Effects of Various Substance on the Anhydrous Aluminum Chloride or Allied Catalyst II : Effects of Various Metals and Inorganic Salts on the Aluminum Chloride or Ferric Chloride for the Polymerization of Olefins

摘要

In the previous paper, about 10% increase of yields were shown by the addition of many sorts of metals, alloys and inorganic salts to the FeCl_3 a catalyst for the two kinds of the reaction of ketone-synthesis. Now the similar studies on the polymerization of olefins are carried out using AlCl_3 or FeCl_3 catalyst accompanied with various metals or inorganic salts, because these reactions are known to have the mechanism followed by the way of addition with HCl, but not produce HCl as the byproduct differing from the reaction of ketone-synthesis. The results obtained are given in the following summary. (I) Effects of the 13 sorts of metals and 6 sorts of inorganic salts are studied for the polymerization of 3 sorts of olefins i.e. cetene, dodecene and cyclohexene with AlCl_3 or FeCl_3. (II) Many sorts of metals and inorganic salts gave the positive effects, but others of these substance gave the negative effects. (III) These results roughly resembled with the outline for the effect of various metals and inorganic salts in the previous report.
