Abstract

PURPOSE: To maintain the titled compound useful as a solvent for dry-cleaning, etc., stable without coloring, by the addition of glycidyl methacrylate, an acetylene alcohol and a specific amine to perchloroethylene.
CONSTITUTION: Three components of (A) glycidyl methacylate in an amount of 0.005W5% based on perchloroethylene (P), (B) an acetylene alcohol in an amount of 0.005W5% based on (P), and (C) an amine selected from cyclohexyl- and dicyclohexylamines in an amount of 0.0002W0.05% based on (P) are added to stabilize the perchloroethylene (P). The addition of a phenol, e.g. thymol or guaiacol, in an amount in the range of 0.001W0.5%, to the above-mentioned three components, may further improve the stabilizing effects.
