Otto fuel II - Definition

Otto Fuel II is a stable liquid composed of a nitrate ester in solution with a desensitizing agent and a stabilizer.

Otto (or OTTO) fuel is a monopropellant used mainly in torpedoes as they need a high-output energy source while submerged. It doesn't need exposure to any oxidant to ignite and release energy as its three components, propylene glycol dinitrate (the major component), 2-nitrodiphenylamine, and dibutyl sebacate will react between themselves whenever vaporised and heated. Needing no oxidants, usually very unstable substances, makes Otto ideal for use in the constrained environment of a submarine. Also, the amount of energy it can release far surpasses the capacity of the electric battery used in older torpedoes

OTTO fuel II is a toxic substance [1] (http://www.atsdr.cdc.gov/tfacts77.html) found in EPA's National Priorities List. Ingestion of contamined food or direct exposure at worksites can cause headaches, poor eye-hand coordination, eye irritation, congested noses, nausea, dizziness, and difficulty breathing. No fatal cases of overexposure have been reported.
