Is methyl ethyl ketoxime toxic?

Is methyl ethyl ketoxime toxic?

MEKO is moderately toxic in the unlikely event of ingestion. Ingesting or breathing high concentrations may cause harmful, but reversible, effects on the blood (anemia) and inhalation can irritate nasal passages.

Is methyl ethyl ketone toxic?

It can be harmful to the eyes, skin, and if inhaled or swallowed. Workers may be harmed from exposure to methyl ethyl ketone. The level of exposure depends upon the dose, duration, and work being done. Methyl ethyl ketone is used in many industries.

Is methyl ethyl ketone banned in the US?

The answer is no. MEK, while it can be hazardous when not used properly, is not considered to present a considerable enough threat to the user or the environment for the EPA to ban the use of this chemical.

Is methyl ethyl ketone cancerous?

EPA has classified methyl ethyl ketone as a Group D, not classifiable as to human carcinogenicity.

Is methyl ethyl ketoxime a VOC?

A stricter classification of this material would result in its withdrawal from the alkyd based paint and lacquer market. Meanwhile it is a volatile organic compound, which means it will not stay in the final product after its surface dries, however its stricter classification would eliminate its use.

Is methyl ethyl ketone harmful to the environment?

Methyl ethyl ketone by itself is not likely to cause environmental harm at levels normally found in the envi- ronment. MEK can contribute to the formation of photochemical smog when it reacts with other volatile organic carbon substances in air.

Is methyl ethyl ketone peroxide toxic?

Methyl Ethyl Ketone Peroxide (MEKP) is a highly toxic clear liquid used as a solvent. It is a strong oxidizing agent and a corrosive. Acute and chronic toxicity can occur as an occupational hazard.

Is methyl ethyl ketone a VOC?

some chemical compounds are regulated as volatile organic compounds (VOCs) and others are not. At first glance it may appear that the U.S. EPA randomly favors certain products, while others, such as toluene, xylene, and methyl ethyl ketone (MEK), are being regulated out of existence.

What is methyl ethyl ketone peroxide used for?

Methyl Ethyl Ketone Peroxide is a colorless to yellow liquid with a fragrant, mint-like odor. It is used in making plastic monomers, as a curing agent in polyester resins, and as a cross-linking agent and catalyst in making polymers.

Is methyl ethyl ketoxime toxic to animals?

The developmental toxicity of methyl ethyl ketoxime (MEKO), an industrial antioxidant used primarily as an antiskinning agent in alkyd paint, was investigated in rats and rabbits.

What is the hematology data for methyl ethyl ketoxime (met)?

Methyl Ethyl Ketoxime, NTP TOX 51 29 The hematology data for rats are listed in Tables 5 and B1. On day 5, exposure concentration-dependent increases of methemoglobin concentration, indicating oxidative red cell injury, occurred in 2,500 and 5,000 ppm male and female rats.

What is methyl ethyl ketoxime used for?

Methyl ethyl ketoxime is used primarily as an antiskinning agent in alkyd coating resins. Methyl ethyl ketoxime was selected for study because of the potential for human exposure and because of interest in oximes as a chemical class.

Does methyl ethyl ketoxime react with hydoxylamine?

In the metabolism study of methyl ethyl ketoxime in F344 rats, results indicate that the oxime is metabolized to the ketone and, presumably, hydoxylamine (RTI, 1991). The ketone was recovered in the volatiles after gavage administration; the ketone was also present in urine following gavage administration.
