Information

Name dibutyl hydroxy toluene;BHT
Data
Also known as the 2.6-di-tert-butyl - p-cresol, 2,6-di-tert-butyl - 4-methyl phenol. The white crystalline powder or crystalline. Without it, and tasteless. Molecular 230.36. 69.7 ° C melting point. The boiling point of 265 ° C. Water-insoluble, glycerol. Soluble ethanol, benzene, petroleum, oils. The thermal stability. Metal ions react with no coloring. With characteristic single-phenol distillation, steam heating together with volatile.
production methods : the main method used alkylation. A pair of p-cresol, isobutanol as raw material, concentrated sulfuric acid as the catalyst, isobutanol by dehydration into isobutene alumina, silica-cresol into right for alkylation, the resultant reaction of sodium carbonate used to adjust pH to 7-8, washed with ethanol for rough crystal, and then rough guitar crystal goods ethanol recrystallization, the final filtration, drying derived.
purposes : the main antioxidant cosmetics. Animal and vegetable fat antioxidant role of the fine. For cod liver oil, vitamin oil, butter, vegetable oil, may extend the storage period to prevent rancidity metamorphism. Their antioxidant BHA with the same capacity. In high concentrations and warming circumstances, there is no BHA kind of unpleasant smell phenols. BHA more commonly used, and other organic acid or citric acid for synergist. In vegetable oil BHT : BHA : citric acid = 2:2:1.
