发明名称 Process for the preparation of 2,6-dihydroxynaphthalene
摘要 Process for the preparation of 2,6-dihyroxynaphthalene from 2,6-dialkylnaphthalenes, which are dissolved in an inert solvent and are oxidized at temperatures from 50 DEG to 150 DEG 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. 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.
