Khoom Description
Dab tsi yog beta -D-Glucose pentaacetate?
Beta-D-Glucose pentaacetate yog dawb crystalline hmoov uas tsis muaj solubility hauv dej, tab sis nws tuaj yeem tawg mus rau hauv dej los tsim cov tshuaj colloidal; Nws yog soluble hauv qee cov kuab tshuaj organic xws li chloroform, dichloromethane, thiab lwm yam.; nws muaj kev ruaj ntseg zoo, thiab nws tuaj yeem tiv taus qee qhov kub thiab pH hloov pauv . -D-Glucose Pentaacetate yog siv rau hauv kev sib txuas thiab kev kawm ntawm lwm cov organic tebchaw, xws li levulose acetate pentasaccharide.
Kev siv ntawm beta-D-Glucose pentaacetate:
1.Beta-D-Glucose pentaacetate yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis, siv los tsim ntau cov carbohydrate derivatives thiab cov organic tebchaw nrog cov qauv qab zib.
2.Nws tuaj yeem siv los ua kev tiv thaiv pab pawg reagent los tiv thaiv pawg hydroxyl ntawm cov piam thaj lossis lwm yam carbohydrates, ua kom muaj kev xaiv tshuaj lom neeg ntawm cov haujlwm tshwj xeeb.
3.It ua hauj lwm raws li ib tug chiral induction reagent nyob rau hauv asymmetric synthesis tshua, coj cov tshuaj tiv thaiv mus rau hauv ib tug tshwj xeeb chiral kev taw qhia rau cov synthesis ntawm optically active tshuaj thiab tej yam ntuj tso khoom.
