Abstract
PURPOSE: To stabilize methylene chloride economically by adding and mixing a small amount of an alicyclic amine compound.
CONSTITUTION: Methylene chloride is stabilized by the addition of an effective amount of an alicyclic amine compound such as cyclohexylamine, dicyclohexylamine, pyrrolidine, etc. The amount of the amine is 0.00001-0.01 part by weight per 100 parts by weigth of methylene chloride. Th eonventional stabilizers for other chlorinated hydrocarbon solvents, such as phenols, alcohols, etc., is not effecive to methylene chloride.
USE: Extrcting solvent for the production of polycarbonates, reaction solvent, foaming agent for synthetic resins, etc
