Experimental work, carried out in a jacketed glass reactor, consists in treating 50 ml of the previously mentioned solutions by 25 ml of 1,4-dioxan which is expected to precipitate magnesium chloride as MgCl 2 Â·6H 2 OÂ·C 4 H 8 O 2 (Barnes and Weakley, 1976, Bester Rogac and Dolar, 1999 and Weicksel and Lynch, 1950).
