SECTION 10: Stability and reactivity
Reactivity
Reacts with oxidants. Reacts with copper. This generates explosion hazard. Reacts violently with acids. Heating may cause violent combustion or explosion. Decomposes on contact with hot surfaces or flames. This produces irritating fumes.
Chemical stability
no data available
Possibility of hazardous reactions
The vapour mixes well with air, explosive mixtures are easily formed.2-METHYL-2-HYDROXY-3-BUTYNE is an alcohol. 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.
