Tricyclodecane (TCD) is an organic compound with the formula C₁₀H₁₆. It is classed as a hydrocarbon. It has two main stereoisomers–the endo and exo forms.[2] Its primary use in the exo form is as a component of jet fuel.[3] It is used here primarily because of its high energy density. The exo isomer also has a low freezing point.[4][5] Because of this, its properties have been studied extensively.[6][7][8][9][10] It is often called tetrahydrodicyclopentadiene.

Reactions

Its reactions with other materials have been studied,[11][12] as have various production methods.[13][14] The two isomers can interconvert in the presence of aluminum chloride as catalyst absorbed on substrates such as silicon dioxide or zeolites,[15][16][17][18] with preference for forming the exo as the major product.[19][20]
