Tsarin sinadarai na abubuwan da aka samo daga cellulose ether

Kwayoyin Cellulose ethers an samo su ne daga cellulose, wani polysaccharide na halitta da ake samu a bangon tantanin halitta na tsirrai. Tsarin sinadarai na cellulose ethers yana da alaƙa da gabatar da ƙungiyoyin ether daban-daban ta hanyar gyaran sinadarai na ƙungiyoyin hydroxyl (-OH) da ke cikin ƙwayar cellulose. Mafi yawan nau'ikan ƙwayoyin cellulose ethers sun haɗa da:

1. Hydroxypropyl Methylcellulose (HPMC):
   • Tsarin:
     • Ana haɗa HPMC ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose da ƙungiyoyin hydroxypropyl (-OCH2CHOHCH3) da methyl (-OCH3).
     • Matsayin maye gurbin (DS) yana nuna matsakaicin adadin ƙungiyoyin hydroxyl da aka maye gurbinsu a kowace naúrar glucose a cikin sarkar cellulose.
2. Carboxymethyl cellulose(CMC):
   • Tsarin:
     • Ana samar da CMC ta hanyar shigar da ƙungiyoyin carboxymethyl (-CH2COOH) zuwa ga ƙungiyoyin hydroxyl na cellulose.
     • Rukunin carboxymethyl suna ba da ruwa da kuma yanayin anionic ga sarkar cellulose.
3. Haidroxyethyl Cellulose (HEC):
   • Tsarin:
     • Ana samun HEC ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose da ƙungiyoyin hydroxyethyl (-OCH2CH2OH).
     • Yana nuna ingantaccen narkewar ruwa da kuma kauri.
4. Methyl Cellulose (MC):
   • Tsarin:
     • Ana samar da MC ta hanyar gabatar da rukunin methyl (-OCH3) zuwa ga rukunin hydroxyl na cellulose.
     • Ana amfani da shi sosai don riƙe ruwa da kuma samar da fim.
5. Ethyl Cellulose (EC):
   • Tsarin:
     • Ana haɗa EC ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose da ƙungiyoyin ethyl (-OC2H5).
     • An san shi da rashin narkewar sa a cikin ruwa kuma ana amfani da shi sau da yawa wajen samar da rufi da fina-finai.
6. Cellulose na Hydroxypropyl (HPC):
   • Tsarin:
     • Ana samun HPC ta hanyar gabatar da rukunin hydroxypropyl (-OCH2CHOHCH3) zuwa ga rukunin hydroxyl na cellulose.
     • Ana amfani da shi azaman mai ɗaurewa, mai ɗaukar fim, da kuma mai canza danko.

Tsarin takamaiman ya bambanta ga kowane nau'in cellulose ether wanda aka samo asali bisa ga nau'in da matakin maye gurbin da aka gabatar yayin tsarin gyaran sinadarai. Gabatar da waɗannan ƙungiyoyin ether yana ba da takamaiman halaye ga kowane cellulose ether, wanda hakan ya sa suka dace da aikace-aikacen masana'antu daban-daban.
