Acrolein flash point

Flammability Acrolein is very flammable its flash point is <0° C, but a toxic vapor cloud will develop before a flammable one. The flammable limits in air are 2.8% and 31.0% lower and upper explosive limits, respectively by volume. Acrolein is only partly soluble in water and will cause a floating fire, so alcohol type foam should be used in firefighting. The vapors are heavier than air and can travel along the ground and flash back from an ignition source. [Pg.128]

The next aldehyde is acetaldehyde, a colorless liquid with a pungent taste and a fruity odor. Its molecular formula is CH,CHO. It has a flash point of -40°F, an ignition temperature of 340°F, and is toxic by inhalation. Acetaldehyde is used in die manufacture of many other chemicals. Other important aldehydes are propionaldehyde, butyraldehyde, and acrolein. [Pg.169]

F) <0 OC -13 CC Flammable Limits in Air (%) 2.8 -31 Fire Extinguishing Agents Foam, dry chemical, carbon dioxide Fire Extinguishing Agents Not To Be Used Water may be ineffective Special Hazards of Combustion Products Poisonous vapor of acrolein is formed from hot liquid Behavior in Fire Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back. Polymerization may take place, and containers may explode in fire Ignition Temperature (deg. F) 453 Electrical Hazard Data not available Burning Rate 3.8 mm/min.

Acrolein (2-propenal, CH2=CHCHO, freezing point -87°C, boiling point 52.7°C, density 0.8427, flash point -18°C) is the simplest unsaturated aldehyde. The primary characteristic of acrolein is its high reactivity due to conjugation of the carbonyl group with a vinyl group. [Pg.23]

Smoke Point. As oils or fats are heated, a thin bluish smoke appears. The smoke point is the lowest temperature, under controlled conditions, that the smoke becomes visible. Cottonseed oil s smoke, fire, and flash points, like other fats and oils, are almost entirely dependent on the free fatty acid content. Fats and oils smoke point results decrease when the triglycerides are split during hydrolysis to form free fatty acids and glycerol. The glycerol portion decomposes to form acrolein, which is the major portion of the smoke evolved from heated fats and oils. Like other long-chain fatty acid oils, cottonseed oil with 0.01% free fatty acid will have a smoke point of approximately 450°F. Additions of monoglycerides... [Pg.840]

BUTANAMINE (109-73-9) C4H N Forms explosive mixture with air [explosion limits in air (vol %) 1.7 to 9.8 flash point 10°F/-12°C 594°F/312°C Fire Rating 3]. An organic base. Reacts, possibly violently, with oxidizers, acids, acrolein, maleic anhydride, nitrosyl perchlorate, perchloryl... [Pg.160]

CsHjoOj Combustible liquid. Forms explosive mixture with air [explosion limits in air (vol %) 1.6 to uel unknown flash point 149°F/65°C Fire Rating 1]. Unless inhibited (200 ppm hydroquinone recommended), polymerization may occur avoid exposure to high temperatures, ultraviolet light, free-radical initiators. Reacts with water with release of heat may not be violent if not contained. Strong oxidizers may cause fne and explosions. Reacts violently with sodium peroxide, uranium fluoride. Incompatible with strong acids, nitrates. Incompatible with sulfuric acid, nitric acid, caustics, aliphatic amines, isocyanates, boranes. Thermal decomposition releases toxic acrid fumes of acrolein and acrylic acid. On small fires, use dry chemical powder (such as Purple-K-Powder), water spray, alcohol-resistant foam, or CO2 extinguishers. [Pg.899]

ACROLEIN (107-02-8) Forms explosive mixture with air (flash point — I5°F/—26°C). Unstable and very reactive. In storage, over time, it can form heat- and shock-sensitive compounds or acids. Unless inhibited (usually by hydroquinone), readily forms explosive peroxides. May polymerize explosively, especially in elevated temperatures, on contact with oxidizers, strong acids, caustics, sunlight. A strong reducing agent. Reacts violently with amines, 2-aminoethanol, ammonia, ethylene diamine, ethyleneimine, hydroxides, metal salts. [Pg.37]
