976-56-7 - Introduction

Open Data Unverified Data

Antioxidant 1222, chemically known as 2,2'-Methylenebis(4-methyl-6-tert-butylphenol), is a commonly used phenolic antioxidant. It is primarily employed in polymer materials (such as plastics, rubber, synthetic fibers, etc.) to prevent degradation and aging caused by oxidation during processing and use.

Key Features:

  1. Antioxidant Properties: Effectively scavenges free radicals, inhibiting oxidation reactions and extending the material's lifespan.
  2. Thermal Stability: Maintains excellent antioxidant performance even under high-temperature conditions.
  3. Compatibility: Exhibits good compatibility with various polymer materials, ensuring easy dispersion.
  4. Low Volatility: Minimizes evaporation during processing and use, providing long-lasting antioxidant effects.

Applications:

  • Plastics Industry: Used for oxidation resistance in polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and other plastics.
  • Rubber Industry: Prevents aging in natural and synthetic rubber.
  • Synthetic Fibers: Applied in polyester, nylon, and other fibers for oxidation protection.
  • Lubricants and Fuels: Added as an additive to prevent oxidation and deterioration of oils and fuels.

Precautions:

  • The appropriate dosage should be determined based on the specific material's processing conditions and application environment.
  • Store in a cool, dry, and well-ventilated area, avoiding high temperatures, moisture, and direct sunlight.

from

VIP web Author:

Who Yao Ruo

Abstract:

In this paper, 2, 6-di-tert-butylphenol is reacted with formaldehyde and dimethylamine to form N, n-dimethyl-3, 5-, di-tert-butyl-4-hydroxybenzylamine by Mannich reaction, the product is then reacted with a diethyl phosphonate to give the title compound. Its IR and ~ 1HNMR are consistent with the structure. The product is a hindered antioxidant, suitable for polyester fiber, polypropylene fiber and polyvinyl chloride fiber.
