Reactive Group:

Alcohols and Polyols

Reactivity Alerts:

Highly Flammable

Reactivity Profile:

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.

Autoignition Temperature:

350 °C

Physical Dangers:

The vapour mixes well with air, explosive mixtures are easily formed.
