Common substances of epoxy compounds

1. Ethylene oxide
Also known as ethylene oxide, 1,2-ethylene oxide, dihydroethylene oxide. Flash point -28.9℃. Mixed with air to form explosive mixture. Contact with amines, ammonia, potassium, covalent hydrides to produce explosive polymerization reaction, the reaction is dangerous. Contact with highly active catalytic surfaces (anhydrous iron, tin, aluminum chloride, pure iron, aluminum oxide, sodium hydroxide) to produce violent chemical. Rearrangement or polymerization exothermic reaction. Small amounts of strong acids, alkali metals, and oxidants can also cause reactions. Avoid contact with copper, magnesium, mercury, silver and their alloys (including solder) to prevent the formation of explosive acetylated metals.
Prevent container damage, heat, and light. It can react in an insulator to form polyethylene glycol, which generates heat spontaneously and ignites at <100℃. It reacts violently with strong oxidants, alcohols, aluminum, amines, glycerol, nitrogen pentoxide, and m-nitroaniline; it is incompatible with ethyl bromide, magnesium perchlorate, mercaptans, salts, alkanethiols, and flammables. Low conductivity, static electricity will be generated when flowing or agitating. Attacks some rubber, plastic and cotton fabrics.
2. Propylene oxide
Also known as propylene oxide, methyl ethylene oxide, 1,2-propylene oxide, 2,3-propylene oxide. Flash point -37.0℃. Mixed with air or oxygen to form explosive mixture. Dangerous polymerization occurs with acids, caustic alkalis, and perhalides; reacts with water and water vapor to form unstable peroxides. Reacts with acids, ammonia, amines, acetylated metals, and clay-based absorbents; incompatible with anhydrous metal chlorides, ammonium hydroxide, and salts. Low conductivity, static electricity will be generated when flowing or agitating, and its vapor may ignite. Attacks some rubber, plastic and cotton fabrics.
