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.

How much does a 55 gallon drum of MEK weigh?

406 lbs
It appears as a colorless liquid with a slight odor….Additional information.

Weight 406 lbs

Is MEK chlorinated?

Methyl ethyl ketone does not contain detectable quantities of polycyclic aromatics, heavy metals or chlorinated compounds. For detailed Hazard Information please refer to the Safety Data Sheet on ww.shell.com/chemicals.

What is the density of methyl isobutyl ketone?

802 kg/m³Methyl isobutyl ketone / Density

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.

How explosive is MEK?

METHYL ETHYL KETONE is explosive in the form of vapor when exposed to heat, flame or sparks. Ignition on contact with potassium tert-butoxide. Reactive with strong oxidizing materials, and will dissolve or soften some plastics. Mixture with 2-propanol will form explosive peroxides during storage.

Will MEK dissolve plastic?

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.

Is methyl isobutyl ketone?

Methyl isobutyl ketone (MIBK) is the common name for the organic compound 4-methylpentan-2-one, condensed chemical formula (CH3)2CHCH2C(O)CH3. This colourless liquid, a ketone, is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.

What is methyl isobutyl ketone used for?

Methyl isobutyl ketone is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose. Acute (short-term) exposure to methyl isobutyl ketone may irritate the eyes and mucous membranes, and cause weakness, headache, nausea, lightheadedness, vomiting, dizziness, incoordination, narcosis in humans.

What is MEK VOC?

MEK is still regulated as a VOC. Methyl acetate has a lower chemical reactivity in the air environment and is considered VOC-exempt. When disposed of, MEK must be treated as a hazardous waste and is also a TRI listed chemical. Methyl acetate is not regulated as a hazardous waste.
