Treating low reactivity alkylating agents in the vapor phase with catalysts converts the low reactivity alkylating agents to high reactivity alkylating agents. The alkylating agents are useful in synthesis of alkyl aromatics with Lewis acid catalysts.

Catalytic process for making high reactivity alkylating agents and

In one embodiment,the invention relates to a formed copper chromite catalyst prepared from a blend comprising from about 20 to about 80% by weight of copper chromite and from about 20 to about 80% by weight of at least one extrudable inorganic binder material wherein the catalyst has a surface area of from about 20 to about 225 m.sup.2 /g, and the total pore volume of the pores in said catalyst having a diameter of up to about 95,000 .ANG. is between about 0.35 to about 1 cc/g. In another embodiment, the invention relates to a process for preparing the formed copper chromite catalyst of the invention, and the process comprises
