A method of finishing an organic pigment by dry-comminuting said pigment in the presence of a sulfonato-functional condensation product of an arylsulfonic acid and at least one aliphatic aldehyde having 1 to 6 C atoms as crystallization modifier, dispersing the resulting mixture of pigment and crystallization modifier in mineral acid, and swelling the pigment in the presence of the crystallization modifier in mineral acid.

Method of finishing organic pigments

The invention relates to processes for producing nanoparticles, especially pigment particles, comprising the following steps: i) bringing a base substance () into the gas phase, ii) generating particles by cooling or reacting the gaseous base substance (), and iii) applying electrical charge to the particles during particle generation in step ii) in a nanoparticle generation apparatus. The invention further relates to apparatus for producing nanoparticles, having a feed line () for transporting the gas stream () into the apparatus, a particle generation and charging area for substantially simultaneous generation and charging of nanoparticles, and a takeoff line () for transporting the charged nanoparticles from the particle generation and charging area.

Method and device for producing nanoparticles

A method for reducing the particle size of amino acid crystals using ultrasound is discussed.

Crystallization of amino acids using ultrasonic agitation

The present invention relates to a process for crystallizing small particles with a narrow particle size distribution. The crystals of the invention are obtained by introducing ultrasound into a solution or suspension of the substance to be crystallized while simultaneously adjusting a particular specific stirring power.
