Compound lub npe ntawm hydroxyethyl cellulose

Cov npe sib xyaw ntawm hydroxyethyl cellulose (HEC) xav txog nws cov qauv tshuaj thiab cov hloov kho tau rau cov cellulose ntuj. HEC yog lub cellulose ether, lub ntsiab lus nws yog muab los ntawm cellulose los ntawm cov txheej txheem tshuaj hu ua etherification. Tshwj xeeb, hydroxyethyl pab pawg tau qhia rau lub cellulose caj qaum.

Qhov IUPAC (International Union ntawm cov tshuaj dawb thiab siv chemtry) lub npe rau cov qauv ntawm cov qauv ntawm cov qauv hydroxyethyl pawg. Cov qauv tshuaj ntawm cov cellulose yog cov polysaccharide tsim los ntawm cov chav dej qab zib kom rov qab ua.

Cov qauv siv tshuaj ntawm hydroxyethyl cellulose tuaj yeem sawv cev raws li:

Hauv cov sawv cev no:

• Chav tsev [-O-CH2-O-O] sawv cev rau lub cellulose caj qaum.
• [-Ch2-ch2-oh] pab pawg sawv cev rau cov pab pawg hydroxyethyl qhia los ntawm etherification.

Muab qhov nyuaj ntawm lub cellulose qauv thiab cov chaw tshwj xeeb ntawm hydroxyethylation, muab lub npe iupac systematic rau HEC tuaj yeem nyuaj. Lub npe feem ntau yog hais txog kev hloov kho tau ua rau cellulose ntau dua li qhov tshwj xeeb Iupenclature.

Lub npe siv uas nquag siv "Hydroxyethyl cellulose" tsom ob qho ntawm cov hauv paus (cellulose) thiab kev hloov kho (hydrotethyl pawg) thiab piav qhia.
