The present invention relates to a process for preparing high-purity lithium fluoride proceeding from lithium carbonate, and to lithium fluoride having a preferred morphology.

Production of high-purity lithium fluoride

The present invention relates to a process for preparing chromium(III) oxide by reaction of alkali metal chromate with gaseous ammonia, subsequent hydrolysis, isolation of the hydrolysis product and calcination.

Process for preparing chromium(III) oxide

Process for preparing chromium(III) oxide, which comprises the steps:

A process for preparing benzomorpholine derivatives is described, in which an o-nitrophenoxy carbonyl compound is hydrogenated in the presence of extraneous metal-doped sponge metal catalysts based on nickel or cobalt with ring formation.

Process for preparing benzomorpholine derivatives by hydrogenating o-nitrophenoxy carbonyl compounds

A process for preparing acyl amide compounds is described, in which a recrystallized o-nitrophenoxy carbonyl compound is hydrogenated with hydrogen gas in the presence of a nickel sponge metal catalyst with ring closure to form a benzoxazine, which is then reacted with an acyl halide to give the corresponding acyl amide compound.

Process for preparing acyl amide compounds

Process for preparing A silver-containing, disperse, water-containing formulation useful for producing electrically conductive and/or optically reflective coatings, which comprises (i) reacting a silver salt solution with a solution containing hydroxide ions, wherein at least one of said solutions comprises a polymeric dispersant, to produce an AgO sol, (ii) reacting the AgO sol obtained from step i) with a reduction agent, and (iii) purifying the solution obtained from step ii).

Process for preparing silver-containing aqueous formulation useful for electrically conductive or reflective coatings

A silver-containing, disperse, water-containing formulation and its use to produce electrically conductive and/or optically reflective coatings is described. The formulation contains at least

Silver-containing aqueous formulation and its use to produce electrically conductive or reflective coatings

A method is described of treating aluminium-metal alloys with organic or inorganic bases by exposing them to an aqueous solution of the base, removing the aqueous base and washing the treated alloy material, the leaching process being monitored, during the time of exposure to the base, on the basis of the potential which is established at a measuring electrode as a result of the treated aluminium-metal alloy and the hydrogen which may be formed during the reaction.
