Definitions
- the invention relates to a process for the formation of organic pigments.
- Organic pigments often accumulate in the synthesis in coarsely crystalline form with very heterogeneous particle size distribution.
- the crude pigments are therefore usually subjected to a formation.
- a grinding of the crude pigment and subsequent recrystallization of the millbase in an organic solvent is known, or the grinding is carried out as a wet grinding in aqueous suspension in high-speed stirred ball mills.
- the methods described achieve particle size reduction and thus an improvement in the coloristic properties of the pigments, sometimes with a high expenditure of time, it is difficult to control the particle size of the pigments obtained, and the pigments are frequently used in a number of applications. For example, as a colorant for metallic paint for the automotive industry, insufficient because too broad particle size distribution on.
- WO 02/00643 discloses a process for the formation of quinophthalone crude pigments, in which the crude pigment obtained in the synthesis is subjected to milling in the absence of grinding aids, and the resulting millbase is subsequently removed in the presence of a quinophthalone derivative in an organic solvent or a mixture of organic solvent and crystallize water.
- derivatives are sulfonic acid derivatives of quinophthalone pigments.
- WO 2004/048482 discloses a process for the formation of organic pigments, in which the pigment is dissolved in concentrated sulfuric acid and the sulfuric acid solution is mixed with water in the presence of a condensation product of naphthalenesulfonic acid and formaldehyde as crystallization modifier.
- the crystallization modifier is added before mixing the sulfuric acid pigment solution or it is generated in this by reacting 1- and 2-naphthalenesulfonic acid with formaldehyde in situ.
- a disadvantage of this in-situ synthesis is that condensation products with broad and poorly defined molecular weight distribution result.
- the object of the invention is to provide an advantageous and easy to carry out process for the formation of organic pigments, which gives pigments with very good coloristic properties.
- the object is achieved by a method for forming (finishing) an organic pigment, in which the pigment is dissolved or dispersed in a mineral acid and from the solution or dispersion of the pigment by mixing with an aqueous diluent in the absence of a sulfonate-containing condensation product of an arylsulfonic acid and an aliphatic aldehyde, characterized in that the crystallized organic pigment is allowed to mature in aqueous presence in the presence of a surfactant or in the presence of an additive which increases the solubility of the pigment.
- the crystallization step by mixing the sulfuric acid pigment solution with the aqueous diluent is expressly carried out in the absence of a crystallization inhibitor condensation product of an arylsulfonic acid and an aliphatic aldehyde.
- the polymeric crystallization inhibitors are usually condensation products of one or more naphthalenesulfonic acids, such as 1-naphthalenesulfonic acid, 2-naphthalenesulfonic acid or mixtures thereof, and one or more different aliphatic aldehydes, usually formaldehyde. Condensation products of one or more different hydroxyarylsulfonic acids and an aliphatic aldehyde and optionally urea and optionally alkali metal sulfite are also used as such crystallization inhibitors.
- the organic pigment is dissolved or dispersed in a mineral acid and allowed to crystallize from the solution or dispersion by dilution with an aqueous diluent in the absence of a polymeric crystallization inhibitor.
- Preferred mineral acid is sulfuric acid.
- the pigment is dissolved in concentrated sulfuric acid.
- the additive or surfactant which increases the solubility of the pigment is already present in the aqueous diluent when the mineral acid pigment solution is mixed with the aqueous diluent, or it is subsequently added. It may also be present in the mineral acid pigment solution or in the dilute and the pigment solution. It can also be added to the previously isolated as a solid and then redispersed pigment.
- the mixing is carried out by combining the mineral acid pigment solution and the aqueous diluent by means of a mixing nozzle.
- Aqueous diluent is generally water.
- the crystallization can also be effected by pouring the mineral acid pigment solution into the aqueous diluent, preferably ice-water.
- the concentration of the pigment in the mineral acid pigment solution is 1 to 30% by weight.
- the volume of the admixed aqueous diluent is generally 1 to 12 times the volume of the mineral acid pigment solution.
