Acetone ignition temperature

Acetone cyanohydrin (Oxyisobutyric nitrile) (CH3)2C(0H)CN Highly toxic by inhalation or ingestion Irritating and moderately toxic upon skin contact Readily decomposes to HCN and acetone at 1 20°C, or at lower temperatures when exposed to alkaline conditions Colourless combustible liquid Elash point 73°C Ignition temperature 68.7°C Completely soluble in water... 

The next most common ketone is methyl ethyl ketone, commonly referred to as MEK. Its molecular formula is CH3COC2H5. MEK has a flash point of 24°F and an ignition temperature of 960" F. It is a colorless liquid with a characteristic ketone odor. It is as widely used as acetone and is almost as hazardous. 

Acetone. Ignition occurs on contact at room temperature thus, the trioxide should not be used to purify acetone.10... 

Toluene is a notoriously poor electrical conductor even in grounded equipment it has caused several fires and explosions from static electricity. Near normal room temperature it has a concentration that is one of the easiest to ignite and, as previously discussed, that generates maximum explosion effects when ignited (Bodurtha, 1980, p. 39). Methyl alcohol has similar characteristics, but it is less prone to ignition by static electricity because it is a good conductor. Acetone is also a good conductor, but it has an equihbrium vapor pressure near normal room temperature, well above UFL. Thus, acetone is not flammable in these circumstances. 

The use of chromium trioxide to purify acetone is hazardous, ignition on contact occurring at ambient temperature. Methanol behaves similarly when used to reduce the trioxide in preparing hexaaquachromium(III) sulfate.
