Igama elihlanganisiwe le-hydroxyethyl cellulose

Igama elihlanganisiwe le-Hydroxyethyl Cellulose (HEC) libonisa ukwakheka kwamakhemikhali ayo kanye nokuguqulwa okwenziwe ku-cellulose yemvelo.I-HEC iyi-ether ye-cellulose, okusho ukuthi itholakala ku-cellulose ngenqubo yamakhemikhali eyaziwa ngokuthi i-etherification.Ngokuqondile, amaqembu e-hydroxyethyl angeniswa 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 iyi-polysaccharide eyinkimbinkimbi eyakhiwe amayunithi aphindaphindayo e-glucose.

Isakhiwo samakhemikhali se-Hydroxyethyl Cellulose singamelwa kanje:

Kulesi sethulo:

• Iyunithi ye-[-O-CH2-CH2-O-] imele umgogodla we-cellulose.
• Amaqembu e-[-CH2-CH2-OH] amele amaqembu e-hydroxyethyl ethulwe nge-etherification.

Uma kubhekwa inkimbinkimbi yesakhiwo se-cellulose kanye nezindawo ezithile ze-hydroxyethylation, ukunikeza igama le-IUPAC elihlelekile le-HEC kungaba inselele.Igama livamise ukusho ukuguqulwa okwenziwe ku-cellulose esikhundleni segama elithile le-IUPAC.

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