Hydroxypropyl istaarijka ether-HPS

1. Magaca kiimikada: Hydroxypropyl starch ether

2. Magaca Ingiriisiga: Hydroxypropylistaarijka ether

3. Soo gaabinta Ingiriisiga: HPS

4. Qaaciidada molecular: C7H15NO3 cufka unugyada: 161.20

5. Habka diyaarinta: Hydroxypropyl istaarijku waa istaarij kiimikaad la beddelay, kaas oo ay ka ethered by propylene oxide iyo istaarij si ay u beddelaan kooxda hydroxyl ee qaab-dhismeedka macromolecule istaarijka si ay u noqdaan nooc ka mid ah istaarijka etherified.

6. Qalabka jirka: budo cad (midab la'aan) oo leh dareere wanaagsan iyo biyo wanaagsan oo milmaya, xalkeeda aqueous waa mid hufan oo aan midab lahayn, waxayna leedahay xasillooni wanaagsan. Waxay u xasiloon tahay aashitada iyo alkali, heerkulku wuu ka hooseeyaa kan istaarijka wadaniga ah, iyo isbeddelka viscosity kulul iyo qabow waa ka xasilloon yahay kan istaarijka wadaniga ah. Isku qas milix iyo sukrose wax saameyn ah kuma laha viscosity. Etherification ka dib, xasiloonida baraf-dhalashada iyo daah-furnaanta labadaba waa la hagaajiyay.

7. Waxyaabaha kiimikaad: sifooyinka istaarijka ee leh beddelka hydroxypropyl, unugga gulukooska ee ka kooban istaarijku wuxuu leeyahay 3 kooxood oo hydroxypropyl ah oo la bedeli karo, sidaas darteed alaabooyinka leh heerar kala duwan oo beddelaad ah ayaa la heli karaa.

8. Tilmaamaha farsamada Muuqaalka: budada cad, si sahlan loo nuugo qoyaanka

Solubility: Waxay ku milmi kartaa biyaha oo waxay noqon kartaa xal hufan

Viscosity (5% xal aqueous, 20℃): 500-20000 mPa.s

Qiimaha PH (2% xal aqueous): 8-10
