pū ai kēia mau hui organik me nā surfactants, piʻi nui ko lākou solubility, kahi hanana i ʻike ʻia ʻo solubilization. Hana nā Surfactants ma ke ʻano he solubilizers i kēia kaʻina hana, ʻoiai ʻo nā hui organik e solubilized ʻia ua kapa ʻia ʻo solubilizates. E luʻu kēia ʻatikala i loko o ke ʻano o ka solubilization a me kāna mau mea hoʻohuli.
1. ʻAno hana o ka hoʻoheheʻe ʻana
Pili loa ka hanana o ka solubilization i nā waiwai o nā surfactants. Ua hōʻike ʻia nā hoʻokolohua i ka wā e haʻahaʻa ai ka nui o nā surfactants ma mua o ka nui o nā micelle koʻikoʻi (CMC), ʻaʻole loli nui ka solubility o nā mea olaola; akā naʻe, i ka wā e ʻoi aku ai ka nui o ka CMC, piʻi nui ka solubility. ʻO kēia no ka mea ma kēia nui, hoʻomaka nā surfactants e hana i nā micelles, a pili loa ka solubilization i ka hoʻokumu ʻia ʻana o nā micelles.
Ma muli o ke kūlana o ka mea i hoʻoheheʻe ʻia i loko o ka micelle, ʻehā mau ala nui o ka hoʻoheheʻe ʻana:
①Hoʻoheheʻe ʻia i loko o ka micelle: He kūpono kēia ʻano hana no nā mea hydrocarbon non-polar maʻalahi, e like me benzene, ethylbenzene, a me n-heptane. He maʻalahi lākou e hoʻoheheʻe ʻia i loko o ka micelle no ka mea hiki ke manaʻo ʻia ka loko o ka micelle he hui hydrocarbon maʻemaʻe, nona nā ʻano like me kēia mau mea.
②Ka hoʻoheheʻe ʻia ʻana i loko o ka papa micelle palisade: No nā mea olaola polar e like me nā waiʻona kaulahao lōʻihi a me nā waikawa, ua hoʻolaha ʻia lākou ma ke ʻano ʻē aʻe a ma ke ʻano like me nā molekala surfactant. Hoʻopili nā ʻāpana non-polar me nā hui hydrophobic o nā surfactants ma o nā ikaika van der Waals, ʻoiai ua pili nā ʻāpana polar i nā hui hydrophilic o nā surfactants ma o nā ikaika van der Waals a me nā pilina hydrogen.
③Ka hoʻoheheʻe ʻia ʻana ma luna o ka ʻili micelle: E hoʻopili ʻia nā mea macromolecular, nā dyes, a me nā mea ʻē aʻe, ma luna o ka ʻili micelle a hoʻopaʻa ʻia ma o nā ikaika intermolecular van der Waals a i ʻole nā paʻa hydrogen, a laila e hoʻonui ai i ko lākou solubility i ka wai. Eia nō naʻe, ʻo ka nui o ka solubilization e kēia ʻano hana he liʻiliʻi iki.
④Ka hoʻoheheʻe ʻana ma waena o nā kaulahao polyoxyethylene: No nā surfactants ʻano polyoxyethylene, ma muli o ke kaulahao molekala lōʻihi o ko lākou ʻāpana hui hydrophilic, pinepine lākou i loko o kahi ʻano ʻōwili. Hiki ke ʻōwili ʻia nā mea olaola i loko a hoʻopaʻa ʻia e nā kaulahao polyoxyethylene hydrophilic. Loaʻa i kēia ʻano hana kahi nui o ka hoʻoheheʻe ʻana.
Hoʻopili kēia mau ʻano hoʻoheheʻe ʻehā i ke kumumanaʻo o ka like e hoʻoheheʻe like, a ʻo ke kaʻina o ka nui o ka solubilization mai ka nui a i ka liʻiliʻi: solubilization ma waena o nā kaulahao polyoxyethylene > solubilization i loko o ka papa micelle palisade > solubilization i loko o ka micelle > solubilization ma ka ʻili micelle.
He mea kūpono ke hoʻomaopopo ʻana ʻoiai ke piʻi nei ka solubility o nā mea olaola i loko o ka wai ma muli o ka solubilization, ʻaʻole loli nui nā ʻano o ka hopena. ʻO kēia no ka mea hiki i nā molekala olaola ke hana i nā ʻāpana nui, ʻaʻole e hopena i ka hoʻonui nui ʻana o ka nui o nā ʻāpana i loko o ka hopena. Hōʻike pololei kēia i ka hopena hoʻopaʻa a me ka hui pū ʻana o nā micelles ma kahi nui o nā molekala olaola.
