| | 亜りん酸トリス(2,4-ジ-tert-ブチルフェニル) Usage And Synthesis |
| 外観 | 白色の結晶性粉末 | | 溶解性 | トルエン及びヘキサンに溶けやすく、アセトンにやや溶けにくく、水及びメタノールにほとんど溶けない。 | | 用途 | 汎用の固体ホスファイト。ホスファイト系酸化防止剤の中でも特に耐加水分解性に優れる。
| | 用途 | 酸化防止剤定量用標準品。 | | 説明 | ANTIOXIDANT 168 is a secondary antioxidant with excellent resistance to extraction by water, low volatility and high heat stability. It can effectively decompose hydroperoxides produced during the processing of polymeric materials. ANTIOXIDANT 168 usually not used alone, is compounded with hindered phenolic primary antioxidants such as 1010 to improve thermostability of polymer during the processing. There are over ten kinds of blends of 168 with phenolic antioxidants, widely use in the polymer materials such as PE, PP, PA, PC, ABS and so on. | | 使用 | This product is an excellent Antioxidant wnameely applied to polyethylene, polypropylene, polyoxymethylene, ABS resin, PS resin, PVC, engineering plastics, binding agent, rubber, petroleum etc. for product polymerization. | | 使用 | Tris(2,4-tert-butylphenyl) Phosphite is an intermediate in the synthesis of Tris(2,4-di-tert-butylphenyl)phosphate (T884500), a processing stabilizer for polymers. | | 主な応用 | Antioxidant 168 is a kind of phosphite ester antioxidant as processing stabilizer, used for polypropylene, polyethylene, and adhesives. The amount to be used may be 0.1%~1.0% depending on the substrate, processing conditions, and requirements of the end application. Blends with hindered phenols are particularly effective.In addition, they use combination with light stabilizers when need. | | 定義 | ChEBI: Phenol, 2,4-bis(1,1-dimethylethyl)-, phosphite (3:1) is an alkylbenzene. | | 一般的な説明 | Tris(2,4-di-tert-butylphenyl) phosphite is a triaryl based phosphite that can be used in catalysis and metallation. Its characteristic to undergo metallation reaction and provide a cost effective synthetic processes allows it to be useful in biaryl coupling reactions. | | 燃焼性と爆発性 | Not classified | | 安全性 | Antioxidant 168 is approved for indirect food contact applications. | | Properties and Applications |
