Lebitso la motsoako oa hydroxyethyl cellulose

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

Lebitso la IUPAC (International Union of Pure and Applied Chemistry) bakeng sa Hydroxyethyl Cellulose le tla ipapisa le sebopeho sa cellulose le lihlopha tse ekelitsoeng tsa hydroxyethyl. Sebopeho sa lik'hemik'hale tsa selulose ke polysaccharide e rarahaneng e entsoeng ka likarolo tse pheta-phetoang tsa tsoekere.

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

Kemelong ena:

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

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

Lebitso le atisang ho sebelisoa "Hydroxyethyl Cellulose" le bonahatsa bobeli mohloli (cellulose) le phetoho (lihlopha tsa hydroxyethyl) ka mokhoa o hlakileng le o hlalosang.
