TH-dimer

TH-dimer, also called tetrahydromethylcyclopentadiene dimer or RJ-4, is a synthetic <a href="/facts/Jet_fuel/4CDswF3t">jet fuel</a> used in jet engines for <a href="/facts/Guided_missile/C5VwQClz">missiles</a>. RJ-4 was originally developed for the <a href="/facts/Ramjet/wFschau9">ramjet</a> engine on <a href="/facts/RIM-8_Talos/sMzh7rYx">RIM-8 Talos</a> naval <a href="/facts/Surface-to-air_missile/2qEW5P07">surface-to-air missile</a>.
The fuel is non-volatile, so it is safe to use on ships or submarines. It has a high <a href="/facts/Flash_point/97JQP35E">flash point</a> minimum of 60 °C (140 °F).
Chemically, TH-dimer is a mixture of <a href="/facts/Isomeric/PXlvDVdg">isomeric</a> <a href="/facts/Saturated_and_unsaturated_compounds/tde2C216">saturated</a> <a href="/facts/Hydrocarbon/Dcg95Ju5">hydrocarbons</a> derived from <a href="/facts/Hydrogenation/l7EzNSA7">hydrogenation</a> of the <a href="/facts/Dimer_(chemistry)/mU64PnEq">dimer</a> of <a href="/facts/Methylcyclopentadiene/9MjNMXX2">methylcyclopentadiene</a>.
