Ethyl cellulose solubility i ka acetone

ʻO ka Ethyl cellulose kahi polymer i hoʻohana nui ʻia i nā ʻoihana like ʻole, me ka lāʻau lapaʻau, ka meaʻai, a me ka mālama pilikino. Ua ʻike ʻia no kāna mau ʻano hana kiʻiʻoniʻoni maikaʻi loa, kūpono kiʻekiʻe me nā mea ʻē aʻe, a me ke kūpaʻa maikaʻi ʻana i nā mea kemika a me nā mea kūlohelohe. ʻO kekahi o nā waiwai koʻikoʻi o ka ethyl cellulose ʻo ia kona solubility, hiki ke ʻokoʻa ma muli o ka solvent i hoʻohana ʻia.

ʻO ka Acetone kahi mea hoʻoheheʻe maʻamau i hoʻohana pinepine ʻia i ka hana ʻana i nā kiʻiʻoniʻoni ethyl cellulose a me nā uhi. Hiki ke hoʻoheheʻe ʻia ka Ethyl cellulose i ka acetone, ʻo ia hoʻi hiki ke hoʻoheheʻe ʻia i kekahi ʻano akā ʻaʻole hiki ke hoʻoheheʻe piha. ʻO ke kiʻekiʻe o ka solubility o ka ethyl cellulose i ka acetone e pili ana i nā ʻano like ʻole e like me ke kaumaha molecular, degere o ka ethoxylation, a me ka neʻe ʻana o ka polymer.

Ma keʻano laulā, ʻoi aku ka liʻiliʻi o ka ethyl cellulose kiʻekiʻe o ke kaumaha molekala i ka acetone i hoʻohālikelike ʻia me ka ethyl cellulose haʻahaʻa. ʻO kēia no ka mea ʻoi aku ka kiʻekiʻe o ka polymer kaumaha molekala kiʻekiʻe o ka polymerization, ka hopena i kahi ʻano paʻakikī a paʻa paʻa i ʻoi aku ke kūpaʻa i ka solvation. Pēlā nō, ʻoi aku ka liʻiliʻi o ka ethyl cellulose me kahi kiʻekiʻe o ka ethoxylation i ka acetone ma muli o ka nui o ka hydrophobicity o ka polymer.

Hiki ke hoʻopili ʻia ka solubility o ka ethyl cellulose i ka acetone e ka ʻike ʻana o ka polymer i ka solvent. Ma nā haʻahaʻa haʻahaʻa, hiki ke hoʻoheheʻe ʻia ka ethyl cellulose i loko o ka acetone, ʻoiai ma nā kiʻekiʻe kiʻekiʻe, hiki ke emi ka solubility. ʻO kēia ma muli o ka ʻike ʻana ma nā ʻano kiʻekiʻe, ʻoi aku ka nui o nā molekala ethyl cellulose e launa pū kekahi me kekahi, e hana ana i kahi pūnaewele o nā kaulahao polymer i emi ʻole i ka solvent.

Hiki ke hoʻonui ʻia ka solubility o ka ethyl cellulose i ka acetone e ka hoʻohui ʻana o nā mea hoʻonā a i ʻole nā ​​​​plasticizers. No ka laʻana, hiki i ka hoʻohui ʻana o ka ethanol a i ʻole isopropanol i ka acetone ke hoʻonui i ka solubility o ka ethyl cellulose ma ka hoʻopau ʻana i nā pilina intermolecular ma waena o nā kaulahao polymer. Pēlā nō, hiki i ka hoʻohui ʻana o nā plasticizers e like me triethyl citrate a i ʻole dibutyl phthalate ke hoʻonui i ka solubility o ka ethyl cellulose ma ka hoʻemi ʻana i nā ikaika intermolecular ma waena o nā kaulahao polymer.

I ka hōʻuluʻulu ʻana, hiki ke hoʻoheheʻe ʻia ka ethyl cellulose i ka acetone, a hiki ke hoʻololi i kona solubility ma muli o nā ʻano like ʻole e like me ke kaumaha molekala, degere o ka ethoxylation, a me ka neʻe ʻana o ka polymer. Hiki ke hoʻonui ʻia ka solubility o ka ethyl cellulose i ka acetone e ka hoʻohui ʻana o nā mea hoʻoheheʻe ʻē aʻe a i ʻole plasticizers, e lilo ia i polymer versatile no ka hoʻohana ʻana i nā noi like ʻole.
