Molecule Structure Image



Butanone is an organic compound. It 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 is also used in dry erase markers as the solvent of the erasable dye. As butanone melts polystyrene, it is sold as "polystyrene 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. It is the precursor to methyl ethyl ketone peroxide, a catalyst for some polymerization reactions.
