I-Selersese Ether

I-Seley Sether Itery (i-seluplose ithe) yenziwa kwi-sellulose kwi-etheride yokuphendula ye-etherisition ye-etherhesition ye-EARESS enye okanye i-EARESS ye-EEURE kunye nokugaya okukodwa. Ngokutsho kwezakhiwo ezahlukeneyo zekhemikhali ze-ether ethengisa izinto, i-seluplose edade zinokwahlulwa zibe zii-ANION, CIORIC kunye nooManu base-Anic kunye nooManu. I-Ionic seluplose ebhutsa kubandakanya i-carboxymethyl setherlose ether (CMC); I-ionic selsulose e-Ionic ye-Ioni ye-Inicrail ibandakanya i-methyl setelise ye-ether (MC), i-hydroxypropyl methyl setherulose ether (i-HPMC) kunye ne-hydroxyyethyl sethe. I-chlorine ether (HC) njalo njalo. I-Unic e-Ionic yahlulahlulwe yazibulala amanzi kunye nee-oni zeoyile, kunye nee-Ionic zamanzi anyibilikisiweyo ikakhulu zisetyenziswa kwiimveliso zodaka. Phambi kwe-calcium Ions, ionic seluplose ether ayizinzanga, ngoko ayifane isetyenziswe kwiimveliso ezixubileyo ezixubileyo ezisebenzisa isamente, i-lime yentsimbi, njl. I-Infoulose yamanzi anyibilikiswa amanzi asetyenziswa kakhulu kwishishini lezinto zokwakha ngenxa yokuzibandakanya nokugcinwa kwamanzi.

Iipropathi zekhemikhali ze-seluplose ether

I-ether nganye iseti inesiseko esisisiseko se-selellulose -ahydroglucose. Kwinkqubo yokuvelisa i-Ilupelose Ether, iFiseb se-selselose ishushu kwisisombululo se-alkaline, emva koko sanyangwa ngearhente yokuthetha. Imveliso yokuphendula ye-Fibral yokuphendula ihlanjululwe kwaye iphoselwe ukuba yenze umgubo weyunifomu kunye nokutyibilika.

Kwinkqubo yemveliso ye-MC, i-methyl chloride isetyenziswa njenge-arhente yokwamkelwa; Ukongeza kwi-methyl chloride, i-propylene oxide ikwasetyenziselwa ukufumana amaqela athabathekayo e-hydroxypropy kwimveliso ye-HPMC. Iiseli ezahlukeneyo ze-Seleculose enee-methyl ezahlukeneyo kunye ne-hydroxyproplowl ye-hydyl ye-hydropyl, echaphazela ubushushu be-organic gesic kunye neqondo lokuhlaselwa kwe-thermal yesisombululo se-seluplose.
