Butyl alcohol flash point

Butyl alcohol (melting point 25.8°C, boiling point 82.4°C, density 0.7866, flash point 11.1°C) is a low-melting solid that, after melting, exists as a colorless liquid. 

MEK is used in a variety of ways as a solvent. It owes part of its popularity to the fact that it is a low boiling point replacement for the butyl alcohols in vinyl, nitrocellulose, acrylic, and other coatings. In these applications, MEK flashes (vaporizes or dries ) quickly at ambient temperatures, leaving the coating behind. However, MEK is classified as a hazardous material, putting special requirements on where and how it can be used. 

The above-mentioned alcohols are by far the most common. Butyl alcohol is not as commonly used as die first four in die series, but it is used. Secondary butyl alcohol and tertiary butyl alcohol, so named because of the type of carbon atom in the molecule to which the hydroxyl radical is attached, must be mentioned because they are flammable liquids, while isobutyl alcohol has a flash point of 100°F. All of the alcohols of the first four carbon atoms in the alkanes, therefore, are extremely hazardous because of their combustion characteristics. 

Methyl ethyl ketone (MEK boiling point 769.6°C, density 0.8062, flash point -6°C) is an important coating solvent for many polymers and is made by the sulfation and hydration of 1 or 2-butene to sec-butyl alcohol, which is then dehydrogenated to the ketone (Fig. 1).
