Abstract
A nitroalkane-free inhibitor system for methylchloroform has been formulated which contains dioxane, an alkylene oxide, and 3-butyn-1-ol. The stabilizer amounts to about 4 to 6% by volume of the stabilized methylchloroform composition. The stabilized composition is useful in vapor degreasing applications when it additionally contains an alkyl nitrate.
