Xylitol, kana yaomeswa, ine isingasviki 98.0% yeC5H12O5.
Tsanangudzo Xylitol inoitika semakristasi machena kana hupfu.Haina hwema uye inonaka.
Inonyungudika mumvura, inonyungudika zvishoma mu ethanol (95).
Zviri hygroscopic.
Kuzivikanwa (1) Ku 1 mL yemushonga weXylitol (1 mu2) wedzera 2 mL yesimbi (II) sulfate TS uye 1 mL yemushonga wesodium hydroxide (1 mu5): ruvara rwebhuruu-ruvara runogadzirwa pasina turbidity. .
(2) Sarudza iyo infrared absorption spectrum yeXylitol, yakamboomeswa, sekurairwa munzira ye potassium bromide disk pasi peInfrared Spectrophotometry <2.25>, uye enzanisa iyo spectrum neReferensi Spectrum: ese ari maviri anoratidza kusimba kwakafanana kwekunyura pane imwechete wave nhamba. .
