Abstract: Disclosed is a method of separating NaCl from a NaCl contaminated aqueous LiCl solution involving concentration of the solution, cooling of concentrated solution and separation of the crystallized NaCl. The method is characterized in that the concentration and cooling or cooling of the solution are carried out in the presence of a base, preferably in the presence of 0.3-5 wt % (related to LiCl) of at least one alkaline or alkaline earth hydroxide or at least one easily soluble and difficultly volatile amine.

Abstract: A process is disclosed for the preparation of tertiary alcohols, alpha-alkyl substituted nitriles, alkyl-substituted imines or tertiary amines by alkylation of a starting material that is a carbonyl compound or a nitrile followed by hydrolysis wherein the alkylation is carried out with the aid of a reaction system formed by suspending a mixture of:substantially 15 to 25% by weight of methyllithium or ethyllithium;substantially 35 to 45% by weight of an inorganic compound selected from the group which consists of at least one metal oxide selected from the group which consists of SiO.sub.2, Al.sub.2 O.sub.3, and CaO, and synthetic anhydrous aluminum silicate; andsubstantially 35 to 45% by weight of a paraffin oil or wax; in an organic solvent selected from the group which consists of:C.sub.5 to C.sub.10 saturated aliphatic hydrocarbons, C.sub.5 to C.sub.

Abstract: A composition for use in synthesis reactions comprises a mixture of an organolithium compound and an inert inorganic pulverulent carrier and consists of methyllithium and ethyllithium, one or more of the group consisting of SiO.sub.2, Al.sub.2 O.sub.3, CaO and synthetic anhydrous aluminosilicate, and paraffin. That composition is flowable and non-pyrophoric.
