| 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. |
