Lebitso la motsoako oa hydroxyethyl cellulose

Lebitso la motsoako la Hydroxyethyl Cellulose (HEC) le bonts'a sebopeho sa eona sa lik'hemik'hale le liphetoho tse entsoeng ho cellulose ea tlhaho. HEC ke ether ea cellulose, ho bolelang hore e nkiloe ho cellulose ka ts'ebetso ea lik'hemik'hale e tsejoang e le etherification. Ka ho khetheha, lihlopha tsa hydroxyethyl li kenngoa mokokotlong oa cellulose.

Lebitso la IUPAC (Mokhatlo oa Machaba oa K'hemistri e Hloekileng le e Sebelisitsoeng) bakeng sa Hydroxyethyl Cellulose le tla ipapisa le sebopeho sa cellulose ka lihlopha tse ekelitsoeng tsa hydroxyethyl. Sebopeho sa lik'hemik'hale sa cellulose ke polysaccharide e rarahaneng e entsoeng ka li-unit tsa glucose tse pheta-phetoang.

Sebopeho sa lik'hemik'hale sa Hydroxyethyl Cellulose se ka emeloa tjena:

Moemeling ona:

• Yuniti ea [-O-CH2-CH2-O-] e emela mokokotlo oa cellulose.
• Lihlopha tsa [-CH2-CH2-OH] li emela lihlopha tsa hydroxyethyl tse hlahisitsoeng ka etherification.

Ka lebaka la ho rarahana ha sebopeho sa cellulose le libaka tse itseng tsa hydroxyethylation, ho fana ka lebitso le hlophisitsoeng la IUPAC bakeng sa HEC ho ka ba thata. Lebitso hangata le bolela phetoho e entsoeng ho cellulose ho fapana le lebitso le itseng la IUPAC.

Lebitso le sebelisoang hangata "Hydroxyethyl Cellulose" le bonts'a mohloli (cellulose) le phetoho (lihlopha tsa hydroxyethyl) ka mokhoa o hlakileng le o hlalosang.
