2,6-Di-tert-butylphenol, identified by its CAS number 128-39-2, is a crucial organic compound that plays a significant role across various industrial sectors. Its unique chemical structure, featuring a phenol ring substituted with two tert-butyl groups at the ortho positions, imparts valuable properties, most notably its robust antioxidant capabilities.

Understanding the intrinsic properties, manufacturing processes, and diverse applications of 2,6-DTBP is essential for procurement managers, R&D scientists, and formulation chemists. As a dedicated manufacturer and supplier, we aim to provide clarity on this vital chemical.

Key Properties of 2,6-Di-tert-butylphenol

2,6-DTBP typically appears as a white to slightly yellowish solid. It boasts a melting point range of approximately 34-37 °C and a boiling point around 253 °C. Its low melting point means it can sometimes exist as a viscous liquid at slightly elevated room temperatures. Importantly, it is practically insoluble in water but soluble in many organic solvents such as benzene, ethanol, and hydrocarbons. This solubility profile dictates its suitability for different formulation types.

Industrial Production Methods

The industrial synthesis of 2,6-Di-tert-butylphenol primarily involves the Friedel-Crafts alkylation of phenol with isobutene. This reaction is typically catalyzed by acidic catalysts, often aluminum phenoxide, which promotes selective ortho-alkylation. The process requires careful control of reaction conditions, including temperature and the ratio of reactants, to maximize the yield of the desired 2,6-isomer and minimize the formation of unwanted byproducts like 2,4-di-tert-butylphenol. Procurement professionals looking to buy 2,6-DTBP often inquire about the production methods to ensure quality and consistency.

Diverse Applications

The primary function of 2,6-DTBP is as an antioxidant. Its ability to scavenge free radicals makes it invaluable for:

  • Polymer Stabilization: It is a key precursor for manufacturing advanced antioxidants that protect plastics like polypropylene and polyethylene from thermal and oxidative degradation during processing and use.
  • Fuel and Lubricant Additives: 2,6-DTBP directly prevents gum formation in aviation fuels and enhances the oxidative stability of engine oils, hydraulic fluids, and metal cutting fluids.
  • Chemical Synthesis: It serves as an intermediate in the production of other specialized chemicals, including certain pharmaceutical compounds and performance additives.
