Butanone (CAS 78-93-3) is also known as methyl ethyl ketone or MEK. It is a colourless, flammable liquid with a sweet acetone-like odour. Butanone is used in paints, glues and finishes because it quickly evaporates in air and will dissolve in many substances. The major uses of butanone are: solvent in application of protective coatings...

Fluorine (as F2) (CAS 7782-41-4) is a pale yellow gas at normal temperature with an odour similar to ozone. It is extremely reactive; organic and hydrogen-containing compounds may burn or explode when exposed to it. Due to its reactivity, fluorine gas rarely occurs in nature, with fluoride ion more commonly found. The major occupational...
