Procedure

1.2 g of 4'-(trans-4-n-pentylcyclohexyl)-biphenyl-3,4-dicarboxylic acid anhydride, 2.0 g of hydroquinone and 10 g of oxalic acid are heated for 2 hours to 220°. After cooling, the 1,4-dihydroxy-6-[4-(trans-4-n-pentylcyclo-hexyl)-phenyl]-anthraquinone obtained is purified by recrystallization from ethanol.
