Autoignition = 250 °CDecahydronaphthalene (also known as decalin, or as bicyclo [4.4.0] decane), a
bicyclic organic compound , is an industrialsolvent . A colorless liquid with an aromatic odor, it is used as a solvent for manyresin s. It is the saturated analog ofnaphthalene and can be prepared from it byhydrogenation in a fused state in the presence of acatalyst . Decahydronaphthalene easily formsexplosive organic peroxide s upon storage in the presence of air.Isomers
Decahydronaphthalene occurs in
cis andtrans forms. Thetrans form is energetically more stable because of fewersteric interaction s.References
