Description
Otto 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.

Uses
OFII 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.
