04 · Handling and storage
Storing and handling 2-Ethyl-1-butanol
Reactivity
Flammable and/or toxic gases are generated by the combination of alcohols, such as 2-ETHYLBUTANOL, with alkali metals, nitrides, and strong reducing agents. Alcohols 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.
