ABSTRACT

Experimental results are reported for the solubility of a-carotene in six binary mixed solvents formed by 2,5,8- trioxanonane with 1-hexene, cyclohexane, hexane, and toluene and by 1-hexene with 2-propanone and cyclohexanone at 293.15 K. A spectral colorimeter was used for analysis of a-carotene concentration. The a-carotene solubility in the pure solvents increases in the order: 2-propanone less than hexane less than 2,5,8-trioxanonane less than 1-hexene less than cyclohexane less than cyclohexanone less than toluene. The solubility data as a function of the binary solvent mass fractions were smoothed by the Myers and Scott equation for asymmetric functions. The Flory and Huggins theory of non-athermal mixtures and the Acree and Rytting model were used for prediction of experimental data for the solubility of a-carotene in the six binary above listed mixed solvents.
