Hydroxyethylcellulose(HEC) wani nau'in polymer ne mai mahimmanci wanda ke samo aikace-aikace masu fadi a cikin masana'antu daban-daban saboda musamman kaddarorinsa. An samo shi daga cellulose, daya daga cikin mafi yawan nau'in polymers na halitta, HEC ya ba da hankali sosai ga ruwa-ruwa, yanayin da ba na ionic ba, da ikon samar da mafita na viscoelastic. Wannan cikakken jagorar yana bincika tsari, kaddarorin, kira, aikace-aikace, da yuwuwar ci gaban hydroxyethylcellulose na gaba.

Tsarin da Kaddarorin Hydroxyethylcellulose:

HEC wani abin da aka samu na cellulose, polysaccharide mai layi wanda ya ƙunshi raka'o'in glucose mai maimaitawa wanda aka haɗa ta β (1 → 4) glycosidic bonds. Ƙungiyoyin hydroxyl (-OH) tare da kashin baya na cellulose suna samar da wurare don gyare-gyaren sinadarai, wanda ke haifar da ƙirƙirar nau'o'in cellulose daban-daban kamar HEC. A cikin yanayin HEC, ƙungiyoyin hydroxyethyl (-CH2CH2OH) an gabatar da su akan kashin bayan cellulose ta hanyar halayen etherification.

Matsayin maye gurbin (DS), wanda ke nufin matsakaicin adadin ƙungiyoyin hydroxyethyl a kowace rukunin anhydroglucose, yana rinjayar kaddarorin HEC.
