Tsarin sunadarai na sel ether

PRELLUOS ELESS sune abubuwan da aka samo selulake, an samo polysaccharide na halitta a cikin bangon tantanin tsire-tsire. Tsarin sunadarai na cellulose na Ethers ne ya ƙunshi gabatarwar kungiyoyi daban-daban ta hanyar gyara na Hydroxyl ɗin da ke cikin kwayoyin selulose. Mafi yawan nau'ikan celulose sun hada da:

1. Hydroxypyl methylcelos (hpmc):
   • Tsarin:
     • HPMC ya hade ta hanyar musanya gungun masu hydroxyl tare da hydroxypropyl biyu (-och2chohcropyl (-och2chohcropyl (-och2chohcropyl (-och2chohch3) da methyl (-Och3) ƙungiyoyi.
     • Matsayi na musanya (DS) yana nuna matsakaicin adadin rukunin Hydroxyl a kowace ɓangaren glucose a cikin sarkar sel.
2. CarBoxymose Carboxymethyl(CMC):
   • Tsarin:
     • Ana samar da CRC ta hanyar gabatar da ƙungiyoyi na Carboxymetl (--Ch2cooh) ga rukunin hydroxyl rukuni na Celullulose.
     • Kungiyoyin Carboxymethyl sun ba da izinin kariyar ruwa da halayen anionic ga sarkar sel.
3. Slelluloxyl Slellulose (hec):
   • Tsarin:
     • HEC ya samo asali ne ta hanyar sauya ƙungiyoyin sel na sel tare da Hydrox2oh) ƙungiyoyi.
     • Yana nuna ingantacciyar hanyar samar da ruwa da kuma kayan kwalliya.
4. Methyl Slellulose (MC):
   • Tsarin:
     • Kungiyoyi na MC suna fitowa ta hanyar gabatar da ƙungiyoyi na metyl (-OCH3) zuwa rukunin hydroxyl groups na selulose.
     • Ana amfani dashi yadda ake amfani dashi don riƙewar ta ruwa da kayan aikin fim.
5. Eltyl sel (eC):
   • Tsarin:
     • EC ya hade ta hanyar sauya gungun na sel tare da ethyl (-OC2h5) rukuni.
     • An san shi da insolubility a cikin ruwa kuma galibi ana amfani dashi a cikin samar da mayafin da fina-finai.
6. Slerlulopopropyl Slellulose (HPC):
   • Tsarin:
     • HPC ta samo asali ne ta hanyar gabatar da hydroxypropyl (-och2chhhach3) ƙungiyoyi zuwa ga rukunin hydroxyl groups na selulose.
     • Ana amfani dashi azaman sanyaye, fim na tsohon mai ban sha'awa.

A takamaiman tsarin ya bambanta ga kowane sel mai ma'ana dangane da nau'in da kuma yanayin canji ya gabatar yayin tsarin gyaran. Gabatarwar wadannan kungiyoyin enter suna ba da takamaiman kaddarorin ga kowane ethulose ether, mai sanya su ya dace da aikace-aikace daban-daban na masana'antu daban-daban.
