Solubility of Hexamethylenetetramine in a Pure Water, Methanol, Acetic Acid, and Ethanol plus Water Mixture from (299.38 to 340.35) K

The solubility of hexamethylenetetramine in pure water, methanol, acetic acid, and ethanol + water was measured by a synthetic method with temperature ranging from (299.38 to 340.35) K at atmospheric pressure. The laser monitoring observation technique was used to determine the disappearance of the solid phase in a solid + liquid mixture. The results were correlated by a semiempirical Apelblat equation.
