I-Hydroxyethyl Cellulose Etere

I-Hydroxyethyl cellulose ether yipolymer engeyiyo-ionic emanzini, enyibilika kumanzi ashushu nabandayo.I-Hydroxyethyl cellulose ether inoluhlu olubanzi lwe-viscosities, kwaye zonke izisombululo zamanzi azikho i-Newtonian.

IHydroxyethyl cellulose ether ineepropathi ezilungileyo kakhulu zokugalela amanzi.Isisombululo saso esinamanzi sigudileyo kwaye siyafana, sinolwelo oluhle kunye nomgangatho

Oku kulandelayo yeyona fomyula ifanelekileyo yemolekyuli ye-hydroxyethyl cellulose ether:

N = iqondo lokuhlanganisa

Kukho amaqela amathathu e-hydroxyl kwiyunithi nganye ye-anhydroglucose kwi-cellulose, ephathwa nge-alkali kwisisombululo se-aqueous sodium hydroxide ukufumana ityuwa ye-cellulose yesodium, kwaye emva koko i-etherification reaction kunye ne-ethylene oxide ukwenza i-hydroxyethyl cellulose ether.Kwinkqubo yokutshintsha i-hec, i-ithoylene oxide ayinakukwazi ukuyifaka kuphela amaqela e-hydroxyl kwi-sellulose, kodwa ne-chain ye-polymerization i-chanmerization i-chancermerization iphindaphindwe ngamaqela e-hydroxyl kumaqela aphantsi.
