    Abstract: The instant invention relates to a method for purifying lactams wherein the lactam to be purified is contacted in the fused state with inorganic adsorption agents.The said method comprises contacting the lactam to be purified in the fused state with an inorganic adsorbent, then separating the lactam from the adsorbent and regenerating said adsorbent if desired, wherein said adsorbent is impregnated with at least one impregnation compound selected from the group consisting of an acid and the alkali metal salts which are thermally stable and exert no action on the lactam at temperatures lower tha 250.degree.C.

    Abstract: A process for the preparation of a pulverulent organomagnesium compound involves bringing together into intimate admixture a particulate hydroxyl functional material with an organomagnesium-containing material. The process is conducted at a temperature below the melting point of the hydroxyl functional material but at a temperature sufficient to convert at least a portion of the hydroxyl functional material to the pulverulent organomagnesium compound. The aforesaid organomagnesium compounds are useful as intermediates in generating anionic sites for anionic polymerization.
