Abstract: The present disclosure is in the field of processes for the generation of thin inorganic films on substrates, in particular atomic layer deposition processes. Described herein is a process for preparing metal-containing films including: (a) depositing a metal-containing compound from the gaseous state onto a solid substrate, and (b) bringing the solid substrate with the deposited metal-containing compound in contact with a compound of general formula (I) wherein Z is a C2-C4 alkylene group, and R is hydrogen, an alkyl group, an alkenyl group, an aryl group, or a silyl group.

Abstract: Process for the recovery of transition metal from spent lithium ion batteries containing nickel, wherein said process comprises the steps of (a) heating a lithium containing transition metal oxide material to a temperature in the range of from 400 to 1200° C., (b) treating said heat-treated material with water, (c) treating the solid residue from step (b) with an acid selected from sulfuric acid, hydrochloric acid, nitric acid, methanesulfonic acid, oxalic acid and citric acid, (d) adjusting the pH value to 2.5 to 8, (e) removing compounds of Al, Cu, Fe, Zn or combinations of at least two of the foregoing from the solution or slurry obtained in step (d).

Abstract: A process including bringing a solid substrate in contact with a compound of general formula (I), (II), (III), or (IV) in the gaseous state where A is NR2 or OR with R being an alkyl group, an alkenyl group, an aryl group, or a silyl group, E is NR or O, n is 0, 1 or 2, m is 0, 1 or 2, and R′ is hydrogen, an alkyl group, an alkenyl group, an aryl group, or a silyl group.

Abstract: A process comprising: (a) distilling a melt comprising crude alkanesulfonic acid to completely or partly remove low boilers, wherein the low boilers are drawn off at the top of a distillation column or of a one-stage evaporation apparatus and a material stream comprising alkanesulfonic acid, high boilers and residual low boilers is withdrawn at the bottom of the distillation column or of the one-stage evaporation apparatus, (b) sending the stream comprising alkanesulfonic acid, high boilers and residual low boilers into a melt crystallization as the starting melt to obtain crystals formed from the alkanesulfonic acid, hydrates of the alkanesulfonic acid or a mixture of both suspended in mother liquor, (c) performing a solid-liquid separation to remove the crystals from the mother liquor, and (d) optionally washing the crystals to remove mother liquor adhering to the crystals.
