A process for the recovery of lithium from waste lithium ion batteries or parts thereof is disclosed. The process comprising the steps of A) providing a crude lithium hydroxide as a solid, which contains fluoride; and (B) dissolving the crude lithium hydroxide solid with a lower alcohol such as methanol or ethanol provides good separation of lithium in high purity.

Process for the purification of lithium salts

The present invention relates to a process for producing menthol particles stabilized against caking, wherein menthol particles are, following shaping, stored for at least 7 days at a temperature of 0 to 30° C., after which the menthol particles are supplied with a minimum input of mechanical energy. The present invention further relates to storage-stable menthol particles and to the use of said menthol particles in household and consumer goods of all kinds.

The present invention relates to a process for enriching enantiomers from an enantiomer mixture by a fractionating melt crystallization in a melt crystallization apparatus. The invention specifically relates to a process for producing an enantiomer-enriched chiral terpene, in particular of D/L-Isopulegol. The process comprises:

Process for enriching enantiomers from an enantiomer mixture

The present invention relates to a method for separating off a substance from a solution, in which electromagnetic radiation is radiated into the solution, an intensity of the electromagnetic radiation which has been scattered by crystals located in the solution is detected, the detected intensity is compared with a desired intensity (I) and the temperature of the solution is regulated depending on the difference between the detected intensity and the desired intensity (I) in such a way that the amount of this difference is reduced. If the amount of the difference between the detected intensity and the desired intensity (I) is less than a limiting value, a crystallization method is started in which crystals of the substance are obtained which are then separated off.

Method and device for separating a substance out of a solution

The present invention relates to a particularly economic overall method for producing menthol, specifically for producing optically active, essentially enantiomerically and diastereomerically pure L-menthol and racemic menthol, starting from the starting material citral which is available inexpensively on an industrial scale. The method has the following steps
