PRODUCTION OF BUTYLATED HYDROXYTOLUENE (BHT):
Industrial production;
The chemical synthesis of Butylated Hydroxytoluene (BHT) in industry has involved the reaction of p-cresol (4-methylphenol) with isobutylene (2-methylpropene), catalyzed by sulfuric acid:

CH3(C6H4)OH + 2 CH2=C(CH3)2 → ((CH3)3C)2CH3C6H2OH
Alternatively, Butylated Hydroxytoluene (BHT) has been prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation followed by hydrogenolysis.

REACTIONS OF BUTYLATED HYDROXYTOLUENE (BHT):
The species behaves as a synthetic analog of vitamin E, primarily acting as a terminating agent that suppresses autoxidation, a process whereby unsaturated (usually) organic compounds are attacked by atmospheric oxygen.
Butylated Hydroxytoluene (BHT) stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides.
Butylated Hydroxytoluene (BHT) effects this function by donating a hydrogen atom:

RO2• + ArOH → ROOH + ArO•
RO2• + ArO• → nonradical products

where R is alkyl or aryl, and where ArOH is Butylated Hydroxytoluene (BHT) or related phenolic antioxidants.
Each Butylated Hydroxytoluene (BHT) consumes two peroxy radicals.

The electron-donating alkyl groups on the ortho and para positions of Butylated Hydroxytoluene (BHT) increase the electron density of the phenolic hydroxyl moiety through the inductive effect and the hyperconjugation effect, reduce the bond dissociation energy of the phenolic hydroxyl group, and enhance its reactivity to lipid free radicals.

Meanwhile, the phenoxy radical generated by Butylated Hydroxytoluene (BHT) is stabilized due to the delocalization of unpaired electrons around the aromatic ring and the steric hindrance effect of ortho tert-butyl groups.
Isobutene is one of the possible degradation products formed by Butylated Hydroxytoluene (BHT) oxidation with computational studies suggesting that there are two possible mechanisms that can lead to isobutene formation, with the OH addition pathways at the C2 site of Butylated Hydroxytoluene (BHT) more likely to result in isobutene formation than pathways of H abstracts from the t-butyl group.

INDUSTRIES of BUTYLATED HYDROXYTOLUENE (BHT):
*Food & Beverage
*Personal Care & Cosmetics
*Pharmaceutical & Nutraceutical
*Agriculture

SOURCES of BUTYLATED HYDROXYTOLUENE (BHT):
Instead of being added directly to the food itself, Butylated Hydroxytoluene (BHT) is usually added to the packaging material from where it can vaporize into the food during storage.
Since Butylated Hydroxytoluene (BHT) may be classified as an incidental food additive when used in this manner, it does not legally need to be listed with other ingredients on the food label.
Processed foods most likely to feature Butylated Hydroxytoluene (BHT) include chewing gum, active dry yeast, frozen convenience foods, prepared cereal products, prepared snacks, dried and processed meat, potato flakes, enriched rice products and shortening.
Butylated Hydroxytoluene (BHT) is also a chemical preservative used in animal feeds and drugs; therefore consumption of non-organic meats and dairy products may be another vector for exposure.
In addition to its use in food preservation, BHA is also used in the manufacture of rubber, tires and petroleum and is an ingredient in some cosmetics.

HOW DOES BUTYLATED HYDROXYTOLUENE (BHT) WORK ?
Butylated Hydroxytoluene (BHT) is an antioxidant.
Butylated Hydroxytoluene (BHT) may damage the protective outer layer of viral cells.
This may keep the viruses from multiplying and/or doing more damage.

USES & EFFECTIVENESS of BUTYLATED HYDROXYTOLUENE (BHT):
Insufficient Evidence for
Cold sores caused by a type of virus called herpes.
Developing evidence suggests that putting Butylated Hydroxytoluene (BHT) on cold sores may help them heal faster.
Genital herpes.
Acquired immunodeficiency syndrome (AIDS).
Other conditions.
More evidence is needed to rate the effectiveness of Butylated Hydroxytoluene (BHT) for these uses.

BENEFITS of BUTYLATED HYDROXYTOLUENE (BHT):
Butylated Hydroxytoluene (BHT) provides several functional benefits, including extending the shelf life of consumable and non-consumable products, preventing rancid odors and taste deterioration, and preserving the chemical integrity of fats and oils.
Butylated Hydroxytoluene (BHT) improves product stability under storage conditions and reduces economic losses due to spoilage.
Its high effectiveness at low concentrations makes Butylated Hydroxytoluene (BHT) a cost-efficient additive.
Butylated Hydroxytoluene (BHT) is a highly effective synthetic antioxidant designed to prevent oxidative degradation in fats, oils, and lipid-containing systems.
Its strong radical-scavenging ability, chemical stability, and compatibility with organic materials make Butylated Hydroxytoluene (BHT) a key additive in food preservation, cosmetics, pharmaceuticals, and industrial formulations.
