Effects of Various Substances on the Anhydrous Aluminum Chloride or Allied Catalyst VI : Effects of Various Metals and Inorganic Salts on the Aluminum Chloride for the Disproportionation of mono-Butyl Naphthalene or mono-Stearyl Naphthalene

摘要

In the preceding paper it was shown that considerably available results had been obtained by the addition of many sorts of metals or inorganic salts to the AlCl_3 or FeCl_3 as the catalyst for the reactions, such as the ketone synthesis, the polymerization of olefins and the alkylation of benzene with alkylchlorides etc. Now the similar studies on the disproportionation of mono-butyl naphthalene or mono-stearyl naphthalene with AlCl_3 are carried out. The results obtained are given in the following summaries. (1) Effects of 11 sorts of metals and 4 sorts of inorganic salts are studied for the disproportionation of mono-butyl naphthalene or mono-stearyl naphthalene with AlCl_3. (2) As the searching of the optimum in respective substance required to obtain the enhanced effect, the mol ratio of these substances to AlCl_3 catalyst were checked. (3) The results obtained for this reaction of mono-stearyl naphthalene resembled considerably with that of stearyl benzene in the preceding reports. (4) As a reason for reversal order of the effect of butyl naphthalene compared with that of stearyl naphthalene, it might be postulated that the isomerization in succeeded by the disproportionation reaction.
