Hydroxyethyl cellulose ether

Hydroxyethyl cellulose ether ne wanda ba ionic ruwa-soluble polymer, mai narkewa a cikin ruwan zafi da sanyi.Hydroxyethyl cellulose ether yana da nau'i-nau'i iri-iri na danko, kuma duk mafita na ruwa ba Newtonian ba ne.

Hydroxyethyl cellulose ether yana da kyawawan kaddarorin hydration.Maganin ruwan sa mai santsi ne kuma iri ɗaya, tare da ruwa mai kyau da daidaitawa

Mai zuwa shine madaidaicin tsarin tsarin kwayoyin halitta na hydroxyethyl cellulose ether:

N = digiri na tarawa

Akwai rukunin hydroxyl guda uku akan kowace naúrar anhydroglucose a cikin cellulose, wanda aka bi da shi tare da alkali a cikin maganin sodium hydroxide mai ruwa don samun gishirin sodium na cellulose, sannan a sami amsawar etherification tare da ethylene oxide don samar da hydroxyethyl cellulose ether.A cikin aiwatar da haɗakar HEC, ethylene oxide ba zai iya maye gurbin ƙungiyoyin hydroxyl kawai akan cellulose ba, amma kuma yana jure yanayin sarkar polymerization tare da ƙungiyoyin hydroxyl a cikin ƙungiyoyin da aka maye gurbinsu.
