The kinetics of alkylation of xylenes with acetaidehyde/paraidehyde, with sulfwic acid (86.598% w/w) as a catalyst in a tw+phase system to give dlxylylethmes, was studied in the temperature range of -13 to -3 O C . Two mechanically agitated contactors, one of 8.5 cm i.d. and the other of 11 cm i.d., were used and it was possible to eliminate mass transfer resistance. Experiments were conducted in batch as well as continuous modes of operation. The reaction was found to be first order with respect to xylene as well as acetaldehyde (concentration
