Abstract

1. A process for the manufacture of 1-phenyl-1,3,3-trimethylindan by dimerization of varies-methylstyrene in the presence of acid catalysts, characterized in that varie-methylstyrene in a pure state or dissolved in an inert solvent is brought into contact with a catalyst at a temperature of 60-140 degrees C for a contact period of 5-200 minutes, the catalyst being obtained in the usual manner by treating dried and pulverized bentonite with concentrated sulphuric acid without subsequent scrubbing, the amount of sulphuric acid being 0.5-1.5 equivalents per equivalent of bentonite based on the ion exchange capacity of the bentonite, and the amount of catalyst being 0.5-50 % by weight, based on the total weight of the reaction mixture.
