Igama elihlanganisiwe le-hydroxyethyl cellulose

Igama elihlanganisiwe le-Hydroxyethyl Cellulose (HEC) libonisa isakhiwo sayo samakhemikhali kanye nokuguqulwa okwenziwe ku-cellulose yemvelo. I-HEC iyi-cellulose ether, okusho ukuthi itholakala ku-cellulose ngenqubo yamakhemikhali eyaziwa ngokuthi i-etherification. Ngokukhethekile, amaqembu e-hydroxyethyl afakwa kumgogodla we-cellulose.

Igama le-IUPAC (International Union of Pure and Applied Chemistry) le-Hydroxyethyl Cellulose lizosuselwa esakhiweni se-cellulose namaqembu e-hydroxyethyl engeziwe. Isakhiwo samakhemikhali se-cellulose siyi-polysaccharide eyinkimbinkimbi eyakhiwe amayunithi e-glucose aphindaphindayo.

Isakhiwo samakhemikhali se-Hydroxyethyl Cellulose singamelwa kanje:

Kulesi sikhundla:

• Iyunithi [-O-CH2-CH2-O-] imelela umgogodla we-cellulose.
• Amaqembu [-CH2-CH2-OH] amelela amaqembu e-hydroxyethyl angeniswa nge-etherification.

Njengoba kunikezwe ubunzima besakhiwo se-cellulose kanye nezindawo ezithile ze-hydroxyethylation, ukunikeza igama le-IUPAC elihlelekile le-HEC kungaba yinselele. Igama livame ukubhekisela ekuguqulweni okwenziwe ku-cellulose kunegama elithile le-IUPAC.

Igama elivame ukusetshenziswa elithi “Hydroxyethyl Cellulose” libonisa kokubili umthombo (i-cellulose) kanye nokuguqulwa (amaqembu e-hydroxyethyl) ngendlela ecacile nechazayo.
