Chemical properties

colourless liquid

The Uses of Dimethylmorpholine

cis-2,6-Dimethylmorpholine (DMMP) has been used in the preparation of microporous material composed of hybrid T2 and T3 supertetrahedral clusters.

General Description

Clear liquid.

Air & Water Reactions

Highly flammable. Very slightly water soluble.

Reactivity Profile

Dimethylmorpholine reacts with oxidizing agents . Neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

Dimethylmorpholine is combustible.

Flammability and Explosibility

Flammable
