Lub npe sib xyaw ntawm hydroxyethyl cellulose

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

Lub npe IUPAC (International Union of Pure and Applied Chemistry) rau Hydroxyethyl Cellulose yuav yog raws li cov qauv ntawm cellulose nrog cov pab pawg hydroxyethyl ntxiv. Cov qauv tshuaj ntawm cellulose yog ib qho polysaccharide nyuaj uas muaj cov chav glucose rov ua dua.

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

Hauv daim ntawv no:

• Chav [-O-CH2-CH2-O-] sawv cev rau lub cellulose backbone.
• Cov pawg [-CH2-CH2-OH] sawv cev rau cov pawg hydroxyethyl uas tau qhia los ntawm kev sib xyaw ua ke.

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

Lub npe siv feem ntau "Hydroxyethyl Cellulose" qhia txog ob qho tib si qhov chaw (cellulose) thiab kev hloov kho (hydroxyethyl pawg) hauv txoj kev meej thiab piav qhia.
