Orukọ apapọ ti hydroxyethyl cellulose

Orukọ agbopọ ti Hydroxyethyl Cellulose (HEC) ṣe afihan ọna kemikali rẹ ati awọn iyipada ti a ṣe si cellulose adayeba. HEC jẹ ether cellulose, afipamo pe o ti wa lati cellulose nipasẹ ilana kemikali ti a mọ ni etherification. Ni pato, awọn ẹgbẹ hydroxyethyl ni a ṣe afihan si ẹhin cellulose.

Orukọ IUPAC (International Union of Pure and Applied Chemistry) fun Hydroxyethyl Cellulose yoo da lori eto cellulose pẹlu awọn ẹgbẹ hydroxyethyl ti a ṣafikun. Eto kemikali ti cellulose jẹ polysaccharide eka kan ti o jẹ ti awọn iwọn glukosi atunwi.

Ilana kemikali ti Hydroxyethyl Cellulose le jẹ aṣoju bi:

Ninu aṣoju yii:

• Ẹka [-O-CH2-CH2-O-] duro fun ẹhin cellulose.
• Awọn ẹgbẹ [-CH2-CH2-OH] ṣe aṣoju awọn ẹgbẹ hydroxyethyl ti a ṣe nipasẹ etherification.

Fi fun idiju ti eto cellulose ati awọn aaye kan pato ti hydroxyethylation, pese orukọ IUPAC eto kan fun HEC le jẹ nija. Orukọ nigbagbogbo n tọka si iyipada ti a ṣe si cellulose kuku ju nomenclature IUPAC kan pato.

Orukọ ti a nlo nigbagbogbo “Hydroxyethyl Cellulose” ṣe afihan orisun mejeeji (cellulose) ati iyipada (awọn ẹgbẹ hydroxyethyl) ni ọna ti o han gbangba ati asọye.
