Abstract: The present invention is in the field of processes for the generation of thin inorganic films on substrates, in particular atomic layer deposition processes. It relates to a process for preparing metal films comprising (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 reducing agent in the gaseous state, wherein the reducing agent is or at least partially forms at the surface of the solid substrate a carbene, a silylene or a phosphor radical.

Abstract: The invention relates to a process for reprocessing alkane sulfonic acid, which is used in a chemical process as an agent, catalyst, or solvent, which comprises the following steps: (a) separating a stream containing alkane sulfonic acid from a reaction mixture which accumulates in the chemical process, (b) feeding the stream containing alkane sulfonic acid as output melt to melt crystallisation, wherein crystals of the alkane sulfonic acid, of hydrates of the alkane sulfonic acid or a mixture of the two are formed, suspended in mother liquor, (c), carrying out a solid-liquid separation in order to separate crystals out of the mother liquor, (d) if necessary, washing the crystals in order to remove mother liquor adhering to the crystals, (e) feeding back the crystals separated from the mother liquor and possibly washed into the chemical process.
