Claim 1
Independent Claim
111 words
A PROCESS FOR CONVERTING A FIRST HYDROCARBON CONTAINING AT LEAST THREE CARBON ATOMS PER MOLUECULE AND CONTAINING NON-AROMATIC CARBON-TO-HYDROGEN BONDS INTO AT LEAST A SECOND HYDROCARBON HAVINGS A HIGHER CARBONTO-HYDROGEN RATIO WHICH COMPRISES SUBJECTING A VAPOR MIXTURE COMPRISING SAID FIRST HYDROCARBON, A HYDROGEN ACCEPTING OLEFIN HAVING A LOWER CARBON NUMBER THAN SAID FIRST HYDROCARBON AND A REACTANT IODINE SPECIES IN SUFFICIENT AMOUNT TO FURNISH AT LEAST 0.05 MOLE OF IODINE PER MOLE OF SAID FIRS: HYDROCARBON TO A TEMPERATURE OF AT LEAST 300*C. TO EFFECT A C-TO-H BOND CLEAVAGE IN SAID FIRST HYDROCARBON AND CONVERSION OF AT LEAST PART OF SAID OLEFIN TO THE CORRESPONDING PARAFFIN, AND RECOVERING SAID SECOND HYDROCARBON.
