| titleOfInvention | Process for the preparation of 2,6-dihydroxynaphthalene |
| abstract | Process for the preparation of 2,6-dihydroxynaphthalene from 2,6-dialkylnaphthalenes, which are dissolved in an inert solvent and are oxidized at temperatures from 50° to 150° C. by means of oxygen or oxygen donors, in the presence of an alkali metal salt or alkaline earth metal salt of an organic carboxylic acid having 5 to 14 carbon atoms, to give the corresponding 2,6-dialkylnaphthalene dihydroperoxides, and the latter are subsequently hydrolysed. n The process results in pure, easily isolatable products in a good yield. The process products according to the invention are valuable intermediates for, inter alia, dyes, plastics, synthetic fibres, polymeric liquid crystals or pharmaceuticals. |
