What is Solvent Violet 13?

Solvent Violet 13 is a chemical dye with a CAS registration number of 81-48-1 and is an anthraquinone compound. This dye appears as a purple-black powder, which is insoluble in water but well soluble in a variety of organic solvents, such as benzene, chlorobenzene, xylene and DMF. In concentrated sulfuric acid, Solvent Violet 13 appears dark green, but the color changes after dilution.

Its molecular formula is C21H15NO3 and its molecular weight is 329.35 g/mol. It has good fastness, temperature resistance and migration resistance. It has a bright color tone and blue light. It is an oil-soluble dye. Due to these properties, Solvent Violet 13 is mainly used in industry for pre-spun coloring of a variety of plastics, polyester fibers and textiles to provide long-lasting and bright color effects. In addition, it is used in the laboratory as a reagent for the photometric determination of boron.

In terms of storage, in order to maintain its properties unchanged, Solvent Violet 13 should be sealed and stored.

Solvent Violet 13 Uses

Chemical Analysis: Solvent Violet 13 can be used as a chemical reagent in the laboratory for specific analytical tests, such as the photometric determination of boron. Its specific absorption spectral properties make it an indispensable component in certain analytical methods.

Inks and printing: Due to its property of being insoluble in water but soluble in organic solvents, Solvent Violet 13 is suitable for the formulation of oil-based or solvent-based inks and is used in the printing industry to give printed matter a lasting and bright purple hue.

Plastic and resin coloring: In the plastics manufacturing industry, Solvent Violet 13 can be used as a colorant for plastics and resins, especially suitable for plastic products that require solvent resistance and high temperature resistance, such as toys, household items, and packaging materials.

Paints and Coatings: As a pigment component in solvent-based coatings, Solvent Violet 13 can provide long-lasting color effects and is suitable for coatings on metal surfaces, wood, leather, etc. that require chemical and abrasion resistance.

Fiber and Textile Dyeing: Although its oil-soluble characteristics prevent it from being used directly for water-based textile dyeing, Solvent Violet 13 can play a role in specific fiber treatments or dyeing of oil-based fibers, especially in non-traditional textile dyeing processes. middle.

Scientific research and teaching: In chemical education and scientific research, Solvent Violet 13 can be used as a teaching demonstration material or an example dye in scientific research experiments to help students and researchers understand the properties of dyes and their behavior in different media.

Solvent Violet 13 Advantages

Good solubility: The biggest feature of Solvent Violet 13 is its good solubility in organic solvents while being insoluble in water. This property makes it ideal for use in non-aqueous systems such as inks, paints, plastics and special-purpose coatings where high solvent resistance and color stability are required.

Vivid Color: Provides an intense, long-lasting purple hue, which is especially important in industries that require vivid color expression, such as printing inks, plastic product dyeing and specialty marking materials.

Good thermal stability and light resistance: Solvent Violet 13 can still maintain good color stability under high-temperature processing and long-term light conditions, which is very important for products used outdoors, such as outdoor billboard coatings, plastic building materials, etc. performance.

Chemical stability: As an organic dye, Solvent Violet 13 is relatively stable in a specific chemical environment and does not easily react with other chemicals, which ensures its applicability in complex formulations and long-term storage stability.

Specificity for specific applications: In certain specialized areas, such as as a reagent for the photometric determination of boron, Solvent Violet 13 exhibits specific chemical reactivity and selectivity, which is a significant advantage in analytical chemistry.

Economical: Compared with some high-end or special-purpose dyes, Solvent Violet 13 may be cost-effective, especially in industrial production that requires the use of large quantities of dyes, and its cost-effectiveness may be higher.
