SECTION 10: Stability and reactivity
10.1 Reactivity
Decomposes on heating. This produces nitrogen oxides. The solution in water is a weak base. Reacts with strong reducing agents. This generates fire hazard.
10.2 Chemical stability
no data available
10.3 Possibility of hazardous reactions
Dust explosion possible if in powder or granular form, mixed with air.N,N'-DIMETHYLUREA is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx).
