and ammonia protects the formamide from the air, and no trouble is encountered unless the heating is interrupted, or unless the heating is continued after the evolution of gases has ceased. Standard Method of Carrying Out the Reaction.Eighty-five grams of benzophenone (0.467 mole) and 110 cc. of 99% formamide (6 X 0.467 mole) (obtained from the Eastman Kodak Co.) together with any substances to be tested for catalytic effect, and a chip of porous plate were placed in a 200-cc. balloon flask equipped with an air-reflux
