Stable, but light-sensitive, sensitive to air. May contain BHT (2,6-di-tert-butyl-4-methylphenol) as a stabilizer. Substances to be avoided include zinc, halogens, halogen-halogen compounds, nonmetals, nonmetallic oxyhalides, strong oxidizing agents, chromyl chloride, turpentine oils, turps substitutes, nitrates, metallic chlorides.
Extremely flammable. This material is a serious fire and explosion risk. Vapour may travel considerable distances to ignition sources, which need not be an open flame, but may be a hot plate, steam pipe, etc. Vapour may be ignited by the static electricty which can build up when ether is being poured from one vessel into another. If large quantities of material are being poured, suitable precautions must be taken.
May form explosive peroxides on storage. Peroxides are generally higher-boiling than the materials from which they form. Consequently, if a peroxide-containing solution is heated, the residue becomes progressively more concentrated in peroxide and the risk of explosion increases rapidly. Vapour-air mixture explosive (note wide explosion limits). As at 6.11.97 regulated in the UK under the Highly Flammable Liquids and Liquefied Petroleum Gases Regulations 1972.
