Ethyl cellulose solubility mu ethanol

Ethyl cellulose solubility mu ethanol

Ethyl cellulose ipolymer yekugadzira iyo inowanzoshandiswa mumaindasitiri akasiyana siyana, kusanganisira mishonga, chikafu, uye kutarisira wega. Chimwe chezvinhu zvakakosha zve ethyl cellulose kunyungudika kwayo mune zvakasiyana zvinonyungudutsa, izvo zvakakosha pakushandisa kwayo kwakasiyana. Ethanol chimwe chezvinonyungudutsa zvinogona kushandiswa kunyungudutsa ethyl cellulose.

Kunyungudika kwe ethyl cellulose mu ethanol kunoenderana nezvinhu zvakasiyana senge degree re ethylation, huremu hwema molecular epolymer, uye tembiricha yezvinonyungudutsa. Kazhinji, ethyl cellulose ine huwandu hwepamusoro hwe ethylation inonyanya kunyungudika mu ethanol kana ichienzaniswa neavo vane dhigirii yakaderera ye ethylation. Huremu hwepolymer huremu hunoitawo basa, sezvo mapolymer akakwira huremu angangoda kuwanda kwe ethanol kana nguva yakareba yekunyungudika.

Kupisa kweiyo solvent kunokanganisawo kunyungudika kwe ethyl cellulose mu ethanol. Tembiricha yepamusoro inogona kuwedzera kunyungudika kwepolymer nekuda kwekuwedzera kinetic simba remamorekuru anonyungudutsa, ayo anogona kubatsira kuputsa cheni dzepolymer uye kufambisa nzira yekunyungudutsa. Nekudaro, tembiricha haifanire kudarika imwe muganho nekuti inogona kukonzera iyo polymer kudzikisira kana kurasikirwa nehunhu hwayo.

Kazhinji, ethyl cellulose inoonekwa seinonyungudika mu ethanol kana ichienzaniswa nezvimwe zvinonyungudutsa zvakajairika semvura, methanol, uye acetone. Ethanol is polar solvent, uye polarity yayo inogona kubatsira kuputsa zvisungo zvehydrogen pakati pecheni dzepolymer, zvichibvumira iyo polymer kunyungudika.
