Fire Hazards
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]:
· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.
Health Hazards
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]:
· May cause toxic effects if inhaled or absorbed through skin.
Hazards Summary
A mild skin and moderate eye irritant; Dermal LD50 (rabbit) = 20 mL/kg; [RTECS] Not a skin sensitizer in guinea pig maximization study; No sensitization reactions observed in maximization test of 26 volunteers at 4% in petrolatum; [IUCLID] Safe when used as a flavoring agent in food; [EFSA] A mild skin irritant; [Sigma-Aldrich MSDS] See 1,1-Dimethoxyethane.
Reactivity Profile
ETHYL ORTHOFORMATE is an ether. Ethers 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.
