Igama elihlanganisiweyo le-hydroxyethyl cellulose

Igama elihlanganisiweyo le-Hydroxyethyl Cellulose (HEC) libonisa ubume bekhemikhali kunye nohlengahlengiso olwenziwe kwiselulosi yendalo. I-HEC yi-ether ye-cellulose, oku kuthetha ukuba iphuma kwi-cellulose ngokusebenzisa inkqubo yekhemikhali eyaziwa ngokuba yi-etherification. Ngokukodwa, amaqela e-hydroxyethyl angeniswa kwi-cellulose backbone.

I-IUPAC (iManyano yaMazwe ngaMazwe yeChemistry ePure kunye neApplied) yeHydroxyethyl Cellulose iya kusekelwa kulwakhiwo lweselulosi kunye namaqela adityanisiweyo e-hydroxyethyl. Ubume bemichiza ye-cellulose yi-polysaccharide eyinkimbinkimbi ehlanganiswe ngokuphindaphindiweyo kweeyunithi ze-glucose.

Ubume bekhemikhali yeHydroxyethyl Cellulose inokumelwa ngolu hlobo:

Kulo mboniso:

• Iyunithi ye- [-O-CH2-CH2-O-] imele i-cellulose backbone.
• Amaqela [-CH2-CH2-OH] amele amaqela e-hydroxyethyl aziswa nge-etherification.

Ukunikezelwa kobunzima besakhiwo se-cellulose kunye neendawo ezithile ze-hydroxyethylation, ukubonelela ngegama le-IUPAC elicwangcisiweyo le-HEC linokuba ngumngeni. Igama lihlala libhekisa kulungiso olwenziwe kwiselulosi endaweni ye-nomenclature ye-IUPAC ethile.

Igama elisetyenziswa ngokuqhelekileyo elithi "Hydroxyethyl Cellulose" libonisa zombini umthombo (cellulose) kunye nokuguqulwa (amaqela e-hydroxyethyl) ngendlela ecacileyo nechazayo.
