Uses and synthesis of tert-Butylhydroquinone powder

tert-Butylhydroquinone powder (also known as tert-butylhydroquinone, abbreviated as TBHQ) is a phenol, consisting of hydroquinone with a tert-butyl group added.

tert-Butylhydroquinone CAS 1948-33-0 is white or slightly reddish brown crystalline powder, has a very light special fragrance, almost insoluble in water (about 5 ‰), tert-Butylhydroquinone Raw Materials soluble in ethanol, ethyl acetate, ether and other organic solvents.

Applications / Functions of tert-Butylhydroquinone powder

1. Antioxidant. tert-Butylhydroquinone powder is suitable for crude oils and highly unsaturated fats and oils, such as sunflower oil. For cooking oils and bakery products, it is suitable to be used in combination with BHA, but it is suitable for cooking and frying products.
2. Food oil additive testing.
3. tert-Butylhydroquinone CAS 1948-33-0 It has the effect of preventing oxidation on most oils and fats, plastics, rubber, etc. It does not change colour when it meets iron or copper. It does not change colour when it meets iron or copper, but it can turn pink when there is alkali. Excellent antioxidant property.

Physicochemical Property of tert-Butylhydroquinone powder

White to light grey crystal or crystalline powder. There is a very slight special smell. tert-Butylhydroquinone Raw Materials Soluble in ethanol, acetic acid, ethyl ester, isopropyl alcohol, ether, and vegetable oil, lard and so on, a few insoluble in water (25 ℃, <1%; 95 ℃, 5%). Boiling point 300℃, melting point 126.5～128.5℃.

tert-Butylhydroquinone powder has the effect of preventing crotch failure on most oils and fats, especially vegetable oils. It does not change colour when it meets iron or copper, but it can turn into pink colour if there is alkali.

Production methodprocess of tert-Butylhydroquinone powder

• Phosphoric acid catalytic method in the toluene, hydroquinone and 60% of the mixture of phosphoric acid add isobutene or tert-butyl alcohol, the reaction at 105 ℃ to produce tert-Butylhydroquinone CAS 1948-33-0 , the yield is 89%.
• 
• Sulphuric acid catalysed reaction of hydroquinone with tert-butanol in the presence of concentrated sulphuric acid or sulphonic acid at 90 °C to form 41.0% (mo1) of tert-Butylhydroquinone powder and 5.1% (mo1) of 2,5-di-tert-butylhydroquinone.
