butanone

1, Nature: also known as methyl ethyl ketone, butanone, a methyl ethyl ketone. Colorless, volatile liquid easily. A similar smell of acetone. With ethanol, ethyl ether phase immiscibility. -6 ℃ boiling point flash point of 79.64 ℃. The relative density: 0.8054. Refractive index of 1.3788, 1.3764. Vapour pressure (25 ℃) 12 kPa. For a flammable liquid. Strong toxic than acetone, a narcotic, central nervous system can function decline. The non-corrosive metal, available iron, mild steel, copper or aluminum containers for the storage. 
2, from butene to nickel or zinc oxide as a catalyst and generate 2-butanol hydrated sulfate, and under normal pressure system in the dehydrogenation. 
3, use: commonly used for various polymers, such as nitrocellulose, cellulose acetate, vinyl, acrylic, alkyd, phenolic resin and paint, ink and dye solvent bonding agent, also used for Detergents, lubricants dewaxing agents, curing agents and promote the reaction intermediates, and so on. Chemical solvents and lubricants for the dewaxing agent. 
4, packaging: iron packaging, according to flammable toxic chemicals storage requirements.
