Isitatshi seHydroxypropyl ether-HPS

I-Hydroxypropyl starch ether (HPS) sisixhobo esiguqulwe ngokweekhemikhali esisetyenziswa kakhulu kumashishini ahlukeneyo ngenxa yeempawu zaso ezikhethekileyo. Le khompawundi ifunyanwa ngokuphendula istarch nge-propylene oxide, nto leyo ekhokelela ekutshintshweni kwamaqela e-hydroxyl kwimolekyuli yestarch ngamaqela e-hydroxypropyl. Imveliso ephumayo ibonisa ukunyibilika kwamanzi, uzinzo, i-viscosity, kunye neempawu zokwenza ifilimu xa kuthelekiswa nesitatshi sendalo.

1. Ulwakhiwo kunye neempawu:

I-Hydroxypropyl starch ether inesakhiwo esintsonkothileyo esibangelwa kukuguqulwa kwemolekyuli yesitatshi. Isitatshi yi-polysaccharide eyenziwe ziiyunithi zeglucose ezidityaniswe ziibhondi ze-glycosidic. Inkqubo ye-hydroxypropylation ibandakanya ukutshintshwa kwamaqela e-hydroxyl (-OH) kwimolekyuli yesitatshi ngamaqela e-hydroxypropyl (-OCH2CHOHCH3). Olu tshintsho lutshintsha iipropati zomzimba nezekhemikhali zesitatshi, nto leyo enika iimpawu eziphuculweyo.

Iqondo lokutshintshwa (DS) liyiparameter ebalulekileyo emisela ubungakanani be-hydroxypropylation. Limele inani eliqhelekileyo lamaqela e-hydroxypropyl anamathele kwiyunithi nganye yeglucose kwimolekyuli yesitatshi. Amaxabiso aphezulu e-DS abonisa inqanaba elikhulu lokuguqulwa, okukhokelela kutshintsho olukhulu kwiimpawu zesitatshi.
