Beschreibung

Früher wichtig bei der Herstellung von Farbstoffen, als Vorstufe zu Phthalsäureanhydrid

Naphthalene is formerly important in dyestuff manufacture. It acts as a precursor to phthalic anhydride. Naphthalene is used in the manufacturing of phthalic anhydride, naphthalene sulfonic acids and hydrogenated naphthalenes such as 1,2,3,4-tetrahydronaphthalene, which is used as a precursor for various dyestuffs, pigments, rubber processing chemicals and in pharmaceuticals. Its molten form is used as solvent replacing the high- boiling solvents like dichlorobenzene, nitrobenzene and durene. It is involved as reaction medium for in the Diels-Alder reaction between C60 with anthracene.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
