China’s MEK(methyl ethyl ketone) overview

In China, most of Butanone, also known as methyl ethyl ketone or MEK is produced by the dehydrogenation of 2-butanol using a catalyst based on copper, zinc, or bronze.

Production method of methyl ethyl ketone:

The reactions are as follows:

CH2CHCH2CH3 + H2O→CH3CH(OH)CH2CH3

CH3CH(OH)CH2CH3 → CH3C(O)CH2CH3 + H2

Applications:

–As a solvent

Butanone is an effective and common solvent and is used in processes involving gums, resins, cellulose acetate and nitrocellulose coatings and in vinyl films. For this reason it finds use in the manufacture of plastics, textiles, in the production of paraffin wax, and in household products such as lacquer, varnishes, paint remover, a denaturing agent for denatured alcohol, glues, and as a cleaning agent. It has similar solvent properties to acetone but boils at a higher temperature and has a significantly slower evaporation rate. Butanone is also used in dry erase markers as the solvent of the erasable dye.

–As a plastic welding agent

As butanone dissolves polystyrene, it is sold as “model cement” for use in connecting together parts of scale model kits. Though often considered an adhesive, it is actually functioning as a welding agent in this context.

–Other uses

Butanone is the precursor to methyl ethyl ketone peroxide, which is a catalyst for some polymerization reactions such as crosslinking of unsaturated polyester resins.
