Danani dzina la hydroxyethyl cellulose

Dzinalo la ma hydroxyethyl cellulose (hec) limawonetsa kapangidwe kake ndikusintha kwa cellulose yachilengedwe. Hec ndi ether ether, kutanthauza kuti zimachokera ku cellulose kudzera mu mankhwala omwe amadziwika kuti ndi kusinthana. Makamaka, magulu a hydroxyethyl amayambitsidwa pa foni yam'manja ya cellulose.

The Iupac (mgwirizano wapadziko lonse wa machesi oyera) dzina la machesi a hydrothyl cellulose omwe angakhazikitsidwe ndi ma cellulose omwe ali ndi magulu a hydroxyethyl. Kapangidwe ka mankhwala kwa cellulose ndi polysardide yovuta yopangidwa kuti abwerere mayunitsi a shuga.

Kapangidwe ka mankhwala hydrothyl cellulose kumatha kuyimitsidwa monga:

Mu choyimira ichi:

• The [-CH2 CH2-CH2]
• Magulu a [-ch2-oh] akuimira magulu a hydrothyl omwe amakhazikitsidwa chifukwa cha kukonzekera.

Popeza mitundu yovuta ya kapangidwe ka mureulse ndi masamba a hydroxetylation, kupereka dzina la IUTAC kungakhale kovuta. Dzinali limatanthauzira kusintha komwe kunachitika kwa cellulose m'malo mwa ipaulclation.

Dzina lomwe limagwiritsidwa ntchito "hydroxethyl cellulose" limawonetsa gwero (cellulose) ndi kusinthana (magulu a hydroxyethyl) momveka bwino.
