Procedure

The first fraction (containing hydrogen) is re-used in the reaction step with acetone and benzene, the second fraction (containing water) is removed from the process, the third fraction (containing benzene) is partly re-used in the reaction step with acetone and hydrogen and partly in a subsequent reaction step, called transalkylation step, where it is reacted with the fifth fraction (containing polyisopropylbenzenes) to produce again the desired product isopropylbenzene.
