Dzina la hydroxyethyl cellulose

Dzina la Hydroxyethyl Cellulose (HEC) limasonyeza kapangidwe kake ka mankhwala ndi kusintha komwe kumachitika ku cellulose yachilengedwe. HEC ndi cellulose ether, zomwe zikutanthauza kuti imachokera ku cellulose kudzera mu njira ya mankhwala yotchedwa etherification. Makamaka, magulu a hydroxyethyl amalowetsedwa pa msana wa cellulose.

Dzina la IUPAC (International Union of Pure and Applied Chemistry) la Hydroxyethyl Cellulose limachokera ku kapangidwe ka cellulose ndi magulu owonjezera a hydroxyethyl. Kapangidwe ka mankhwala a cellulose ndi polysaccharide yovuta yopangidwa ndi mayunitsi obwerezabwereza a shuga.

Kapangidwe ka mankhwala a Hydroxyethyl Cellulose kakhoza kuimiridwa motere:

Mu chiwonetsero ichi:

• Chigawo cha [-O-CH2-CH2-O-] chikuyimira msana wa cellulose.
• Magulu a [-CH2-CH2-OH] akuyimira magulu a hydroxyethyl omwe amayambitsidwa kudzera mu etherification.

Popeza kapangidwe ka cellulose ndi kovuta komanso malo enieni a hydroxyethylation, kupereka dzina la IUPAC lokhazikika la HEC kungakhale kovuta. Dzinali nthawi zambiri limatanthauza kusintha komwe kunachitika ku cellulose m'malo mwa dzina la IUPAC.

Dzina lodziwika bwino lakuti "Hydroxyethyl Cellulose" limasonyeza gwero (cellulose) ndi kusintha (magulu a hydroxyethyl) momveka bwino komanso momveka bwino.
