SECTION 10: Stability and reactivity
Reactivity
Reacts violently with oxidants oxidants.
Chemical stability
no data available
Possibility of hazardous reactions
The vapour mixes well with air, explosive mixtures are easily formed.An unsaturated aliphatic/alcohol. The unsaturated aliphatic hydrocarbons are generally much more reactive than the alkanes, which are saturated aliphatic hydrocarbons. Strong oxidizers may react vigorously with them. Reducing agents can react exothermically to release gaseous hydrogen. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert them to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
