Abstract

Dichloromethane compsns. are stabilised against degradation by reaction with aromatic or aliphatic cpds. in the presence of metals, metal halides of their mixt. by the addn. of 0.001-2 wt.% of diisopropylamine, N-methylpyrrole, butylene oxide or propylene oxide. Pref. 0.002-u wt.% of stabiliser is added. Partic. useful for stabilisation in presence of Al, Fe and Zn or their halides. Pref. used for metal degreasing.
