Solubility of triclosan and iodopropynyl butylcarbamate in pure alkanols at several temperatures

Solubility data for triclosan and iodopropynyl butylcarbamate (IPBC) in ethanol, 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, and 1-heptanol were measured. Solid–liquid phase equilibrium measurements were conducted at several temperatures (from 278.15 to 318.15 K). After drying the equilibrium saturated solutions, gravimetric measurement was used to determine experimental solubility. The data were correlated using a equation for the solubility of a solid in a liquid and the nonrandom two liquid (NRTL), universal quasi-chemical (UNIQUAC) and Wilson models for activity coefficients. The data are well fitted with all three models for the six pure alcohols studied here.
