PURPOSE:To provide a process for high-efficiency production of 2,7 dihydroxy-9,10-dihydrophenanthrene which is important as a constituent element for liquid crystals from 2,7-dibromo-9,10-dihydrophenanthrene. CONSTITUTION:A production process for 2,7-dihydroxy-9,10-dihydro-phenanthrene which is characterized by reaction of 2,7-dibromo-9,10-dihydrophenanthrene with an alkali metal hydroxide in the presence of a copper catalyst in an aqueous solution containing an alcohol of 1 to 3 carbon atoms. |
