The main component of the cleaning agent used in the general ink of the printer is butanone (also known as methyl ethyl ketone) or acetone, and alcohol is also used. Butanone and acetone are chemically similar. Butanone: a colorless liquid. Melting point - 86.3 ° C, boiling point 79.6 ° C, relative density 0.8054 (20 / 4 ° C ) . It is soluble in about 4 times of water and can be dissolved in organic solvents such as ethanol and ***. It forms a constant boiling point mixture with water ( containing 88.7 % of methyl ethyl ketone ) and has a boiling point of 73.4 °C. Steam and air can form an explosive mixture with an explosion limit of 2.0 % to 12.0 % by volume.
The chemical properties are similar to those of acetone. Butanone is an important component of the distillate (wood alcohol oil) of dry distillation wood. It can be industrially dehydrogenated with secondary butanol or produced by water addition oxidation with butene. Butanone is an important solvent for paints, and nitrocellulose and synthetic resins are easily soluble in them.
