Magaca isku-dhafka ah ee cellulose-ka hydroxyethyl

Magaca isku-dhafka ah ee Hydroxyethyl Cellulose (HEC) wuxuu ka tarjumayaa qaab-dhismeedkiisa kiimikada iyo wax-ka-beddelka lagu sameeyay cellulose-ka dabiiciga ah. HEC waa cellulose ether, taasoo la macno ah inay ka soo baxdo cellulose iyada oo loo marayo hab kiimiko ah oo loo yaqaan etherification. Gaar ahaan, kooxaha hydroxyethyl waxaa lagu soo bandhigaa laf-dhabarta cellulose.

Magaca IUPAC (Ururka Caalamiga ah ee Kiimikada Saafiga ah iyo La Adeegsaday) ee Hydroxyethyl Cellulose wuxuu ku salaysnaan doonaa qaab-dhismeedka cellulose oo ay weheliyaan kooxaha hydroxyethyl ee lagu daray. Qaab-dhismeedka kiimikada ee cellulose waa polysaccharide isku dhafan oo ka kooban cutubyo gulukoos oo soo noqnoqda.

Qaab-dhismeedka kiimikada ee Hydroxyethyl Cellulose waxaa lagu matali karaa sida soo socota:

Matalaaddan:

• Cutubka [-O-CH2-CH2-O-] wuxuu matalaa laf-dhabarta cellulose-ka.
• Kooxaha [-CH2-CH2-OH] waxay matalaan kooxaha hydroxyethyl ee lagu soo bandhigay etherification.

Marka la eego kakanaanta qaab-dhismeedka cellulose iyo goobaha gaarka ah ee hydroxyethylation, bixinta magaca IUPAC ee nidaamsan ee HEC waxay noqon kartaa mid adag. Magacu wuxuu inta badan tilmaamayaa wax ka beddelka lagu sameeyay cellulose halkii laga isticmaali lahaa magac gaar ah oo IUPAC ah.

Magaca caadiga ah ee loo yaqaan "Hydroxyethyl Cellulose" wuxuu ka tarjumayaa isha (cellulose) iyo wax-ka-beddelka (kooxaha hydroxyethyl) labadaba si cad oo sharraxaad leh.
