The melting point, heat of melting, decomposition temperature and other properties of trans-ferulic acid were experimentally studied by differential scanning calorimetry and thermogravimetric analysis method, and the conditions for the determination of trans-ferulic acid by DSC-60 differential scanning calorimeter were determined, that is, under the conditions of a heating rate of 10°C·min-1 and a nitrogen flow rate of 20 mL·min-1, the sample could be analyzed to obtain a more accurate DSC curve, and under these conditions, the melting point of trans-ferulic acid was 174.64 °C and the heat of melting was 150.00 J·g-1. The decomposition temperature was 190 °C. Under the condition of nitrogen atmosphere, the DTA-TGA spectrum of ferulic acid was determined by DTG-60 differential thermal-thermogravimetric analyzer, and there was significant weight loss between 190 °C and 260 °C, which confirmed that ferulic acid began at 190 °C in nitrogen atmosphere
