OTTOFUELII

BeschreibungOtto Fuel II (OFII) was developed by Dr Otto Reitlinger and introduced by the United States Navy in the mid-1960s as a monopropellant, a propellant consisting of a chemical or mixture that can function on its own without the addition of a separate substance. It is amixture of three chemical constituents, propylene glycol dinitrate, dibutyl sebacate, and 2-nitrodiphenylamine, and has been primarily used as a torpedo propellant due to its ability to combust in the absence of oxygen. The development of OFII was significant given that it increased the speed and range of torpedoes, and despite 50 years in operation, it currently remains in use as a premier torpedo propellant.

VerwendenOFII is used as a propellant for torpedoes and other weapons systems. OFII exists as a reddish-orange, oily liquid with a distinct odor and is a mixture of three chemicals, propylene glycol dinitrate (76%), dibutyl sebacate (22%), and 2-nitrodiphenylamine (1.5%). The largest component of OFII is propylene glycol dinitrate, a colorless liquid also known as 1,2-propylene glycol dinitrate, PGDN, or 1,2-propanediol dinitrate. Propylene glycol dinitrate is a nitrated ester that constitutes the explosive portion of OFII. OFII’s toxicity is largely associated with propylene glycol dinitrate.Dibutyl sebacate, a clear liquid, is added to OFII as a desensitizing agent to stabilize the mixture. Although a significant fraction of OFII, dibutyl sebacate is also used in the production of plastics, including those used for packaging food, and as a flavor enhancer in foods such as nonalcoholic beverages, ice creams, candies, and baked goods. Additionally, it is used as a lubricant in shaving creams. Alternative names for dibutyl sebacate are decanedioic acid, dibutyl ester, sebacic acid, and dibutyl decanedioate. The final component of OFII is 2-nitodiphenylamine, a solid that serves as a stabilizer to control the explosion of propylene glycol dinitrate. It is also used as a solvent dye. 2-Nitrodiphenylamine is also referred to as 2-nitrobenzenamine, 2-nitro-N-phenyl, 2-nitro-N-phenylaniline, and Sudan Yellow 1339.
