“…As shown in Fig. 6 B , they may be targets for addition to peroxyl radicals, like 2,6-di-tert-butyl-4-methylphenol 14,15 , that react quickly yielding quinine compounds, such as o-quinone 1 and 2 Fig. 6 A , that may lead to physiological effects such as adaptation.…”

The solubility of Butylated hydroxyl toluene in aqueous and alcohol solutions were determined at different temperatures (293.15 to 313.15) K. Using Van't Hoff and Gibb's equations, some thermodynamic functions such as Gibbs energy, enthalpy and entropy of dissolution, and of mixing of Butylated hydroxyl toluene in aqueous and alcohol solutions, were evaluated from solubility data. The solubility was greater in butanol and minimum in water. The enthalpies, entropy and Gibb's energy of dissolution were positive for all solvents.

“…Quantitative inhibition of auto-oxidation by various synthetic and natural phenols and organic sulfur compounds has been investigated by many researchers [1][2][3][4][5][6][7][8][9]. Burton and Ingold studied the radical-scavenging activity of various phenolic compounds using the induction period method in a chlorobenzene-styrene system initiated by AIBN, and found that phenolic compounds act as potent chain-breaking antioxidants [1].…”

Abstract:The radical-scavenging activities of two thiols, eight (thio)barbituric acid derivatives and six chain-breaking phenolic antioxidants were investigated using the induction period method for polymerization of methyl methacrylate (MMA) initiated by thermal decomposition of 2,2'-azobisisobutyronitrile (AIBN) and monitored by differential scanning calorimetry (DSC). The induction period (IP) for the thiols 2-mercaptoethanol (ME) and 2-mercapto-1-methylimidazole (MMI) was about half that for phenolic antioxidants. Except for the potent inhibitor 5,5-dimethyl-2-thiobarbituric acid (3), the IP for thiobarbituric acid derivatives was about one tenth of that for phenolic antioxidants. The IP for 1,3,5-trimethyl-2-thiobarbituric acid (1) and 5-allyl-1, 3-dimethyl-2-thiobarbituric acid (7) was less than that of the control, possibly due to inhibition by a small amount of atmospheric oxygen in the DSC container. The ratio of the chain inhibition to that of chain propagation (CI/CP) for the thiols and thiobarbituric acid compounds except for 1, 3 and 7 was about 10 times greater or greater than that for phenolic compounds. A kinetic chain length (KCL) about 10% greater than that of the control was observed for 1, suggesting that 1 had chain transfer reactivity in the polymerization of MMA. The average molecular weight of polymers formed from thiobarbituric acid derivatives is discussed. OPEN ACCESSPolymers 2012, 4 1026
