Cyasorb 5411 - Preparation method

Open Data Verified Data

1. Diazotization reaction

Prepare a mixture of sulfuric acid and water, and add a certain amount of o-nitroaniline under stirring. Cool the system to 0~5 ℃, add 20% sodium nitrite solution dropwise, and maintain the temperature at 0~5 ℃ throughout the reaction process. After the reaction is completed, urea is added to decompose the remaining nitrite (detected using starch potassium iodide test paper). The product is orthonitrobenzene diazonium sulfate.

2. Coupling reaction

Add p-tert-octylphenol and ethanol to the reactor, stir to fully dissolve, and maintain at 0-5 ℃. Adjust the pH value to 7-9 using a 20% NaOH solution, and add the diazonium salt solution dropwise under this weakly alkaline condition until complete reaction occurs. Maintain a pH value of 7-9 during the reaction process. After the reaction, filter and wash to obtain 2-nitro-2 '- hydroxy-5' - teroctylazo benzene.

3. Glucose zinc powder reduction

Add an appropriate amount of ethanol and 20% NaOH solution to the coupling product, heat to 50-60 ℃, and add glucose solution dropwise. After the reaction is completed, cool to 40-50 ℃, adjust the pH value to 3 with 10% sulfuric acid, and filter to obtain solid nitrogen oxides. Add chlorobenzene, ethanol, and sulfuric acid to the nitrogen oxide, heat to 85-90 ℃, and add a certain amount of zinc powder in batches for reduction. After the reaction is completed, the final product is obtained through purification and refinement.

inorganic ultraviolet absorber light stabilizers used in history can be roughly divided into 4 categories, namely ultraviolet absorber, quenching agent, free radical spreading agent and light shielding agent. From the principle of action, it mainly works in three directions. One is to prevent ultraviolet rays from entering the product and resist the enemy outside the door. However, the shielding agent has no choice for light shielding. As a result, the product is opaque. The second is to capture free radicals caused by ultraviolet rays entering the polymer to prevent free radicals from further triggering other molecular breakage. In essence, it is to protect the overall integrity of the product at the cost of very few molecular bond breakage. Fading is easy to occur when using UV-sensitive pigments. Third, it absorbs the energy of ultraviolet rays and converts it into heat energy for emission, which is a good method. At present, the international concept of green consumption is increasingly strengthened, requiring products to have a long service life to protect limited resources. The toxicity of the product has attracted more attention. In this context, inorganic nano-ultraviolet absorbers came into being. Nanomaterials mean that the size of the material is at least one-dimensional between 1-100nm. At present, the powders used as ultraviolet absorbers are basically spherical particles. The particle size is equivalent to the ultraviolet wavelength, and the ultraviolet light wave undergoes strong reflection on the ion surface. This phenomenon is called the small size effect of nanomaterials. Under the effect of small size, nanomaterials can strongly shield ultraviolet rays, and the wavelength of visible light is much larger than the particle size. They will cause light diffraction through the particles, making nanomaterials have high permeability to visible light while shielding ultraviolet rays. Generally speaking, the outstanding advantages of inorganic ultraviolet absorber are: 1. High ultraviolet shielding efficiency and good visible light transmission filtration. 2. Excellent stability, long-term function, long-term maintenance of polymer products bright appearance, prolong the life of polymer products. 3. The products currently developed are basically non-toxic and have a wide range of applications. 4. As the biological, optical, electrical and magnetic properties of the particles have changed greatly after reaching the nanometer level, this will bring about the optimization of the mechanical properties of polymer materials, making it possible to produce functional materials. At present, high-strength plastics have been produced by using nanomaterials, and sterilization and self-cleaning functional coatings have been produced by using the high surface activity of nanomaterials.
Use Suitable for polystyrene, polymethyl methacrylate, polyester, rigid polyvinyl chloride, polycarbonate, ABS resin, etc.
