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.

Efficient Reducing and Drying Agent

Calcium Hydride is well-regarded in laboratories and industries for its high efficacy as a reducing and drying agent. Its ability to remove moisture and participate in chemical reactions makes it indispensable for preparing anhydrous solvents and reducing metal oxides. This reactivity, combined with its stable nature under controlled conditions, ensures consistent performance.


Safe Handling and Storage Guidelines

Handling Calcium Hydride requires strict safety precautions due to its reactive and flammable nature, especially when in contact with water. Always use protective gloves and eye shields. Store this compound in a tightly closed HDPE container in a cool, dry environment to ensure safety and longevity. Adhering to these guidelines helps to maintain product quality and laboratory safety standards.
