The fruit lychee also produces Antioxidant BHT in its pericarp.
Several fungi (for example Aspergillus conicus) living in olives produce Antioxidant BHT.
Production of Antioxidant BHT:
Industrial production:
The chemical synthesis of Antioxidant 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, Antioxidant BHT has been prepared from 2,6-di-tert-butylphenol by hydroxymethylation or aminomethylation followed by hydrogenolysis.
Preparation Method of Antioxidant BHT:
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 Antioxidant 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.
Antioxidant BHT stops this autocatalytic reaction by converting peroxy radicals to hydroperoxides.
Antioxidant 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 Antioxidant BHT or related phenolic antioxidants.
Each Antioxidant BHT consumes two peroxy radicals.
Properties of Antioxidant BHT:
Antioxidant BHT is a grey-white powder, with a slight musky odor.
Antioxidant BHT is more stable than many other used antioxidants such as tocopherol and therefore offers longer protection.
Antioxidant BHT has a fairly long shelf life.
Sustainability:
Antioxidant BHT is a synthetic product, it is made from petrochemical raw materials.
Antioxidant BHT is poorly biodegradable in the environment.
Because it is an effective antioxidant, Antioxidant BHT ensures that products last longer, even at a low dose.
