Air and Water Reactions:Reacts exothermically with water to form memtetrahydrophthalic acid.
Reactive Group:Hydrocarbons, Aliphatic Unsaturated
Reactivity Alerts:Water-Reactive
Reactivity Profile:MEMTETRAHYDROPHTHALIC ANHYDRIDE is combustible. Reacts with oxidizers. Reacts exothermically with water. These reactions are usually slow, but can become violent when local heating accelerates their rate. Acids accelerate the reaction with water. Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.
Autoignition Temperature:450 °C
