1,3,5-Trimethyl-2,4,6-tris(3,5-di-tert-butyl-4-hydroxybenzyl)benzene Use and Manufacturing
(1) After adding catalyst B to mesitylene, stirring uniformly to obtain a mixture a;(2) adding compound (I) to a dichloromethane solvent, stirring to obtain a mixture b;(3) The mixture b is added dropwise to the mixture a while stirring, reacted at 10 ° C for 2 h, cooled to room temperature to obtain a mixture c;(4) After the mixture c obtained in the step (3) is filtered, the catalyst B is recovered to obtain a filtrate d;(5) The filtrate d obtained in the step (4) is concentrated to dryness to obtain a crude product, and the crude product is recrystallized from n-heptane. The recrystallization is carried out by adding n-heptane to the crude product, heating to 85 ° C for 2 h, and then cooling. Crystals are obtained at room temperature, and the crystals are passed.The above compound (II) is obtained by filtration and dried under vacuum.1) In a 500 ml four-necked flask equipped with a motorized stirrer, thermometer and condenser, 30 g of 2, 6-di-tert-butyl-4-methoxymethylphenol and 65 ml of dichloromethane were added.Control the temperature at 0-10 ° C, add 4g of mesitylene, mix well, continue to cool down to 0-5 ° C, Gradually add 30 g of sulfuric acid and incubate at 0-5 ° C for 3-4 h to obtain a reaction product.2) 1 g of Na2CO3 was added to the reaction product, and the reaction was neutralized at room temperature for 1 hour. The material after the neutralization reaction was poured into a water separator, 20 ml of water was added, and the mixture was washed with water for 0.5 hour under heating and refluxing, and the mixture was cooled and allowed to stand, and the aqueous phase was repeatedly washed with water to pH 7. The organic phase was evaporated to dryness at 90 ° C, and dichloromethane was used. 100 mL of n-heptane was added to the residue, and the mixture was heated to reflux. After the material was sufficiently dissolved in n-heptane, 40percent-50percent of n-heptane was evaporated under reduced pressure, then cooled to below 8 ° C, crystallized and filtered. The product was washed with a small amount of cold n-heptane and dried to give a white crystalline material, that is, an antioxidant 330, with a yield of 90percent.Mesitylene (12 g, 0.1 mol) and 2, 6-di-tert-butyl-4-methoxymethylphenol (80 g of 98percent, 0.31 mol) were added to a reactor containing acetic acid (280 g) and the mixture was stirred at room temperature under nitrogen. Sulfuric acid (0.5 g of 98percent) was added and the reaction mixture was heated at 60
This product is a high molecular weight multi-component hindered phenolic antioxidant with good heat resistance, no pollution, no coloring, low volatility, etc. It is an excellent antioxidant for high-density polyethylene, polypropylene and rubber. It is also used in The amount of plastic products such as polyvinyl chloride, polyamide, ABS resin and polyester is generally 0.1 to 0.5 parts.
