Tsarin sinadaran cellulose ether abubuwan da aka samo

Cellulose ethers sune abubuwan da aka samo daga cellulose, polysaccharide na halitta da ake samu a cikin ganuwar tantanin halitta. Tsarin sinadarai na ethers cellulose yana da alaƙa da gabatarwar ƙungiyoyin ether daban-daban ta hanyar gyare-gyaren sinadarai na ƙungiyoyin hydroxyl (-OH) da ke cikin kwayoyin cellulose. Mafi yawan nau'ikan ethers cellulose sun haɗa da:

1. Hydroxypropyl Methylcellulose (HPMC):
   • Tsarin:
     • An haɗa HPMC ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose tare da ƙungiyoyin hydroxypropyl (-OCH2CHOHCH3) da methyl (-OCH3).
     • Matsayin maye gurbin (DS) yana nuna matsakaicin adadin rukunin hydroxyl da aka maye gurbinsu da rukunin glucose a cikin sarkar cellulose.
2. Carboxymethyl cellulose(CMC):
   • Tsarin:
     • An samar da CMC ta hanyar gabatar da ƙungiyoyin carboxymethyl (-CH2COOH) zuwa ƙungiyoyin hydroxyl na cellulose.
     • Ƙungiyoyin carboxymethyl suna ba da solubility na ruwa da halayen anionic zuwa sarkar cellulose.
3. Hydroxyethyl Cellulose (HEC):
   • Tsarin:
     • Ana samun HEC ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose tare da ƙungiyoyin hydroxyethyl (-OCH2CH2OH).
     • Yana nuna ingantaccen narkewar ruwa da kaddarorin kauri.
4. Methyl Cellulose (MC):
   • Tsarin:
     • Ana samar da MC ta hanyar gabatar da ƙungiyoyin methyl (-OCH3) zuwa ƙungiyoyin hydroxyl na cellulose.
     • An fi amfani da shi don riƙewar ruwa da kayan aikin fim.
5. Ethyl Cellulose (EC):
   • Tsarin:
     • An haɗa EC ta hanyar maye gurbin ƙungiyoyin hydroxyl na cellulose tare da ƙungiyoyin ethyl (-OC2H5).
     • An san shi don rashin narkewa a cikin ruwa kuma ana amfani dashi sau da yawa wajen samar da sutura da fina-finai.
6. Hydroxypropyl Cellulose (HPC):
   • Tsarin:
     • Ana samun HPC ta hanyar gabatar da ƙungiyoyin hydroxypropyl (-OCH2CHOHCH3) zuwa ƙungiyoyin hydroxyl na cellulose.
     • Ana amfani da shi azaman ɗaure, tsohon fim, da mai gyara danko.

Ƙayyadadden tsari ya bambanta ga kowane nau'in ether cellulose bisa ga nau'i da digiri na maye gurbin da aka gabatar yayin aikin gyaran sinadaran. Gabatar da waɗannan ƙungiyoyin ether suna ba da takamaiman kaddarorin ga kowane ether cellulose, yana sa su dace da aikace-aikacen masana'antu daban-daban.
