HPMC Hydroxypropyl Methyl Cellulose CAS No.9004-65-3
Sharaxaada Alaabta
- Hydroxypropyl Methyl Cellulose (HPMC) waa walax dhumuc weyn leh, kala duwanaansho muhiim ah oo ku jirta cellulose aan-ionic ahayn oo isku qasan.
- Hydroxypropyl Methyl Cellulose (HPMC) waa noocyo cellulose ah oo wax soo saarkooda iyo isticmaalkooda ay si xawli ah u kordhayaan sanadihii ugu dambeeyay. Waa eter-ka isku qasan ee aan-ionic-ka ahayn ee laga sameeyay suuf la safeeyey iyada oo loo marayo falcelin taxane ah oo la isticmaalayo propylene oxide iyo methyl chloride sida wakiilada etherification ka dib daaweynta alkalization. Sifooyinkeedu way kala duwan yihiin marka loo eego saamiga maadada methoxy iyo ka kooban hydroxypropyl.
