Ethyl cellulose solubility i loko o ka ethanol

ʻO ka Ethyl cellulose kahi polymer synthetic i hoʻohana mau ʻia i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, a me ka mālama pilikino. ʻO kekahi o nā waiwai koʻikoʻi o ka ethyl cellulose ʻo kona solubility i nā solvents like ʻole, he mea nui ia no kāna mau noi like ʻole. ʻO Ethanol kekahi o nā mea hoʻoheheʻe hiki ke hoʻohana ʻia e hoʻopau i ka ethyl cellulose.

ʻO ka solubility o ka ethyl cellulose i loko o ka ethanol e pili ana i nā ʻano like ʻole e like me ke degere o ka ethylation, ke kaumaha molekala o ka polymer, a me ka mahana o ka solvent. ʻO ka maʻamau, ʻoi aku ka maʻalahi o ka ethyl cellulose me kahi kiʻekiʻe o ka ethylation i ka ethanol i hoʻohālikelike ʻia me nā mea me ka degere haʻahaʻa o ka ethylation. ʻO ke kaumaha o ka molekala o ka polymer kekahi kuleana, no ka mea, e koi ana nā polymers kaumaha kiʻekiʻe i ka ʻoi aku ka nui o ka ethanol a i ʻole ka manawa lōʻihi e hemo ai.

Hoʻopili pū ka mahana o ka mea hoʻoheheʻe i ka solubility o ka ethyl cellulose i ka ethanol. Hiki i nā mahana kiʻekiʻe ke hoʻonui i ka solubility o ka polymer ma muli o ka piʻi ʻana o ka ikehu kinetic o nā molekole solvent, hiki ke kōkua i ka wāwahi ʻana i nā kaulahao polymer a hoʻomaʻamaʻa i ke kaʻina hoʻoheheʻe. Eia nō naʻe, ʻaʻole pono ka mahana ma mua o kekahi palena no ka mea hiki ke hoʻohaʻahaʻa a nalowale paha ka polymer i kona kūpaʻa.

Ma keʻano laulā, manaʻo ʻia ʻo ka ethyl cellulose e hoʻoheheʻe ʻia i ka ethanol i hoʻohālikelike ʻia me nā mea hoʻoheheʻe maʻamau e like me ka wai, methanol, a me ka acetone. He mea hoʻoheheʻe polar ka Ethanol, a hiki i kona polarity ke kōkua i ka wāwahi i nā paʻa hydrogen ma waena o nā kaulahao polymer, e ʻae ai i ka polymer e hemo.
