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
