Abstract
Pure xylitol was prepared in a good yield by the catalytic reduction of d-xylose under high pressure, using a Ni-Fe catalyst. Xylitol was recrystallized from alcohol, methanol or dioxane. New crystalline xylitol derivatives, pentabenzoyl-xylitol (m. p.105_??_6°), tetrabenzoyl-xylitol (m. p.162.3°) and 1, 5-ditrityl-xylitol-tribenzoate (m. p. 197_??_8°) were synthesized. Pure crystalline 1, 5-ditrityl-xylitol-triacetate was also obtained from alcohol.
