Dzina lophatikizana la hydroxyethyl cellulose

Dzina lophatikizika la Hydroxyethyl Cellulose (HEC) limawonetsa kapangidwe kake kamankhwala komanso kusintha komwe kumapangidwa ku cellulose yachilengedwe. HEC ndi cellulose ether, kutanthauza kuti imachokera ku cellulose kudzera mu njira yamankhwala yotchedwa etherification. Makamaka, magulu a hydroxyethyl amalowetsedwa pamsana wa cellulose.

Dzina la IUPAC (International Union of Pure and Applied Chemistry) la Hydroxyethyl Cellulose likatengera kapangidwe ka cellulose ndi magulu owonjezera a hydroxyethyl. Kapangidwe kake ka cellulose ndi polysaccharide yopangidwa ndi mayunitsi obwerezabwereza a glucose.

Kapangidwe kake ka Hydroxyethyl Cellulose kumatha kuyimiridwa motere:

Pachithunzichi:

• Chigawo cha [-O-CH2-CH2-O-] chimayimira msana wa cellulose.
• Magulu a [-CH2-CH2-OH] amaimira magulu a hydroxyethyl oyambitsidwa kudzera mu etherification.

Poganizira zovuta zamapangidwe a cellulose ndi malo enieni a hydroxyethylation, kupereka mwadongosolo dzina la IUPAC la HEC kungakhale kovuta. Dzinali nthawi zambiri limatanthauza kusinthidwa kwa cellulose m'malo mwa dzina la IUPAC.

Dzina lomwe limagwiritsidwa ntchito kwambiri "Hydroxyethyl Cellulose" limawonetsa gwero (ma cellulose) ndikusintha (magulu a hydroxyethyl) momveka bwino komanso mofotokozera.
