Claim 1
Independent Claim
155 words
A METHOD FOR REACTING A FIRST SATURATED HYDROCARBON WITH A SECOND SATURATED HYDROCARBON WHICH INCLUDES THE STEPS OF FORMING A MIXTURE OF FIRST AND SECOND SATURATED HYDROCARBONS HAVING FROM 1 TO 7 CARBON ATOMS IN THE MOLECULE IN THE INVERSE PROPORTION OF THE NUMBER OF OCCURRENCES OF THE WEAKEST CARBON-HYDROGEN BOND IN EACH MOLECULE OF SAID HYDROCARBONS, FLOWING SAID MIXTURE CONTINUOUSLY THROUGH A REACTION ZONE, EXPOSING THE MIXTURE IN SAID REACTION ZONE TO A RESONANCE FREQUENCY RADIATION OF A WAVE LENGTH OF 2537 A. IN THE PRESENCE OF MERCURY VAPOR AT A TEMPERATURE IN THE RANGE BETWEEN 80* AND 650* F. AT A PRESSURE SUFFICIENT TO MAINTAIN A VAPOR PHASE AT A RESIDENCE TIME IN SAID REACTION ZONE OF ABOUT 4 MINUTES FO FORM A SATURATED PRODUCT HAVING A BRANCHED STRUCTURE AND THE SAME NUMBER OF CARBON ATOMS AS THE SUM OF THE CARBON ATOMS OF THE FIRST AND SECOND HYDROCARBONS, AND RECOVERING SAID PRODUCT.
