ABSTRACT:
This invention discloses an integrated process of alkylation of olefins and regeneration of spent sulfuric acid. The alkylation of olefins may be replaced by nitration of toluene or by chlor-alkali process. The sulfuric acid is used as a catalyst or a absorbent, and the spent sulfuric acid is regenerated in situ and is recycled in the alkylation of olefins, nitration of toluene or chlor-alkali processes.
