Solubility Measurements of Fatty Acid Glucose and Sucrose Esters in 2-Methyl-2-butanol and Mixtures of 2-Methyl-2-butanol with Dimethyl Sulfoxide

Abstract

Solubility measurements of fatty acid esters of glucose and sucrose in pure 2-methyl-2-butanol and mixtures of 2-methyl-2-butanol with dimethyl sulfoxide are presented. For glucose esters the increase of the fatty acid chain length from C8 to C12 leads to an about 3-fold solubility decrease in 2-methyl-2-butanol at 30 °C and 60 °C, while a slight increase is observed for sucrose monoesters. The presence of dimethyl sulfoxide increases the solubility of the esters in 2-methyl-2-butanol. Sucrose dilaurates were 4-fold more soluble than the corresponding monoesters in 2-methyl-2-butanol and in the mixture of 2-methyl-2-butanol with dimethyl sulfoxide.