2. Nā kumu e pili ana i ka hoʻoheheʻe ʻia
ʻAʻole pili wale ka hoʻoheheʻe ʻana i ke alo o nā micelles akā ua hoʻopilikia ʻia hoʻi e nā waiwai kūlohelohe o ka mea hoʻoheheʻe a me ka mea hoʻoheheʻe ʻia. Eia kekahi, ʻo kekahi mea e hiki ke hoʻopilikia i ka CMC o nā surfactants e hoʻopilikia pū i ka hoʻoheheʻe ʻana.
Mea hoʻoheheʻe (surfactant)
Ka nui o ka hui ʻana: ʻO ke kiʻekiʻe o ka nui o ka surfactant, ʻo ka nui o nā micelles i hana ʻia a ʻo ke kiʻekiʻe o ka hui ʻana o nā micelles, e hiki ai iā lākou ke launa pū me nā solubilizates hou aʻe.
ʻAno molekala: ʻO ka lōʻihi o ke kaulahao hydrocarbon hydrophobic, ʻoi aku ka ikaika o ka hopena solubilizing; no nā surfactants me ka hui hydrophilic like, ʻoi aku ka lōʻihi o ke kaulahao hydrocarbon hydrophobic, ʻoi aku ka liʻiliʻi o kā lākou CMC a ʻoi aku ka ikaika o ka hopena solubilizing. Eia kekahi, ʻoi aku ka ikaika o ka hopena solubilizing o nā surfactants non-ionic ma mua o nā surfactants ionic.
Hoʻoheheʻe ʻia
Ma keʻano laulā, ʻo ka nui o ka polarity o ka mea i hoʻoheheʻe ʻia, ʻo ka nui o ka hiki ke hoʻoheheʻe ʻia. ʻO kēia paha no ka mea ʻoi aku ka nui o nā mea i hoʻoheheʻe ʻia i ka polar e launa pū me nā hui hydrophilic ma ka ʻili o nā micelles ma o nā pilina hydrogen a me nā mana van der Waals. I ka manawa like, ʻo kā lākou mau ʻāpana non-polar e launa pū me nā hui hydrophobic o nā surfactants.
Mahana
No nā surfactants ionic, ʻo ka hoʻonui ʻana o ka mahana e hoʻonui i kā lākou hopena solubilization. ʻO kēia no ka mea ʻo ka piʻi ʻana o ka mahana e hoʻonui i ka CMC, e ʻae ana i nā surfactants hou aʻe e hoʻoheheʻe i loko o ka hopena a hana i nā micelles hou aʻe.
No nā surfactants nonionic ʻano polyoxyethylene, piʻi pū ka hiki ke hoʻoheheʻe ʻia me ka piʻi ʻana o ka mahana. Eia nō naʻe, ke hiki a ʻoi aku paha ka mahana i ke kiko ao, e nāwaliwali ka hopena hoʻoheheʻe ʻia.
ʻElektrolita
Hiki i ka hoʻohui ʻana i nā electrolytes ke hoʻonui i ka hiki ke hoʻoheheʻe ʻia o nā surfactants ionic no nā hydrocarbons akā e hōʻemi i ko lākou hiki ke hoʻoheheʻe ʻia no nā mea polar. ʻO kēia no ka mea hoʻopau nā electrolytes i kahi hapa o ka uku uila o nā hui hydrophilic, e hoʻolilo ana i ka hoʻonohonoho ʻana o nā hui hydrophilic ma ka ʻili micelle i ʻoi aku ka liʻiliʻi, kahi mea kūpono ʻole no ka hoʻokomo ʻana o nā solubilizates polar.
No nā surfactants non-ionic, hiki i ka hoʻohui ʻana i nā electrolytes ke hoʻonui i ko lākou hiki ke hoʻoheheʻe ʻia. ʻO kēia ma muli o ka hopena paʻakai, kahi e hōʻemi ai i ke kāohi ʻana o ka wai ma luna o nā mole surfactant, hoʻonui i ko lākou neʻe ʻana, a maʻalahi hoʻi i ka hana ʻana o nā micelles.
He hanana paʻakikī ka hoʻoheheʻe ʻia ʻana i hoʻopilikia ʻia e nā kumu like ʻole. Ma ka loaʻa ʻana o kahi ʻike hohonu o kēia mau mea a me kā lākou mau ʻano hana launa pū, hiki iā mākou ke hoʻohana maikaʻi i ka hoʻoheheʻe ʻia ʻana e hoʻomaikaʻi i nā kaʻina hana kemika a me ka hana huahana.
