Ribitol or adonitol is a sugar alcohol with the formula C5H12O5. It is an isomer of xylitol.
Contents
Properties
Chemical
Ribitol will burn if mixed with an oxidizer and ignited.
Physical
Adonitol is a crystalline colorless solid, soluble in water.
Availability
Ribitol is sold by chemical suppliers. Can also be found online as sweetener.
It occurs naturally in Adonis vernalis.
Preparation
Can be obtained from the reduction of ribose.
Projects
- Sweetener
- Grow beautiful crystals
- Component of eutectic solvent for inhibiting growth of bacterial cell[5]
Handling
Safety
Ribitol has low toxicity, though it's not commonly used as sweetener as it's more expensive than other sugar alcohols.
Storage
No special storage is required, a plastic bottle will suffice.
Disposal
No special disposal is required. Discard it as you wish.
