Hydroxypropyl hmoov txhuv nplej siab ether-HPS

Hydroxypropyl starch ether (HPS) yog cov tshuaj hloov pauv cov hmoov txhuv nplej siab uas pom tau siv dav hauv ntau qhov kev lag luam vim nws cov khoom tshwj xeeb. Cov tshuaj no tau txais los ntawm kev ua cov hmoov txhuv nplej siab nrog propylene oxide, ua rau kev hloov ntawm hydroxyl pawg hauv cov hmoov txhuv nplej siab nrog cov pab pawg hydroxypropyl. Cov khoom ua tau nthuav tawm txhim kho dej solubility, stability, viscosity, thiab zaj duab xis-forming zog piv rau cov hmoov txhuv nplej siab.

1.Structure thiab Properties:

Hydroxypropyl starch ether muaj cov qauv tsim los ntawm kev hloov pauv ntawm cov hmoov txhuv nplej siab. Cov hmoov txhuv nplej siab yog ib qho polysaccharide uas muaj cov piam thaj txuas los ntawm glycosidic bonds. Cov txheej txheem hydroxypropylation suav nrog kev hloov pauv ntawm pawg hydroxyl (-OH) hauv cov hmoov txhuv nplej siab nrog hydroxypropyl pawg (-OCH2CHOHCH3). Qhov kev hloov kho no hloov kho lub cev thiab tshuaj lom neeg cov khoom ntawm cov hmoov txhuv nplej siab, muab cov yam ntxwv zoo dua qub.

Qhov degree ntawm kev hloov pauv (DS) yog qhov tseem ceeb ntawm qhov ntsuas qhov ntsuas ntawm hydroxypropylation. Nws sawv cev rau qhov nruab nrab ntawm cov pab pawg hydroxypropyl txuas rau txhua chav tsev piam thaj hauv cov hmoov txhuv nplej siab. Cov txiaj ntsig DS siab dua qhia tau tias muaj kev hloov pauv ntau dua, ua rau muaj kev hloov pauv tseem ceeb hauv cov hmoov txhuv nplej siab.
