Function of Dibutylhydroxytoluene:

Dibutylhydroxytoluene is used in foods that contain oil and fat.

Dibutylhydroxytoluene functions as an antioxidant for preventing spoilage of fats and oils in baked goods by binding oxygen molecules.

Oxygen molecules react preferentially with Dibutylhydroxytoluene rather than oxidizing the fats or oils.

In addition, this action preserves food aroma, color, and flavor.

Benefits of Dibutylhydroxytoluene:

According to scientists, Dibutylhydroxytoluene may be able to eliminate the lipid ‘shields’ of external aggressions or make them permeable, enabling antibodies to successfully attack them.

Since it is fat-soluble, Dibutylhydroxytoluene should be taken with a meal that contains some element of fat (vegetable oil, cheese, butter or margarine) in order to improve absorption and bioavailability.

Natural Occurrence of Dibutylhydroxytoluene:

Phytoplankton, including the green algae Botryococcus braunii, as well as three different cyanobacteria (Cylindrospermopsis raciborskii, Microcystis aeruginosa and Oscillatoria sp.) are capable of producing Dibutylhydroxytoluene as a natural product.

The fruit lychee also produces Dibutylhydroxytoluene in its pericarp.

Several fungi (for example Aspergillus conicus) living in olives produce Dibutylhydroxytoluene.

Production of Dibutylhydroxytoluene:

Industrial production:

The chemical synthesis of Dibutylhydroxytoluene 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, Dibutylhydroxytoluene has been prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation followed by hydrogenolysis.

Preparation Method of Dibutylhydroxytoluene:

p-cresol and tert-butyl alcohol are dissolved by heating, and phosphoric acid is used as catalyst to react at a certain temperature.

The reaction product is washed with sodium hydroxide solution to alkaline first, then washed with water to neutral, and finally distilled, recrystallization provides dibutyl hydroxytoluene.

Or isobutylene mixed with cresol and concentrated sulfuric acid, reaction at a certain temperature for a certain time, and the crude product is neutralized, and then the crude product is dissolved in ethanol, adding thiourea, hot filtration, spin drying, obtained by drying.

Reactions of Dibutylhydroxytoluene:

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.

Dibutylhydroxytoluene stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides.

Dibutylhydroxytoluene 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 Dibutylhydroxytoluene or related phenolic antioxidants.

Each Dibutylhydroxytoluene consumes two peroxy radicals.

Properties of Dibutylhydroxytoluene:

Dibutylhydroxytoluene is a grey-white powder, with a slight musky odor.

Dibutylhydroxytoluene is more stable than many other used antioxidants such as tocopherol and therefore offers longer protection.

Dibutylhydroxytoluene has a fairly long shelf life.

Sustainability:

Dibutylhydroxytoluene is a synthetic product, it is made from petrochemical raw materials.

Dibutylhydroxytoluene is poorly biodegradable in the environment.

Because it is an effective antioxidant, Dibutylhydroxytoluene ensures that products last longer, even at a low dose.
