MESITYL OXIDE Chemical Properties,Uses,Production

Description

Mesity oxide is a tri-functional intermediate of considerable utility in the synthesis of a number of different types of organic compounds, such as mesityl oxide can be hydrogenated to methyl isobutyl ketone and other flavor ingredients in foods, such as 4- methyl-pentanone. Mesityl oxide can be used as a solvent for resins, gums, nitrocellulose, oils, lacquers, and inks. It is also used as an insect repellant and used in ore flotation.

Chemical Properties

CLEAR LIGHT YELLOW LIQUID

General Description

A colorless, oily liquid with a pungent honey-like odor. Flash point 87°F. Less dense than water and slightly soluble in water. Vapors heavier than air. Used in paint removers, as a solvent for plastics, and as an insect repellent.

Air & Water Reactions

Highly flammable. Slightly soluble in water

Reactivity Profile

Mixing MESITYL OXIDE in equal molar proportions with any of the following substances in a closed container caused the temperature and pressure to increase: 2-aminoethanol, chlorosulfonic acid, ethylene diamine, nitric acid, oleum, or sulfuric acid [NFPA 1991].

Health Hazard

Inhalation causes irritation of nose and throat, headache, dizziness, difficult breathing. Contact with liquid or concentrated vapor causes severe eye irritation. Liquid irritates skin. Ingestion causes irritation of mouth and stomach.

Fire Hazard

Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.
