Magaca isku dhafan ee hydroxyethyl cellulose

Magaca isku dhafka ah ee Hydroxyethyl Cellulose (HEC) wuxuu ka tarjumayaa qaab dhismeedka kiimikada iyo wax ka beddelka lagu sameeyay cellulose dabiiciga ah.HEC waa ether cellulose, taasoo la micno ah in laga soo qaatay cellulose iyada oo loo marayo habka kiimikada loo yaqaan etherification.Gaar ahaan, kooxaha hydroxyethyl waxaa lagu soo bandhigaa laf dhabarta cellulose.

IUPAC (Ururka Caalamiga ah ee Pure and Applied Chemistry) magaca Hydroxyethyl Cellulose wuxuu ku salaysnaan doonaa qaab dhismeedka cellulose oo ay la socdaan kooxaha hydroxyethyl ee lagu daray.Qaab dhismeedka kiimikada ee cellulose waa polysaccharide adag oo ka kooban unugyo gulukoos oo soo noqnoqda.

Qaab dhismeedka kiimikaad ee Hydroxyethyl Cellulose waxa lagu matali karaa sida:

matalaaddan:

• Unugga [-O-CH2-CH2-O-] waxa ay u taagan yihiin laf dhabarta cellulose.
• Kooxaha [-CH2-CH2-OH] waxay matalaan kooxaha hydroxyethyl ee lagu soo bandhigay sifeynta.

Marka la eego kakanaanta qaabka cellulose-ka iyo goobaha gaarka ah ee hydroxyethylation, bixinta magaca IUPAC ee nidaamsan ee HEC waxay noqon kartaa mid adag.Magaca inta badan waxa uu tilmaamayaa wax ka beddelka lagu sameeyay cellulose halkii uu ka ahaan lahaa magacyo IUPAC gaar ah.

Magaca caadiga ah ee la isticmaalo "Hydroxyethyl Cellulose" wuxuu ka tarjumayaa labadaba isha (cellulose) iyo wax ka beddelka (kooxaha hydroxyethyl) si cad oo qeexan.
