BHT (3,5-di-tert-butyl-4-hydroxytoluene) Is a widely used antioxidant in polymers as well as in many other applications. The solubilities of BHT In various solvents, such as n-heptane, ethanol, water, ethanol/water mixtures, 1-octanol, and corn oil, have been determined. The solubility of BHT in n-heptane Is found to be slightly less than the ideal solubility predictable from calorimetric constants of BHT. Equilibrium absorption of BHT by several polyolefins have also been determined. Partition coefficients of BHT between solvents and polymers as derived from the solubility and absorption data are compared and discussed with partition coefficients observed from extraction and migration experiments. © 1985, American Chemical Society.
