2,5-Di-tert-butylhydroquinone is a substance added in small quantities to hydrocarbons which are susceptible to oxidation, such as rubbers, plastics, foods, and oils to inhibit or slow oxidative processes, while being itself oxidized. Antioxidants work in two different ways. Appearance:Off-white crystals. Antioxidants work in two different ways. In primary antioxidants (also called free-radical scavengers), antioxidative activity is implemented by the donation of an electron or hydrogen atom to a radical derivative. As a non-poisoning, odorless and colorless antioxidant, DTBHQ is highly safe with no pollution to the products and environment. Sometimes, chelating agents are added to scavenge metal impurities which can initiate decomposition.
Purity (HPLC):99% min. DTBHQ has been proved to be a non-poisoning material through toxicity tests, for the white mices LD 5010/kg, being outstanding security (It is generally stipulated that the materials are non-poisoning when LD50=2.0/kg).
CAS number: 88-58-4; Linear, 4-(OH) 2 Molecular weight: 222.32; Beilstein Registry Number: 2049542; Enzymology committee Numbers: 201-841-8 MDL number: MFCD00008825 PubChem Substance ID: 24847124. Butylated hydroxytoluene (BHT) is a common example of hindered phenolic antioxidant.
2,5-Di-tert-butylhydroquinone is Used as antioxidant in rubber processing.
Packaging: 25k g fiber drum. Principal component content≥99﹪,Relative density:1.10, melting point: 214～219, Soluble in Acetone, ethanol, ethyl acetate and carbon disulfide,slight soluble in Benzene,insoluble in oil. it is Non-toxic、Colorless, non-polluting, dispersible.
Synergistic effect is expected when primary antioxidants are used together with secondary antioxidants as primary antioxidants are not very effective against the degradation by UV oxidation.
