Abstract: AN IMPROVEMENT IN THE METHOD OF PRODUCING ALKYL AROMTIC DISTILLATES HAVING THE BOILING POINT IN THE RANGE OF 230-360* C. AND THE MEAN MOL NUMBER OF ADDED OLEFIN IN THE RANGE OF 1-3, WHICH COMPRISES THE STEP OF BRINGING AN AROMATIC DISTILLATES OTHER THAN THE ABOVE DEFINED ALKYL AROMATIC DISTILLATES INTO CONTACT WITH A SOLID ACID CATALYST NOT CONTAINING ANY HALOGENIDE IN THE PRESENCE OR WITHOUT THE PRESENCE OF OLEFIN HAVING 2-4 CARBON ATOMS WHILE APPLYING SUCH A PESSURE AS BEING SUFFICIENT FOR RETAINING THE LIQUID PHASE OF SAID DISTILLATE OTHER THAN THE ABOVE DEFINED ALKYL AROMATIC DISTILLATES AND A TEMPERATURE IN THE RANGE OF 150-450*C. FOR A RESIDENCE TIME OF 0.5 TO 10 HOURS.
