I-Hydroxypropyl starch ether-HPS

I-Hydroxypropyl starch ether (HPS) yimveliso yesitatshi eguqulwe ngokwekhemikhali efumana ukusetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa. Le ngqungquthela ifunyenwe ngokuphendula isitashi ngepropylene oxide, ekhokelela ekutshintsheni amaqela e-hydroxyl kwi-molecule ye-starch kunye namaqela e-hydroxypropyl. Imveliso ephumayo ibonisa ukunyibilika kwamanzi okuphuculweyo, uzinzo, i-viscosity, kunye neempawu zokwenza ifilimu xa kuthelekiswa nesitashi somthonyama.

1. Ulwakhiwo kunye neePropati:

IHydroxypropyl starch ether inesakhiwo esintsonkothileyo esibangelwa kukuguqulwa kwemolekyuli yesitatshi. Isitashi yipolysaccharide eyenziwe ngeeyunithi zeglucose ezidityaniswe ngamabhondi e-glycosidic. Inkqubo ye-hydroxypropylation ibandakanya ukutshintshwa kwamaqela e-hydroxyl (-OH) kwi-molecule ye-starch kunye namaqela e-hydroxypropyl (-OCH2CHOHCH3). Olu hlengahlengiso luguqula izinto ezibonakalayo kunye neekhemikhali zesitashi, zinika iimpawu eziphuculweyo.

Iqondo lokutshintsha (DS) yiparamitha ebalulekileyo emisela ubungakanani behydroxypropylation. Imele inani eliqhelekileyo lamaqela e-hydroxypropyl aqhotyoshelwe kwiyunithi nganye ye-glucose kwi-molecule ye-starch. Amaxabiso aphezulu e-DS abonisa iqondo elikhulu lokuguqulwa, okukhokelela kutshintsho oluphawulekayo kwiipropati zesitashi.
