Abstract
Vapor feed containing titanium tetrachloride and ferric chloride vapor is contacted with sodium chloride for complexing said ferric chloride as liquid sodium ferric chloride salt complex while leaving titanium tetrachloride as vapor residue. The salt complex is reacted with molecular oxygen for providing recovered chlorine gas product. Such gas can be recycled to said complexing operation for providing a high grade of chlorine and titanium tetrachloride-rich product. Substantially complete chlorination of ilmenite is a prime source of said vapor feed.
