Claim 1
Independent Claim
136 words
A METHOD FOR ALKYLATING A PARAFFIN HAVING AT LEAST THREE AND NO MORE THAN FIVE CARBON ATOMS WITH A MONO-OLEFIN HAVING AT LEAST THREE AND NO MORE THAN FIVE CARBON ATOMS PER MOLECULE WHICH COMPRISES REACTING A MIXTURE OF SAID PARAFFIN AND OLEFIN IN WHICH THE PARAFFIN IS IN EXCESS OF THE OLEFIN IN A REACTION ZONE AT A TEMPERATURE IN THE RANGE OF 80* F. TO 750* F. AT A PRESSURE AT LEAST ATOMOSPHERIC IN THE PRESENCE OF MERCURY AS A SENSITIZER BY EXPOSING A CONTINUOUS STREAM OF SAID MIXTURE FLOWING THROUGH SAID REACTION ZONE CONTAINING SAID SENSITIZER UNDER SAID CONDITIONS OF TEMPERATURE AND PRESSURE TO A RESONANCE ENERGY FREQUENCY CORRESPONDING AT LEAST TO ONE OF THE RESONANCE LINES OF THE SENSITIZER FOR A TIME OF APPROXIMATELY 4 MINUTES TO FORM A SATURATED BRANCHED PRODUCT.
