What is the density of MEK?
805 kg/m³
Butanone/Density
Does MEK evaporate?
It is also known as methyl ethyl ketone (MEK). 2-Butanone is produced in large quantities. Nearly half of its use is in paints and other coatings because it will quickly evaporate into the air and it dissolves many substances.
Does MEK mix with water?
Unlike Acetone, MEK forms an azeotrope with water, which means that methyl ethyl ketone and water mix together to form a constant boiling point that cannot be affected by distillation. MEK is both less soluble and less volatile than acetone.
Is MEK soluble in water?
Alcohol
Water
Butanone/Soluble in
Is MEK polar?
Hexane, tetrahydrofuran and methylene chloride are non-polar solvents. Polar solvents are hydrophilic but non-polar solvents are lipophilic. Polar reactants will dissolve in polar solvents….METHYL ETHYL KETONE.

Does MEK float on water?
Methyl ethyl ketone is a flammable liquid. It is partially soluble in water, and soluble in most other organic solvents. It will float on water while it rapidly dissolves in it.
Is MEK polar or nonpolar?
Since the major composition of the sludge consisted of non-polar components, therefore, non-polar solvent (MEK) shows better efficiency. The optimum conditions of the studies were 20 °C, 19 min, and 6.4/4.2 for MEK and 55 °C, 17 min, and 3.6/3.6 for toluene.
Is MEK banned in USA?
MEK is a popular chemical solvent used across several industries including ink, varnishes, and paint, but has MEK been banned? The answer is no. In fact, MEK is even approved by the FDA for indirect food processes, such as use as an additive for adhesives and polymers.
Why is MEK used?
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 will MEK dissolve?
MEK is used as an effective plastic welding agent. It can dissolve many plastics, including polystyrene, and can bind plastics together. MEK works as a welding agent by dissolving the surface where it is applied and then evaporating – acting as more of a chemical welding agent.
What is the chemical formula for MEK?
It is stable in that it does not react with water. But it reacts with strong oxidizing agents. It is not corrosive to metal, but softens some plastics. The molecular formula for MEK may be written as either (CH 3) 2 CH 2 CO or, more commonly, CH 3 COCH 2 CH 3.
What are the side effects of MEK vapors?
Its odor may be detected at levels between 10 and 15 ppm. Contact of MEK vapors with the eyes, nose, and throat produces irritation in these organs. Contact of the liquid with the eyes causes irritation and possible permanent damage. Contact of the liquid with skin causes irritation by defatting.
What are the physical properties of memek?
MEK is irritating, volatile, and somewhat pungent. Its flash point is 16°F, attesting to its flammability. The solvent’s ignition temperature is 759°F, and its flammable range is from 1.4% to 11.5% in air. It has a specific gravity of 0.806, a molecular weight of 72, and a vapor density of 2.49.
What are the side effects of methyl ethyl ketone (MEK)?
Acute Effects: Acute exposure of humans to high concentrations of methyl ethyl ketone produces irritation to the eyes, nose, and throat. (1,4) Other effects reported from acute inhalation exposure in humans include central nervous system depression, headache, and nausea.
