Sorbitol or glucitol, is a sugar alcohol with a sweet taste, used as a sugar substitute. The most common form is D-sorbitol. It has the chemical formula C6H14O6.

Properties

Chemical

Sorbitol can be nitrated to sorbitol nitrates.

Physical

Sorbitol is a white crystalline solid, with a sweet fruity taste, more pronounced than that of xylitol. It is extremely soluble in water (2350 g/L), acetic acid, ethanol and methanol, but insoluble in most nonpolar solvents. Sorbitol melts at 111 °C and boils between 290–295 °C (values altered by water content).

Availability

Sorbitol is available as sugar substitute in most supermarkets, at various purities and prices. Some brands may have <1% sucralose.

Preparation

Sorbitol can be prepared by reducing glucose with hydrogen.

Projects

  • Sugar substitute
  • Sorbitol nitrate

Handling

Safety

Sorbitol poses little hazard, though if consumed in large quantities is will induce a laxative effect.

Storage

Sorbitol should be kept in closed containers. Since it is hygroscopic, it's a good idea to keep it in a plastic bag inside the storage container.

Disposal

Sorbitol is considered non-toxic and doesn't require special disposal. Can be safely poured down the drain or dumped in the ground.
