Solubility of beta-carotene in binary solvents formed by some hydrocarbons with dibutyl ether and 1,2-dimethoxyethane
Experimental results are reported for the solubility of beta-carotene in six binary mixed solvents formed by dibutyl ether with cyclohexane, hexane, and toluene and by 1,2-dimethoxyethane with cyclohexane, hexane, and toluene at 293.15 K. A spectral colorimeter was used for analysis of beta-carotene concentration. The beta-carotene solubility in the pure solvents increases in the order 1,2-dimethoxyethane < hexane < dibutyl ether < cyclohexane < toluene. The solubility data as a function of the binary solvent mass fractions were smoothed by the Myers Scott equation for asymmetric functions.
