Abstract: The invention relates to a method for producing highly pure LiBF4 by preparing a solution of BF3 etherate in diethyl ether, suspending LiF in this solution, converting same into solid LiBF4 and then separating the resulting solid LiBF4. The invention also relates to the use of LiBF4 obtained in this manner for the production of lithium-ion batteries.

Abstract: A process for the preparation of racemic amines of the formula I where R1 and R2 are different and R1, R2, R3 are alkyl, cycloalkyl, arylalkyl, aryl, heteroaryl and heterocyclic radicals and R3 can also be hydrogen, where the radicals can bear substituents selected from the group consisting of alkyl, cycloalkyl, alkoxy, aryloxy, amino, alkylamino and dialkylamino, which comprises simultaneously reacting in situ the corresponding optically active amine I and the secondary alcohol of the formula II and/or the unsymmetrical ketone of the formula III and the amine of the formula R3NH2 in the presence of hydrogen and a hydrogenation catalyst or dehydrogenation catalyst at elevated temperature.

Abstract: The invention relates to a method for producing racemic amines of formula (I ), in which R1 and R2 are not the same and R1, R2, R3 are alkyl-, cycloalkyl-, arylalkyl-, aryl-, heteroaryl rests and heterocyclic rests and R3 also represents hydrogen. Said rests can carry substituents selected from the group of alkyl, cycloalkyl, alkoxy, aryloxy, amino, alkylamino and dialkylamino. The method is characterized in that the corresponding optically active amine (I) and the secondary alcoh ol of formula (II) and/or the asymmetrical ketone of formula (III) and the amine of the formula R3NH2 are simultaneously reacted in situ in the presence of hydrogen and a hydrogenation or dehydrogenation catalyst at an elevated temperature.
