【Abstract】 A new isothermal calorimeter without using mercury has been constructed for the measurement of excess enthalpy. This calorimeter has advantages of simple structure,easy manufacture and convenient operation. The data of excess enthalpies for ethanol(1)+hexane (2) have been determined at 298.15k by this calorimeter and give good agreements with the literature data.更多还原
