Storing and handling Hexan-1-ol

Storage conditions

Protect containers against physical damage. Keep containers closed and store in well-ventilated, cool place.

Incompatible materials

Can react with oxidizing materials.

Reactivity

HEXANOLS are alcohols. 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.
