A METHOD FOR PRODUCING AN ALKYLATE SUITABLE FOR USE IN THE MANUFACTURE OF DETERGENT WHICH COMPRISES CONTACTING A MIXTURE OF OLEFINIC HYDROCARBONS HAVING 6 CARBON ATOMS IN THE MOLECULE AND CONTAINING TYPE I, II, III, AND IV OLEFINS AND HEXANES AT A TEMPERATURE IN THE RANGE BETWEEN 175* AND 225* F. WITH SULFURIC ACID HAVING A TITRATABLE ACIDITY NO LESS THAN 70% H2SO4 UNDER EQUILIBRIUM CONDITIONS TO FORM A POLYMERIZED PRODUCT, DISTILLING SAID PRODUCT OF SAID OLEFINS TO RECOVER A POLYMER CONTAINING 12 CARBON ATOMS IN THE MOLECULE, ADMIXING THE POLYMER WITH AN AROMATIC HYDROCARBON HAVING 6 TO 8 CARBON ATOMS IN THE MOLECULE, ALKYLATING THE AROMATIC HYDROCARBON IN SAID ADMIXTURE WITH THE OLEFINIC POLYMER TO FORM AN ALKYLATE AND RECOVERING SAID ALKYLATE.
