2-Hexanone

2-Hexanone (methyl butyl ketone, MBK) is a ketone used as a general solvent and in paints.

It dissolves cellulose nitrate, vinyl polymers and copolymers, and natural and synthetic resins.

It is recommended as a solvent because it is photochemically inactive;[5] however it has a very low safe threshold limit value.

2-Hexanone is absorbed through the lungs, orally and dermally and its metabolite, 2,5-hexanedione, is neurotoxic.

[6] Animal tests have shown that the neurotoxic effect of 2-hexanone may be potentiated by simultaneous administration of 2-butanone (methyl ethyl ketone, MEK).

E.g. chloroform Flammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g. gasoline Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
