The degradation has been attributed, at least in part, to the combination of the methylene chloride-toluene mixture coming into contact with aluminum chloride and/or iron chloride which has been produced in situ from reaction of the methylene chloride and/or small quantities of the chlorinated impurities remaining in the methylene chloride from its production, with aluminum. On several of these occasions, the degradation was rapid and even explosive. However, on occasion the solvent has degraded in storage. Methylene chloride has been used as a solvent in combination with the aromatic hydrocarbons such as toluene, xylene and the naphthalenes for preparing aluminized paints with little trouble. ![]() for stabilisationīACKGROUND OF INVENTION Methylene chloride is a low boiling chlorinated hydrocarbon, 40 C., which has excellent solvent properties.
