Abstract

The sublimate melted at 215-217" (from Skellysolve C) and was identical with the mixture of dimethylanthra- cenes obtained previously. A mixture of benzhydrol (25 g.) , diphenylmethane (60 cc.) and aluminum chloride (56 9.) maintained for three hours at 60" yielded 40.43 g. of non-volatile product. Vacuum distillation at 180-210° (1 X mm.) yielded 16.0% of dibenzylanthracene, mp 191-192 O, which was spectroscopically identical with the ...
