Solvent Violet 13 Applications

As a part of organic pigments, solvent dyes have the residential or commercial properties of natural pigments and have their very own features. When coloring with the exact same color, solvent dyes have the feature of color enhancement, and their stamina is a lot higher than that of organic dyes. They can be utilized for transparent or opaque tinting. They can be used as polymer products Colorants are called for to have excellent weather condition resistance; adapt to greater processing temperature; do not bleed or move on the refined parts. These conditions are far better than other dyes, however the rate is a little higher. Among them, solvent violet 13 will have a great development prospect as a popular dye.

There are lots of structural kinds of solvent dyes, and also the common ones are coumarin type, phthaleinone, etc as well as their derivatives. The framework of solvent violet 13 comes from anthraquinones. This sort of dye has exceptional application efficiency, bright shade, as well as the light shade has fluorescent I’I, and the strength is really high. It is additionally widely utilized, especially for the coloring of decors. Solvent violet 13 dyes with yellow as well as red as the primary chromatograms are mostly 1-alkylamino or 1,5- as well as 1,8-dialkylamino replacements of onion, while 1,4-dialkylamino The substituents are mainly blue as well as environment-friendly, and also the 2-alkyl or 2-arylamino substituents of onion can additionally be by-products of solvent violet 13. Solvent violet 13 has a reasonably high melting point, generally in between 250 ° C as well as 300 ° C, as well as its superb thermal security determines its application performance. It is commonly made use of in the coloring of polyester, plastic as well as other polymer substances. Solvent Violet 13 has a temperature resistance of as much as 350 ° C and also can be used on a lot of plastics. Solvent violet 13 is not just utilized for plastic coloring, but likewise can be utilized for tinting liquid crystal display products because of its dichroism. Due to the outstanding light fastness of solvent violet 13, in order to broaden a wider series of applications, organic bases are often introduced to neutralize the excess acid to make the compound electrically neutral, to make sure that the color is soluble in non-polar in neutral solvents. Additional usage fundamental dyes as standard teams to counteract acidic metal complex dyes llz, and a new dye will certainly be obtained, which is different from the original dye in terms of hue as well as application efficiency. It can be utilized for the coloring of inkjet ink as well as metal aluminum foil. Because of the greatly improved solubility of solvent violet 13 in non-polar solvents, it can end up being a liquid solvent dye. As an example, tartrazine (acid dye) can be reacted with organic base to create a brand-new fluid solvent color. Residential comparable varieties such as: solvent yellow 21, solvent orange 62, solvent red 8, solvent red 100, solvent red 122, solvent blue 24, solvent blue 38, solvent black 27, solvent black 34, solvent black 35, and so on.

Preparation of Solvent Violet 13

Making use of 1,4-dihydroxyanthraquinone and also p-nitrotoluene as starting materials, methanol as solvent, iron powder as reduction catalyst, hydrogen as reducing representative, boric acid as condensation stimulant, reduction as well as condensation reactions happen, and air oxidation is obtained Solvent Violet 13. The new path of this one-pot synthesis of solvent violet 13 places all the raw materials right into the container together, which saves the post-treatment process in the intermediate actions and saves a lot of manpower and also product sources. details as follows:

First put methanol, 1,4-dihydroxyanthraquinone, p-nitrotoluene, iron powder, and boric acid right into a pressure vessel in sequence, secure the vessel and also replace it with nitrogen, after that stir as well as raise the temperature to 50-60 ° C, and after that inject hydrogen for hydrogenation Reduction, when the reaction system quits absorbing hydrogen, control the heat preservation response at 60-70 ° C for greater than 2 hrs, warm up after the reaction, and also execute condensation reaction at 90-100 ° C for more than 5 hrs, and release after the response pressure, lower the temperature, pass air to perform the oxidation reaction, and also finally add hydrochloric acid for beating, the beating temperature is 60-70 ° C, filter, clean, as well as dry to obtain Solvent Violet 13.

Wherein, the mass proportion of 1,4-dihydroxyanthraquinone to methanol is 1:(1.1 ~ 3.0); the mass proportion of 1,4-dihydroxyanthraquinone to p-nitrotoluene is 1:(0.5 ~ 0.7); 1, the mass proportion of 4-dihydroxyanthraquinone to iron powder is 1: (0.04 ~ 0.12), the mass proportion of 1,4-dihydroxyanthraquinone to boric acid is 1: (0.1 ~ 0.3); The mass ratio of hydroxyanthraquinone to hydrochloric acid is 1: (0.2-0.8).
