What is 2-PROPOXYETHANOL?

Chemical properties

oily colourless odourless liquid

What are the applications of Application

Ethylene glycol monopropyl ether is A solvent based on alkyl ether

General Description

Liquid; colorless; mild, rancid odor; floats and mixes with water.

Air & Water Reactions

Ethers tend to form unstable peroxides when exposed to oxygen. Ethyl, isobutyl, ethyl tert-butyl, and ethyl tert-pentyl ether are particularly hazardous in this respect. Ether peroxides can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid.

Reactivity Profile

Ethers, such as 2-PROPOXYETHANOL can act as bases. They form salts with strong acids and addition complexes with Lewis acids. The complex between diethyl ether and boron trifluoride is an example. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.

Health Hazard

VAPOR: Irritating eyes and nose. LIQUID: Can cause corneal damage. INHALATION: Can cause toxic effects. SKIN: Contact can cause toxic effects.

Fire Hazard

Combustible: Carbon dioxide and carbon monoxide may be produced in a fire.

Safety Profile

Moderately toxic by ingestion and skin contact. Mildly toxic by inhalation. An experimental teratogen. Experimental reproductive effects. Some glycol ethers have dangerous human reproductive effects. A skin and severe eye irritant. Flammable; can react with oxilzing materials. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
