Abstract 1. IN A PROCESS FOR THE THERMAL HALOGENATION OF A FEED STOCK CONTAINING A C9-C18 N-PARAFFIN BY REACTION, OF SAID FEED STOCK IN LIQUID PHASE WITH CHLORIDE OR BROMINE, WHEREIN CARBONYL- AND HYDROXYL-CONTAINING HYDROCARBONACEOUS COMPOUNDS FORMED BY AIR OXIDATION OF SAID PARAFFIN ARE PRESENT IN SAID FEED STOCK IN CONCENTRATION OF ABOUT 0.001 TO 1.0 WT. PERCENT, THE IMPROVEMENT WHICH COMPRISES REMOVING FROM SAID FEED STOCK, PRIOR TO SAID THERNAL HALOGENATION, AT LEAST A PORTION OF SAID CARBONYL- AND HYDROXYLCONTAINING COMPOUNDS BY CONTACT OF THE FEED STOCK WITH A SOLID SORBENT OF DEHYDRATED SILICA GEL OR ACTIVATED ALUMINA CAPABLE OF SELECTIVELY SORBING SAID COMPOUNDS FROM THE FEED STOCK, WHEREBY TO INCREASE THE RATE OF HALOGENATION OF SAID N-PARAFFIN.
