MEK is a commonly used industrial solvent. Because methyl ethyl ketone is such a highly effective solvent, it is a common ingredient in processing resins, coatings, and mixtures; as well as manufacturing plastics, inks, and dyes.
Why is MEK a good solvent?
MEK or Methyl Ethyl Ketone is stronger than Acetone, because it has a slower evaporation rate and boils at a higher temperature. These differences are why MEK can be a stronger cleaning agent than acetone.
Is MEK an aromatic solvent?
Butanone, also known as methyl ethyl ketone (MEK), is an organic compound with the formula CH3C(O)CH2CH3. This colourless liquid ketone has a sharp, sweet odor reminiscent of acetone. It is produced industrially on a large scale, but occurs in nature only in trace amounts….Butanone.

How do you clean Methyl Ethyl Ketone?
* On skin contact with Methyl Ethyl Ketone, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted Methyl Ethyl Ketone, whether or not known skin contact has occurred.
What is solvent ketone?
Ketones are chemically stable solvents with the ability to dissolve a wide range of synthetic and natural resins, making them well suited to low viscosity and high solids formulations.
What does methyl ethyl ketone do?
Methyl ethyl ketone is used in many industries. It is used as a solvent and in the manufacture of synthetic rubber, paraffin wax, and to make other chemical products. Some examples of workers at risk of being exposed to methyl ethyl ketone include the following: Workers who work in printing plants.
What is methyl ethyl ketone MEK used for?
Methyl ethyl ketone (MEK) is a colorless liquid that has a sweet odor and is soluble in water. It is a highly volatile chemical and is frequently used as a commercial cleaner and solvent for glues, paints, coatings, and printing inks.
What is a ketone solvent?
What is MEK methyl ethyl ketone?
Also Known As “Mek” Or “Butanone” Methyl Ethyl Ketone (MEK) is a liquid solvent used in surface coatings, adhesives, printing inks, chemical intermediates, magnetic tapes and lube oil dewaxing agents.
Is methyl ethyl ketone soluble in water?

Why is MEK banned?
On March 30, 1998, EPA denied the petition based on the conclusion that Volatile Organic Compounds (VOCs), such as MEK, contribute to the formation of tropospheric ozone which is known to cause significant adverse effects to human health and the environment.
What is methyl amyl ketone used for?
MEK, MAK, and MIBK are used primarily as solvents in the manufacture of a wide variety of consumer products and as chemical intermediates, such adhesives, magnetic tapes, printing inks, de-greasing and cleaning fluids, antioxidants, perfumes, lacquers paint removers, cleaning fluids, acrylic coatings, pharmaceuticals.
What is the reaction between benzaldehyde and methyl ethyl ketone?
200 gms of Benzaldehyde and 300 gms of Methyl Ethyl Ketone are mixed in a 1 litre beaker and cooled below 5°C. HCl gas is bubbled through until 40gms has been added. The mixture goes from a clear solution to a red colour and becomes turbid so that you can’t see through it. The mixture is kept over night and becomes a brown colour.
Where does methyl ethyl ketone come from?
It is made by some trees and found in some fruits and vegetables in small amounts. It is also released to the air from car and truck exhausts. Methyl ethyl ketone is used as a solvent. Acute (short-term) inhalation exposure to methyl ethyl ketone in humans results in irritation to the eyes, nose, and throat.
What is the solubility of methyl ethyl ketone in boiling water?
Constant boiling mixture with water, BP 73.4 °C, contains 88.7% methyl ethyl ketone (MEK); Solubility of water in MEK is 12.5% at 25 °C O’Neil, M.J. (ed.). The Merck Index – An Encyclopedia of Chemicals, Drugs, and Biologicals.
How do you convert benzaldehyde to 2-acetoxy-1-phenyl 1-propene?
The first step is an acid catalyzed aldol condensation between benzaldehyde 1 and MEK 2 which forms 3-methyl-4-phenyl-3-buten-2-one 3. The second step is the Baeyer–Villiger oxidation which forms 2-acetoxy-1-phenyl-1-propene 4 from the reaction between 3-methyl-4-phenyl-3-buten-2-one 3 and peracetic acid (PAA).
