摘　　要：采用XRY-1C氧弹热量计测定了反式阿魏酸的标准摩尔燃烧焓为-4737.6 kJ/mol,并用萘作标准物验证了仪器的可靠性,萘的标准摩尔燃烧焓的实验测定值与文献值相比其相对误差为0.11%,同时推算出反式阿魏酸的标准摩尔生成焓为-626.65 kJ/mol,为该产品的工艺开发、工程设计和工业化生产提供了相关基础数据。The standard combustion enthalpy of trans-ferulic acid was determined by XRY-1C calorimeter, which was - 4 736.6 kJ/mol under standard condition. The reliability of instrument was tested by naphthalene, the relative error was 0.11% for the comparison between the setimated value and literature value about the standard combustion enthalpy of naphthalene ; the standard fomation enthalpy of trns-ferulic acid was calculated to be - 626.65 kJ/mol, thus providing the basic data for the development of new synthesis method, engineering design and commercial production of trans-ferulic acid.
