1. For the catalytic reaction of methane and ammonia to form hydrogen cyanide, bariumoxide (baryta, BaO) was added to alumina to increase the activity of the latter.　2. On the barium-aluminium combination, the influence of barium oxide on the yield of hydrogen cyanide was seen to be negative, indicating the suppression of activity of alumina gel. After all, it was confirmed that baryta did not act as promoter but as catalyst poison. In other words, baryta, either alone or with the addition of alumina, did not form the suitable catalyst for the synthesis of hydrogen cyanide.　3. In the case of binary composition consisting of baryta and alumina, it would be interesting to note that the catalyst having the corresponding composition to the spinel form, i. e. BaAl_2O_4, was seen to have the worst activity or nearly so; though the best activity was favoured in the case of the spinel form composed of magnesia and alumina.
