Aha ngwakọta nke hydroxyethyl cellulose

Aha ngwakọta nke Hydroxyethyl Cellulose (HEC) na-egosipụta usoro kemịkalụ ya na mgbanwe ndị emere na cellulose eke. HEC bụ cellulose ether, nke pụtara na ọ sitere na cellulose site na usoro kemịkal a maara dị ka etherification. Kpọmkwem, a na-ewebata otu hydroxyethyl n'ime ọkpụkpụ azụ cellulose.

Aha IUPAC (International Union of Pure and Applied Chemistry) maka Hydroxyethyl Cellulose ga-adabere na nhazi nke cellulose yana otu hydroxyethyl agbakwunyere. Ọdịdị kemịkalụ nke cellulose bụ polysaccharide dị mgbagwoju anya nke mejupụtara nkeji glucose ugboro ugboro.

Enwere ike ịnọchite anya usoro kemịkalụ nke Hydroxyethyl Cellulose dị ka:

Na nnọchite a:

• Ngalaba [-O-CH2-CH2-O-] na-anọchi anya ọkpụkpụ azụ cellulose.
• Otu [-CH2-CH2-OH] na-anọchi anya otu hydroxyethyl ewepụtara site na etherification.

Nyere mgbagwoju anya nke usoro cellulose na saịtị ndị a kapịrị ọnụ nke hydroxyethylation, inye aha IUPAC ahaziri maka HEC nwere ike bụrụ ihe ịma aka. Aha a na-ezokarị aka na mgbanwe emere na cellulose karịa aha aha IUPAC.

Aha a na-akpọkarị "Hydroxyethyl Cellulose" na-egosipụta ma isi mmalite (cellulose) na mgbanwe (hydroxyethyl otu) n'ụzọ doro anya na nkọwa.
