Lub npe ntawm hydroxyethyl cellulose

Lub npe sib xyaw ntawm Hydroxyethyl Cellulose (HEC) qhia txog nws cov qauv tshuaj thiab cov kev hloov kho ua rau ntuj cellulose.HEC yog cellulose ether, txhais tau tias nws yog muab los ntawm cellulose los ntawm cov txheej txheem tshuaj hu ua etherification.Tshwj xeeb, pawg hydroxyethyl tau nkag mus rau hauv cov pob txha cellulose.

Lub IUPAC (International Union of Pure and Applied Chemistry) lub npe rau Hydroxyethyl Cellulose yuav ua raws li cov qauv ntawm cellulose nrog cov pab pawg hydroxyethyl ntxiv.Cov qauv tshuaj ntawm cellulose yog ib qho nyuaj polysaccharide tsim los ntawm cov piam thaj rov qab.

Cov qauv tshuaj ntawm Hydroxyethyl Cellulose tuaj yeem sawv cev raws li:

Hauv qhov sawv cev no:

• [-O-CH2-CH2-O-] chav tsev sawv cev rau cov pob txha cellulose.
• Cov pab pawg [-CH2-CH2-OH] sawv cev rau pawg hydroxyethyl qhia los ntawm etherification.

Muab qhov nyuaj ntawm cov qauv cellulose thiab cov chaw tshwj xeeb ntawm hydroxyethylation, muab lub npe IUPAC systematic rau HEC tuaj yeem nyuaj.Lub npe feem ntau hais txog kev hloov kho rau cellulose es tsis yog ib qho tshwj xeeb IUPAC nomenclature.

Feem ntau siv lub npe "Hydroxyethyl Cellulose" qhia txog qhov chaw (cellulose) thiab kev hloov kho (hydroxyethyl pawg) kom meej thiab piav qhia.
