CA 2166770

A high temperature process for producing alkyllithium compounds in high yields of at least 90 % and high purity comprising reacting, in a liquid hydrocarbon solvent, an alkyl halide containing 3 to 16 carbon atoms and mixtures thereof with lithium metal particles of less than 300 microns in size at a temperature between 35 and 125 °C and recovering the alkyllithium compound.

Procédé d'obtention à hautes températures de composés d'alkyllithium d'une grande pureté avec un rendement élevé d'au moins 90 %, consistant à faire réagir, dans un hydrocarbure liquide (comme solvant), un halogénure d'alkyle à 3 à 16 atomes de carbone et des mélanges de celui-ci avec des particules de lithium de moins de 300 mu à une température comprise entre 35 et 125 DEG C et à recueillir les composés d'alkyllithium.
