1. Chemical aha: Hydroxypropyl starch ether

2. English aha: Hydroxypropylstarch ether

3. Ndebiri Bekee: HPS

4. Usoro ihe omimi: C7H15NO3 Molecular mass: 161.20

5. Usoro nkwadebe: Hydroxypropyl starch bụ starch emezigharịrị nke kemịkalụ, nke a na-emepụta site na propylene oxide na starch iji dochie otu hydroxyl n'ime usoro starch macromolecule ka ọ ghọọ ụdị starch etherified.

6. Njirimara anụ ahụ: ọcha (enweghị agba) ntụ ntụ nwere ezigbo mmiri na mmiri dị mma, ngwọta mmiri ya na-apụta ìhè na enweghị agba, ma nwee nkwụsi ike dị mma. Ọ kwụsiri ike na acid na alkali, ọnọdụ okpomọkụ dị ala karịa nke starch obodo, na mgbanwe nke viscosity na-ekpo ọkụ na oyi na-esikwu ike karịa nke starch obodo. Ịgwakọta na nnu na sucrose enweghị mmetụta na viscosity. Mgbe etherification gasịrị, ma nkwụsi ike nke ice na-agbaze na nghọta ka mma.

7. Njirimara kemịkalụ: ihe onwunwe nke ihe ndị na-emepụta starch na ihe ndị na-emepụta hydroxypropyl, glucose unit na-emepụta starch nwere 3 hydroxypropyl ìgwè nke nwere ike dochie, ya mere, ngwaahịa nwere dị iche iche degrees nke nnọchi nwere ike nweta.

8. Nka na ụzụ na-egosi Ọdịdị: ọcha ntụ ntụ, dị mfe itinye mmiri mmiri

Solubility: Nwere ike igbari n'ime mmiri wee ghọọ ihe ngwọta na-enweghị atụ

Viscosity (ihe ngwọta mmiri 5%, 20℃): 500-20000 mPa.s

Uru PH (2% ngwọta mmiri): 8-10
