RTECS ED2725000 Storage class 4.3 Hazardous materials, which set free flammable gases upon contact with water WGK WGK 2 water endangering Disposal 26 Alkali and alkaline-earth metals should be taken up in an inert solvent and neutralized by adding 2-propanol (Cat. No. 100995) dropwise with stirring. Should the reaction be more violent than expected, conversion should be carried out with tert-butanol or octanol. Caution: This reaction produces hydrogen, which can form explosive mixtures; take necessary precautions. When the reaction has ceased, add water dropwise; neutralize; container D. In the case of alkali or alkaline-earth borohydrides, add methanol (Cat. No. 106008) with stirring; in the case of alkali or alkaline-earth amides and hydrides, organoaluminium and organotin hydrides, add 2-propanol (Cat. No. 100995) dropwise. The substances, which are usually in solid form, should be previously suspended in an ether! When the respective reaction has ceased, hydrolize with water; then neutralize. Container D or E. Lithium aluminium hydride must also be destroyed by slurrying in an ether. Under an inert gas and with thorough stirring, add dropwise a 1:4 mixture of ethyl acetate (Cat. No. 822277) and the ether used to prepare the slurry. Always ensure thorough mixing (stirring)! Container A. Safety Information Hazard Symbols Corrosive Flammable Categories of danger highly flammable, corrosive R Phrase R 15-34 Contact with water liberates extremely flammable gases.Causes burns. S Phrase S 26-36/37/39-43-45 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice.Wear suitable protective clothing, gloves and eye/face protection.In case of fire, use sand. Never use water.In case of accident or if you feel unwell, seek medical advice immediately (show the label where possible). Storage and Shipping Information Storage Store below +30C.
