1,2,3,4-Tetrahydronaphthalene

1,2,3,4-Tetrahydronaphthalene

Medical Intermediate with High Purity
Chemical Structure 1,2,3,4-Tetrahydronaphthalene

Product Properties Applications

Paint coating: 1,2,3,4-tetrahydronaphthalene is used in high-grade paints to improve smoothness and gloss.

Chemistry and chemical engineering: with a high boiling point, 1,2,3,4-tetrahydronaphthalene has low evaporation even at 180°C; therefore, it can be used as a high-boiling-point solvent, and can be used for producing lubricants and Alpha-Tetralone.

Pesticides: largely used for producing 1-Naphthol, the intermediate for the insecticide carbaryl. Tetrahydronaphthalene is oxidized with air in the liquid phase to generate naphthalene ketone or tetralin alcohol. After dehydrogenation, naphthalene ketone will produce alpha naphthol.

Heat carrier: 1,2,3,4-tetrahydronaphthalene is an important raw material for synthesizing the high-temperature heat carrier SCHULTZ S760 (1,2-Diphenylethane).
