Abstract: Disclosed herein is a process for making a particulate (oxy)hydroxide of TM, where TM represents a combination of metals and includes nickel and at least one metal selected from cobalt and aluminum and manganese. The process includes: (a) combining an aqueous slurry of metallic nickel and at least one metal selected from aluminum and transition metals other than nickel with an oxidant selected from oxygen and nitrate in a first reaction vessel or in a first group of reaction vessels at a temperature of from 5° to 40° C., (b) transferring aqueous reaction medium from the first reaction vessel to a second reaction vessel, where the second reaction vessel contains a slurry of a hydroxide of TM, (c) removing the particles from step (b) from the liquid by a solid-liquid separation method, and drying the particles, and (d) returning liquid phase obtained in step (c) to the first reaction vessel.

Abstract: Disclosed herein is a process for making a particulate (oxy)hydroxide of TM, where TM represents metals and includes nickel and at least one metal selected from cobalt and aluminum and manganese. The process includes the steps of:
(a) combining an aqueous slurry of metallic nickel and at least one metal selected from cobalt and manganese and aluminum with an oxidant selected from nitrate and peroxide in a reaction vessel under an atmosphere with less than 100 ppm O2, thereby obtaining an aqueous reaction medium with a pH value in the range of from 7.5 to 12 containing particles,
(b) removing the particles from step (a) from the liquid by a solid-liquid separation method, and drying the particles, and
(c) returning mother liquor obtained in step (b) to the reaction vessel.-

Abstract: 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: i) a crystallization step to obtain a crystallizate and a mother melt and removal of the mother melt from the crystallizate to afford a mother melt fraction; ii) sweating of the crystallizate obtained in step i) to afford a molten sweating fraction and iii) subsequent melting of the sweated crystallizate to afford a molten crystallizate fraction, wherein the optical rotation at least of the sweating fraction is determined online using a polarimeter and the changeover from step ii) to step iii) is controlled online by means of at least one control unit.

Abstract: 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 (IS) and the temperature of the solution is regulated depending on the difference between the detected intensity and the desired intensity (IS) 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 (IS) is less than a limiting value, a crystallization method is started in which crystals of the substance are obtained which are then separated off.
