Igama elihlanganisiwe le-hydroxyethyl cellulose

Igama elihlanganisiwe le-hydroxyethyl celtulose (HEC) libonisa ukwakheka kwalo kwamakhemikhali kanye nokuguqulwa okwenziwe ku-cellulose yemvelo. I-HEC iyi-ether ye-cellulose, okusho ukuthi isuselwa ku-cellulose ngenqubo yamakhemikhali eyaziwa ngokuthi ukusheshisa. Ngokukhethekile, amaqembu e-hydroxyethyl angeniswa emgogodleni we-cellulose.

I-IUPAC (I-International Union of Chemistry) Igama le-HydroxYethyl celtule lizosuselwa esakhiweni se-cellulose enamaqembu we-hydroxyethyl. Isakhiwo samakhemikhali se-cellulose yi-polysaccharide eyinkimbinkimbi eyakhiwa kabusha amayunithi we-glucose.

Isakhiwo samakhemikhali se-Hydroxyyethyl celtulese singavezwa njengoba:

Kulesi sethulo:

• Iyunithi ye- [-O-CH2-CH2] imele i-cellulose backbone.
• Amaqembu [-ch2-CH2] amele amaqembu e-hydroxyethyll athulwa ngokuthezeka.

Njengoba kunikezwe ubulukhuni besakhiwo se-cellulose kanye namasayithi athile we-hydroxyethylation, ukuhlinzeka ngegama le-IUPACTIC STIMCE LUPEC kungaba yinselele. Igama livame ukubhekisela ekuguqulweni okwenziwe ku-cellulose esikhundleni se-Iupac Menclature ethile.

Igama elisetshenziswa kaningi "Hydroxyyethyl cellulose" libonisa bobabili umthombo (iselula) kanye nokuguqulwa (amaqembu we-hydroxyethyl) ngendlela ecacile nechazayo.
