117 words
IN THE METHOD OF CHLORINATING TITANIUM BEARING MATERIALS IN A REACTION ZONE WHEREBY HEAT IS EVOLVED AND TITANIUM TETRACHLORIDE IS FORMED AND VAPORIZED, THE IMPROVEMENT WHICH COMPRISES CONDUCTING SAID REACTION AT A RATE IN EXCESS OF THE RATE AT WHICH HEAT EVOLVED BY THE REACTION IS REMOVED FROM THE REACTION ZONE BY CONDUCTION, RADIATION, AND CONVECTION, WHEREBY THE TEMPERATURE OF THE REACTION ZONE TENDS TO RISE, AND PREVENTING EXCESSIVE RISE OF THE TEMPERATURE OF SAID ZONE BY INTRODUCING THEREIN A METAL CHLORIDE IN AN UNVAPORIZED STATE, WHICH CHLORIDE VAPORIZES AT A TEMPERATURE ABOVE 50* C. AND BELOW 800* C., THE AMOUNT OF SAID CHLORIDE SO INTRODUCED BEING LARGE ENOUGH TO EFFECT SUBSTANTIAL COOLING OF THE REACTION ZONE.
