Heretofore, ethanol has been the most widely used solvent for the recrystallization of cholesteryl esters. In this study of some solubility characteristics of cholestery1 esters,n-pentanol is shown to be a more effective solvent than ethanol in which to remove impurities and/or crystalline structural defects from cholesteryl esters that can cause additional transitions on initial heating.n-Pentanol is shown to be a regular solvent for cholestetryl esters, whereas ethanol is not. This could be a major reason whyn-pentanol is better able to discriminate between compound and impurity than ethanol. Contrary to previous reports, after crystallization fromn-pentanol, in contrast to ethanol, cholesteryl acetate and cholesteryl laurate have only one transition on first heating. A detailed study of cholesteryl benzoate recrystallized fromn-pentanol has confirmed that there are two transitions, one at 146.0 °C. the secpond at 179.6 °C. The heats of transitions are found to be 14.7 cal./gm. and 0.26 cal./gm. respectively.
