520 _aResumen del autor, extraído del trabajo. The importance of isopropylbenzene (Cumene) has made isopropylation reactions the most widely studied using a wide range of catalysts such as Lewis acids (metal halides) i.e. aluminum chloride, and inorganic acids (Bronsted acids) i.e. sulphuric acid, hydrofluoric acid, supported phosphoric acid, and zeolite. Therefore, in order to produce higher yield of isopropylbenzene from diisopropylbenzenes which are the results of the above isopropylation processes, a series of isomerization and transalkylation reactions of p- and m-diisopropylbenzenes in the presence of trifluoromethanesulphonic acid (triflic acid) as catalyst with different molar ratios 1:1, 1:3 and 1:6 of catalyst to each isomer were carried out in liquid phase under atmospheric pressure and room temperature.
