APPLICATIONS

Decalin and tetralin are the terms that indicate decahydro- or tetrahydroanaphthalene respectively. They are bicyclic organic compounds; clear liquid used as solvents for resins. Hydroanaphthalenes are produced by hydrogenation of naphthalene in the presence of a catalyst (platinum catalyst).  The commercial decalin is the mixture of cis- and trans- isomers  (typically 77:23) . The trans-isomer is more stable because of less steric interactions. Hydroanaphthalenes are used as industrial solvents for naphthalene, resins, oils, and waxes. It features high boiling point and thermal stability. They are used as components of stove and jet fuels. Hydronaphthalenes are also used as raw materials of functional polymers. They are used in preparing dyes, plasticizers, and insecticides. They are also used in heat transfer fluid, dye carrier,  fuel additives, lubricants, ore flotation and oilfield chemicals. These bicyclic compounds are moieties in transition-metal complex catalysts.

Tetralone is a keto-hydroanaphthalene used as a reactive intermediate which is converted to target compounds including dyes, drugs (contraceptives), and agrochemicals. The alpha-tetralone has carbonyl group on the ring at 1 position while beta-tetralone at 2 position. The different positions provide various chemical structures which offer important roles to colours. Tetralone derivatives find extensive applications in color industry. Their structures are found in pesticides, fragrances and antiseptic agents.
