Abstract

A process for the preparation of a stable composition for application in the steam degreasing of metals, characterized by the steps of introducing a weight percentage of 0.001 to 2.0 percent of di-isopropylamine in methylene chloride, adding 0.001 to 2.0 percent N-methyl pyrrole, then adding 0.001 to 2.0 percent butylene oxide and propylene oxide, then adding 0.001 to 2.0 percent methyl acetate, acetone, and tertiary amylenes, and finally, optionally adding 0.001 to 2.0 percent methyl alcohol.
