This document describes a method for reducing the corrosivity of certain magnesium salts. The salt product resulting from the method exhibits reduced corrosion of steels that come into contact with the salt relative to salt compositions that are not so treated. This makes such treated salts more efficient coolant salts as they will require less equipment replacement over time. The method uses magnesium metal to reduce unwanted impurities in the salts the reduced impurities are then removed as either gas or precipitate from the now purified salt. Without being bound to one particular theory, it is believed that the reduction of the level of impurities in the salt results in a salt with substantially reduced corrosiveness to steel.

It has surprisingly now been discovered that alkoxy-magnesium halides of the general formula ROMgX wherein R is an alkyl having from about 1 to 18 carbon atoms and X is a halide can be synthesized in an inert hydrocarbon in just one step process by reacting magnesium which has been preliminarily activated with small quantities (approximately 5 mol %) of magnesium alkyl with a substantially equimolar mixture of an alkyl halide and an alkanol. That is, the present invention provides a one step reaction process for preparing alkoxy-magnesium halides. This one step reaction process involves reacting magnesium metal which has been previously activated with a magnesium-alkyl compound, with an equimolar mixture of an alkyl halide and an alkanol. Yields in excess of 90% can be obtained by employing the inventive one step reaction process.
