実験手順

24.2 g of diphenic acid (biphenyl-2,2'-dicarboxylic acid) were dissolved in 200 ml of methylene chloride and 1 ml of N,N-dimethylformamide, and 27.9 g of oxalylchloride were dropped in the resultant solution under stirring at room temperature over 30 minutes. After the dropping, the resultant solution was reacted at room temperature for one hour, and the reaction solution was thickened in aspirator vacuum. Methylene chloride and an excessive amount of oxalylchloride were removed from the thickened solution to obtain an oily matter of diphenic acid chloride.
