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 made from?
MEK is a colorless organic liquid with an acetone-like odor. In the U.S., MEK is produced using dehydrogenation of secondary butyl alcohol (approximately 86%) and as a by- product of butane oxidation (remaining 14%).
What does butanone look like?
Butanone, also known as ethyl methyl ketone, 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.
Is methyl isobutyl ketone safe?
* Exposure to high concentrations can cause you to feel dizzy and lightheaded, and to pass out. * Prolonged contact can cause a skin rash, dryness and redness. * Methyl Isobutyl Ketone may damage the liver and kidneys. * Methyl Isobutyl Ketone is a FLAMMABLE LIQUID and a FIRE HAZARD.
Is methyl isobutyl ketone an alcohol?

Is MIBK soluble in water?
Solvent and niche applications Unlike the other common ketone solvents, acetone and MEK, MIBK has quite low solubility in water, making it useful for liquid-liquid extraction. It has a similar polarity to ethyl acetate, but greater stability towards aqueous acid and base.
Does MEK dissolve in water?
Can butanone be oxidized?
Main difference of butanal and butanone is, butanal can be oxidized by oxidizing agents. But, butanone cannot be oxidized like butanal.
Can ketones be oxidized?
Because ketones do not have hydrogen atom attached to their carbonyl, they are resistant to oxidation. Only very strong oxidizing agents such as potassium manganate(VII) (potassium permanganate) solution oxidize ketones.

Is dimethyl benzyl ammonium chloride bad to eat?
From the foregoing data it appears that hand- washed eating and drinking utensils may be effectively sanitized by rinsing them in a solution containing alkyl-dimethyl-benzyl-ammonium-chloride in a concentration of 1 :5000 parts of water. The concentrations of this product do not seem to be greatly affected by the addition of organic matter.
Would cyclohexanone be a methyl ketone?
Methyl Ethyl Ketone. MEK is suggested over the 80:20 blend of methylene chloride in cyclohexanone due to the possibility of crazing caused by high amounts of methylene chloride.
What does dimethyl mean?
Dimethylglycine is an amino acid, a building block for protein. It is found in the body in very small amounts and for only seconds at a time.
