Methacrolein is a chemical compound ( an unsaturated aldehyde) which occurs in the form of a clear flammable liquid that is primarily used for the production of plastics.

Production and representation

Is produced methacrolein by:

Properties

Methacrylaldehyd is a volatile, yellowish liquid with a pungent odor, which is soluble in water. The vapors are heavier than air from methacrolein.

Use

Methacrolein (for example, methyl methacrylate ) resins, pesticides and used as an intermediate for the production of polymers in a small degree of flavor and fragrance materials.

Safety

Methacroleindämpfe is highly irritating to corrosive to mucous membranes, skin and lungs. The vapors of Methacrylaldehyd can form (-15 ° C, ignition temperature 295 ° C flash point) with air to form an explosive mixture.
