Boiling Point:384ºC
Refractive Index:1.590
Water Solubility:SOLUBLE IN COLD WATER
Storage Conditions:Store in a cool, dry place. Store in a tightly closed container.
Vapor Pressure:2.27X10-7 mm Hg at 25 deg C (est)
Henrys Law Constant:Henry's Law constant = 1.73X10-11 atm-cu m/mol at 25 °C (est)
Experimental Properties:Hydroxyl radical reaction rate constant = 6.74X10-12 cu cm/molec-sec at 25 °C (est)
Air and Water Reactions:Insoluble in water.
Reactive Group:Amides and Imides
Reactivity Profile:A halogenated amide. Organic 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).
