Mannitol is a type of sugar alcohol used as a sweetener in diabetic food, as well as medication for lowering blood pressure.
Mannitol can be nitrated to mannitol hexanitrate using a nitrating mixture, in a process similar to that for ETN.
Mannitol is a colorless crystalline solid, which dissolves in water. Like all sugar alcohols, it is insoluble in hydrocarbons.
Mannitol is sold in many food stores and pharmacies.
It can also be bought online in large amounts.
Mannitol is much cheaper to purchase than synthesize, or extract it from plants.
- Sugar substitute
- Medication for lowering blood pressure
- Make mannitol hexanitrate
Mannitol has low toxicity. It is commonly used as sugar substitute, as well as medication for lowering blood pressure, used to decrease high pressures in the eyes for glaucoma, and to lower increased intracranial pressure.
Mannitol should be stored in closed plastic or glass bottles. No special storage is required.
No special disposal is required. Discard it as you wish.
