Usage And Synthesis
description
Butylated hydroxytoluene (BHT) is a synthetic phenolic compound mainly used as an antioxidant and preservative in the food industry. It is used to prevent the lipid oxidation in oils and fat-containing foods.
BHT toxicity is generally considered as being low.
Since BHT is used in many near consumer products population wide exposure is expected.
Chemical Properties
Butylated hydroxytoluene(BHT) is white or light yellow crystal. BHT has a melting point of 71°C, a boiling point of 265°C, a relative density of 1.048 (20/4°C), and a refractive index of 1.4859 (75°C). Solubility of BHT at normal temperature: methanolll 25, ethanol 25-26, isopropanoll 30, mineral oil 30, acetonee 40, petroleum etherr 50, benzene 40, lard (40-50°C ) 40-50, corn oil and soybean oil 40-50. BHT is insoluble in water, 10NaOH solution, glycerol, and propylenee glycol. BHT is odorless, odorless with good thermal stability.
