Isobutyl benzene and a process for synthesis of isobutyl benzene by using a catalyst

A process for the synthesis of isobutyl benzene, said process comprising the following steps:

• a) preparing a catalyst by reacting active metal and support, in-situ, under vacuum at a temperature in a range of 200° C. to 400° C. in a reactor, wherein said catalyst comprises an active metal doped on a support, wherein said support is a metal carbonate support which is at least one selected from the group consisting of potassium carbonate (K2CO3), sodium carbonate (Na2CO3), cesium carbonate (CS2CO3), and rubidium carbonate (Rb2CO3), and wherein said support has a particle size in a range of 15 nm to 30 nm;
• b) cooling said reactor at a temperature in a range of 25° C. to 40° C. and introducing a predetermined amount of toluene in said reactor;
• c) charging a predetermined amount of propylene gas in said reactor by maintaining a temperature in a range of 25° C. to 40° C. to obtain a propylene toluene mixture;
• and
• d) heating said mixture at a temperature in a range of 130° C. to 190° C., to obtain isobutyl benzene.
