Abstract
A method for dehydrating magnesium chloride hydrates or brines by complexing with amine hydrochlorides is described. Magnesium chloride hydrate or brine is reacted with an amine hydrochloride to form a complex which is then heated to first drive off water and then at a more elevated temperature to decompose the anhydrous complex into anhydrous magnesium chloride and amine hydrochloride. Any magnesium oxides present in the starting material is converted to the chloride by reaction with the HCl present.
