Abstract:
Process for the manufacture and recovery of alkali-metal tetraorganylborates. A mixed solvent and liquid/liquid contactor configuration is used in the system which aids in the recovery of the product.
A method of effectively increasing the settling rate of solid co-products from relatively viscous dialkyl magnesium solutions and thereby reducing the viscosity of such solutions wherein a small quantity of bis(cyclopentadienyl)magnesium or other cyclopentadienyl compound is added thereto. Alternatively, the bis(cyclopentadienyl)magnesium may be prepared in situ by adding cyclopentadiene directly to the dialkyl magnesium.
A process for the preparation of alkali metal aluminum hydrides including reacting aluminum and an alkali metal or alkali metal hydride with hydrogen at elevated temperatures and under super atmospheric pressure in the presence of an aliphatic or aromatic hydrocarbon.
