The present invention relates to an improved process for the production of alkanesulfonic acids.

Process for manufacturing alkanesulfonic acids

The present invention relates to a process for the recovery of transition metals from battery materials comprising (0.1) providing a battery material which comprises oxidic nickel and/or cobalt compounds, (1.1) heating the battery material above 350° C. to yield a reduced material which contains nickel and/or cobalt in elemental form, (2.1) carbonylating the reduced material with carbon monoxide optionally in the presence of a reactive gas to yield a solid carbonylation residue and a volatile carbonyl which comprises nickel and/or cobalt carbonyl containing compounds, and (3.1) separating the volatile carbonyl from the solid carbonylation residue by evaporation.

Battery recycling by reduction and carbonylation

The present invention relates to a process for manufacturing of anhydrous methanesulfonic acid (MSA) and to methanesulfonic acid manufactured by said process and its uses.

Process for the production of anhydrous methanesulfonic acid from methane and SO3

The invention relates to a process for preparing silica-coated particles of an inorganic expanding agent, the silica-coated particles and their use. The silica-coated particles show a delayed release of the expanding agent particularly in alkaline medium and at elevated temperatures. They are therefore useful in the oil and construction industry.

Silica-coated expanding agents and their use in cementitious systems

A polymer mixture in solid or aqueous form includes a content of from 5 to 95% by weight of a first polymer and a content of from 5 to 95% by weight of a second polymer. The first polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 20 000 g/mol. The second polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 50 000 g/mol. The polymer mixture can inhibit precipitation and sedimentation of calcium salts and magnesium salts in water-bearing systems.

Process for producing composite materials by reactive spray-drying, where a liquid phase A, which comprises inorganic cations, and a liquid phase B, which comprises anions which, with the inorganic cations, form a salt that is insoluble in the mixture of the liquid phases are sprayed together using at least one multi-substance nozzle, and where at least one hydrophobic active ingredient is present in dissolved form in at least one liquid spraying phase, and where the salt formed from the cations of phase A and the anions of phase B has a solubility of less than 0.02 mol/l in the neutral aqueous medium.
