2-ETHOXY-3,4-DIHYDRO-2H-PYRAN Chemical Properties,Usage,Production

Chemical Properties

Colorless transparent liquid

Uses

Stabilizer, intermediate.

Synthesis Reference(s)

The Journal of Organic Chemistry, 42, p. 282, 1977 DOI: 10.1021/jo00422a025

General Description

Colorless liquid. Floats on water.

Reactivity Profile

Ethers, such as 2-ETHOXY-3,4-DIHYDRO-2H-PYRAN 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.

Hazard

Moderate fire risk.

Health Hazard

Contact with liquid irritates eyes. Also irritates skin on prolonged contact.

Safety Profile

Moderately toxic by skin contact. Mildly toxic by ingestion and inhalation. A skin and eye irritant. Flammable liquid when exposed to flame, sparks, and oxidizers. To fight fire, use dry chemical, foam, fog. When heated to decomposition it emits acrid smoke and irritating fumes
