C.I. Solvent Violet 13 - Uses and synthesis methods

overview

solvent purple 13 is purple-black powder, insoluble in water, soluble in benzene, chlorobenzene, xylene, DMF and other organic solvents, dark green in concentrated sulfuric acid, diluted to produce olive to red blue precipitate.

application

solvent violet 13 can be used for coloring various resin plastics, such as polyacrylic resin, ABS resin, polystyrene, plexiglass, polyester resin, polycarbonate, etc., to obtain red and blue; It has excellent heat resistance, sun resistance and migration resistance, good tinting power, high transparency and wide application range.

use

1, used as a enzyme reagent for the determination of boron. Mainly used for raw pulp coloring of polyester fibers, and can also be used to prepare masterbatch for polyester

2. photometric determination of boron.

3. Used for ordinary dyeing and rapid dyeing of polyester and its blended fabrics

production method

Using 1, 4-dihydroxyanthraquinone and p-toluidine as raw materials, 1, 4-dihydroxyanthraquinone is first reduced to its leuco, then condensed with p-toluidine, and oxidized to obtain the product. The finished product is filtered and dried.
