A SULFOCHLORINATION PROCESS COMPRISING IRRADIATING WITH RADIATION CONSISTING OF IONIZING ELECTROMAGNETIC RADIATION HAVING A WAVE LENGTH IN THE RANGE OF 10-S TO 102 A. A REACTION MIXTURE CONSISTING ESSENTIALLY OF A SATURATED HYDROCARBON HAVING IN THE RANGE OF 4 TO 40 CARBON ATOMS PER MOLECULE SELECTED FROM THE GROUP CONSISTING OF PARAFFINS AND NAPHTHENS, 0.1 TO 2.0 MOLES OF SULFUR DIOXIDE PER MOLE OF SAID SATURATED HYDROCARBON, CHLORINE, THE MOLE RATIO OF CHLORINE TO SULFUR DIOXIDE BEING IN THE RANGE OF 0.001 TO 1.0, AND FREE OXYGEN, THE MOLE RATIO OF OXYGEN TO SULFUR BEING IN THE RANGE OF 0.0001 TO 2, AND RECOVERING A MONO-SUBSTITUTED HYDROCARBON SULFONYL CHLORIDE IN AMOUNTS IN THE RANGE OF 2 TO 50 MOLE PERCENT BASED ON SAID SATURATED HYDROCARBON, THE AMOUNT OF HYDROCARBON CHLORIDES PRODUCED BEING LESS THAN 2 MOLES PER MOLE OF SAID SATURATED HYDROCARBON, THE DOSE RATE BEING IN THE RANGE OF 1X10**3 TO 3X10**3 RADS/MIN. AND THE TOTAL DOSE BEING IN THE RANGE OF 10**2 TO 10**10 RADS, BASED ON SAID MONO-SUBSTITUTED HYDROCARBON SULFONYL CHLORIDE.
