Use

Butyl alcohols may form explosive mixture with air. In all cases they are Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Attacks some plastics, rubber and coatings. n-Butanol is incompatible with strong acids; halogens, caustics, alkali metals; aliphatic amines; isocyanates. sec-Butanol forms an explosive peroxide in air. Ignites with chromium trioxide. Incompatible with strong oxidizers; strong acids; aliphatic amines; isocyanates, organic peroxides. tert-Butanol is incompatible with strong acids (including mineral acid), including mineral acids; strong oxidizers or caustics, aliphatic amines; isocyanates, alkali metals (i.e., lithium, sodium, potassium, rubidium, cesium, francium). isoButanol is incompatible with strong acids; strong oxidizers; caustics, aliphatic amines; isocyanates, alkali metals and alkali earth. May react with aluminum at high temperatur
