Abstract
he purpose of this study was to determine the stability and structure on the interaction between β-carotene compounds with methanol, ethanol, acetone, chloroform, carbon tetrachloride, cyclohexane, and n-hexane compounds. This research is a molecular modeling using computational chemistry calculations with the function/basis set RHF/3-21G and B3LYP/3-21G. The computational chemistry calculations used Gaussian 09 Revision D 01 and visualization used the Jmol and Avogadro software. The data obtained from computational chemistry calculations with the function/ basis set RHF/3-21G on the interaction between β-carotene -methanol compounds are ∆E = -11.899 kJ / mol, β-carotene -ethanol ∆E = -12.256 kJ/mol, β-carotene -acetone ∆E = -9.276 kJ/mol, β-carotene -chloroform ∆E = 5.262 kJ/mol, β-carotene -carbon tetrachloride ∆E = 3.747 kJ/mol, β-carotene-cyclohexane ∆E = 2.691 kJ/mol, β-carotene-n-hexane ∆E = 6.453 kJ/mol. The data obtained with the function/basis set B3LYP/3-21G on the interaction between β-carotene-methanol compounds are ∆E = -24.588 kJ/mol, β-carotene -ethanol ∆E = -25.123 kJ/mol, β-carotene -acetone ∆E = -18.140 kJ/mol, β-carotene -chloroform ∆E = 2.255kJ/mol, β-carotene -carbon tetrachloride ∆E = -1.187 kJ/mol, β-carotene-cyclohexane ∆E = -0.801 kJ/mol, β-carotene -hexane ∆E = -0.412 kJ/mol. Based on the analysis of thermodynamic data from computational chemistry calculations with the function/basis set UHF/3-21Gand B3LYP/3-21G, it was found that β-carotene-ethanol and β-carotene-methanol mixtures had very stable mixtures.
