Abstract

(1) The catalytic action of Japanese acid earth on naphthalene is greatly promoted when it contains the “retained water”, designated temporarily by the present author.
(2) The molecules of the “retained water” may be replaced by those of several other neutral substances containing oxygen in their molecules, the catalytic activity of the earth being thereby raised to a greater or smaller extent according to the nature of the substance.
(3) The term “degree of promotion” has been introduced, and the relation between the degree of promotion and molecular affinity has been discussed.
(4) The nitrogen-containing substances such as ammonia, methylamine, acetonitrile, and amyl nitrite have been found to be strong poisons to the catalysis, while the acidic substances such as hydrogen chloride and acetic acid have proved to be quite weak poisons.
(5) Chloroform, carbon tetrachloride, chlorobenzene, and many hydrocarbons have been found indifferent to the catalytic action.
