Among nitrate, sulphate and chloride of aluminium, the last, i. e. aluminium chloride, was found to be the most suitable to make the hydrogen cyanide synthetic catalyst of alumina made of both aq. solution of the above mentioned salt and aq. ammonia, as the decomposition rate of ammonia was low, while alminium sulphate was unsuitable to be adopted as catalyst, as the alumnia gel made of this compound decomposed a considerable amount of ammonia and hydrogen sulphide was produced in the process.　By means of ”aging” in hot water for several hours, catalytic activity changed favourably for increasing hydrogen cyanide yield.　To explain the relation between the adsorptive power of ammonia gas as ”adsorbent” and the catalytic activity to synthesize hydrogen cyanide as ”catalyst,” the alumina gel was examined, and was found to have excellent catalytic activity as well as superior adsorptive power. Therefore it was confirmed that to carry out, beforehand, adsorption examination with ammonia and compare the results with those of standard catalysts was a good means of securing a successful hydrogen cyanide synthetic process.
