2,4-Di-tert-butyl-phenol, CAS 96-76-4, is an organic chemical compound with structural formula 2,4-((CH3)3C)2C6H3OH. Popularly known as 2,4-DTBP, this product is a high volume intermediate known to possess antioxidant, anti-inflammatory properties. 2,4-dTBP shows remarkable cytotoxicity insecticidal, nematicidal, antiviral, antifungal, phytotoxicity and antibacterial activities. The molecule has 2 tertiary butyl groups attached to the phenol molecule at ortho and para position.


Production of 2 4 di tert butyl-phenol

  • 2,4-DTBP or 2 4 di tert butyl-phenol can be produced by the alkylation of phenol and tert-butyl alcohol with mesoporous molecular sieves containing tungstophosphoric acid (TPA-SBA-15) as the catalysts that can directly be synthesized by the sol-gel technique. The parameters of the reaction like temperature, space velocity in the reactor, and the composition of the catalysts are based on the feedstock purity and ratios. The feedstock ratio, the composition of catalysts, the temperature of the reactors are all optimized to yield a maximum quantity of 2,4-DTBP. At Vinati Organics Limited, this colourless chemical compound is prepared via the Friedel-Crafts alkylation of phenols with high purity isobutylene using an acid-based catalyst.


Uses and Applications

2,4-Dtbp and its derivatives are used commercially as UV stabilizers as well as antioxidants for hydrocarbon-based products varying from petrochemicals to plastics. It is a colourless solid alkylated phenol that is used to prevent gumming in aviation fuels. 2,4-Di-tert-butyl-phenol is also used in the synthesis of CGP-7930, probucol, and nicanartine.

The dominant use of 2,4 di-tert-butyl-phenol is as an intermediate to manufacture an antioxidant named Antioxidant 168. This antioxidant is one of the most widely used secondary antioxidants in all polyolefins/plastics. 2,4-DTBP is also used as an intermediate to make a light-protection agent for the stabilization of polymers. The product can also be used to manufacture some complex pharmaceutical APIs. 2,4-Dtbp is used to study its alkylation reaction with cinnamyl alcohol in the presence of substituted disordered hexagonal molecular silica catalysts.
