TH-dimer, also called tetrahydromethylcyclopentadiene dimer[1] or RJ-4, is a liquid fuel used in missiles. For example, TH-dimer is used in the turbofan engine of the BGM-109 Tomahawk cruise missile. It is also a component of the jet fuel JP-9.
The fuel is non-volatile so it is safe to use on ships or submarines. It has a high flash point minimum of 60 °C.[2]
Chemically, TH-dimer is a mixture of isomeric saturated hydrocarbons derived from hydrogenation of the dimer of methylcyclopentadiene.[3]
