| overview | 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer, alias antioxidant RD in Chinese, with CAS number 26780-96-1, is an industrial catalyst plastic rubber additive. 2,2,4-trimethyl -1,2-dihydroquinoline polymer chemical formula C36H45N3, molecular weight 519.76300, melting point 2-94°C, density 1.08, boiling point> 315°C, flash point 118.6°C, refractive index 1.548, vapor pressure 0.000262mmHg at 25°C. Synthetic rubber suitable for NR and CR, such as IR,BR and SBR, has excellent thermal and oxygen aging resistance, but cannot prevent bending and cracking of the rubber. |
| application | 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer is an industrial catalyst or plastic rubber additive. 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer is an industrial catalyst or plastic rubber additive. Examples of its application are as follows: Prepare a material with sound insulation function. The sound insulation material includes 100 parts of nitrile rubber, zinc oxide, stearic acid, magnesium oxide, 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer, graphite powder, carboxyl silicone oil, accelerator, vulcanizing agent, wherein the material includes components in parts by weight: 100 parts of nitrile rubber, 4-7 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 8-12 parts of magnesium oxide, 2,2, 4-trimethyl-1, 1.5-3.5 parts of 2-dihydroquinoline polymer, 7-12 parts of graphite powder, 3-6 parts of carboxyl silicone oil, 0.5-1.5 parts of accelerator and 2-6 parts of vulcanizing agent. The unit volume of the material is lighter than other sound insulation materials, which can reduce the weight in use, reduce the overall quality of the applied components, have good sound insulation and attraction performance, and have long-term stable and reliable sound insulation attraction performance. |
| preparation | aniline and benzenesulfonic acid are put into a kettle reactor equipped with a condenser device in 8.9 parts by mass and 0.52 parts by mass respectively, heated and melted under stirring and raised to 155 ℃, acetone is added dropwise, and the temperature is kept at 155~165 ℃. after 13 parts by mass of acetone are added, the condensation reaction was carried out under the reflux of acetone at a temperature of 155~165 ℃ until the end point. The product is sent to a distillation tower, the water is distilled and acetone is recovered, then the reduced pressure distillation is carried out, and the fraction with boiling range of 130~140 ℃(2kPa) is collected to obtain monomer 2,2, 4-trimethyl-1, 2-dihydroquinoline. In the enamel reaction kettle, 8 parts of 30% hydrochloric acid are first added, water is added under stirring, diluted to about 17%, heated to 80 ℃, monomer is slowly added dropwise, and polymerization is carried out at a temperature of 95~98 ℃. After dropping the monomer, the reaction continued for 4 hours. 15% NaOH solution was added for neutralization to make the reaction material neutral. Then it is cooled, crystallized, filtered, washed and dried to obtain the finished product of 2,2, 4-trimethyl-1, 2-dihydroquinoline polymer. |
| use | mainly used as rubber antioxidant, suitable for natural rubber and synthetic rubber such as nitrile, styrene butadiene, ethylene propylene and chloroprene |
