Copper salts pigment

The list ends here other heterocycles have failed to gain significance as coupling components for diazonium salts. The only exception is 2,4-hydroxyquinoline, which is used as a starting material for a copper complex pigment (Sec. 2.10.1.1). 

Modern methods of manufacturing this probably oldest representative among synthetic organic pigments involve dissolving aniline in strong sulfuric acid. Oxidation is achieved with sodium dichromate in the presence of a copper salt or one of the above-mentioned oxidation catalysts. Oxidation with sodium chlorate initially affords an indamine polymer (pernigraniline) ... 

Basic copper carbonate is used as a pigment in paint and varnish as a fungicide for seed treatment as an insecticide in pyrotechnics and in the manufacture of other copper salts. The compound is also added in small quantities to animal and poultry feed to supply nutritional copper requirements. 

Copper(lI) hydroxide is used as a mordant in pigments for staining paper as an additive to cattle feed as a catalyst as a fungicide and in the preparation of several copper salts.

Use Pigments, pyrotechnics, insecticides, copper salts, coloring brass black, astringent in pomade preparations, antidote for phosphorus poisoning, smut preventive, fungicide for seed treatment, feed additive (in small amounts). 

Use Copper salts, mordant, cuprammonium rayon, pigment, staining paper, feed additive, pesticide and fungicide, catalyst. 

Use Agriculture (soil additive, pesticides, Bordeaux mixture), feed additive, germicides, textile mordant, leather industry, pigments, electric batteries, electroplated coatings, copper salts, reagent in analytical chemistry, medicine, wood preservative, preserva-... 

Self polishing co-polymers are tributyltin and methyl methacrylate co-polymers into which copper salts and other biocides, together with appropriate pigments are incorporated. In contact with sea water hydrolysis occur, releasing tributyltin and producing a smoother surface in contact with the water. The rate of hydrolysis depends on the temperature and pH and the pigments incorporated in the resin. 

Para brown n. Bright brown pigment of good staining power, made by treating para red with copper salts. 

Synonims quaternary ammonimn compounds, bis(hydrogenated tallow alkyl)dimethyl, salts with bentonite, bentonite, montmorillonite copper phthalocyanine Pigment Blue 15 tungsten disulfide zinc oxide -i- 1,3,5-benzene tricaboxylic-(N-4-ll uorophenyl)triamine... 

Chlorinated rubber, e.g. Duroprene (ICI Figure A3.7), is a saturated polymer. Although more stable than rubber, it is sensitive to light and ultraviolet, probably in a similar fashion to PVC, resulting in oxidation and discoloration. Chlorinated rubber can react with various pigments such as zinc oxide, copper salts, Prussian blue (ferric ferrocyanide) and ultramarine to form cross-Unks.
