目的 研究活性炭对薄荷醇的封装和热释放性能影响，为活性炭用于加热不燃烧烟草制品的加香提供依据。方法 利用红外光谱(ATR–FTIR)、热重分析(TGA)和扫描电镜(SEM)分析活性炭对薄荷醇的封装性能，并采用热裂解气相色谱/质谱联用法(Py–GC/MS)分析350 ℃温度下活性炭中薄荷醇的热释放性能。结果 活性炭表面有众多的小孔，对薄荷醇有强的封装性能。薄荷醇被活性炭封装后，热稳定性明显提高，最大挥发峰从195 ℃提高到251 ℃，薄荷醇在350 ℃温度下热裂解产物组分少，主产物仍然是薄荷醇，相对质量分数为82.879%。结论 活性炭能够有效封装薄荷醇，延缓其释放速度，达到保香的效果。在加热不燃烧烟草制品的温和加热状态下，活性炭封装的薄荷醇具有良好的热稳定性和可释放性，活性炭可以作为薄荷醇的封装剂用在加热不燃烧烟草制品中。

The work aims to study the effects of activated carbon on the package and heat release properties of menthol. The package property of activated carbon on menthol was analyzed by ATR-FTIR, TGA and SEM, and the thermal release property was analyzed by Py-GC/MS. The results showed that there were many small holes on the surface of activated carbon, which had strong package property on menthol. After the menthol was packaged with activated carbon, the thermal stability of menthol was significantly improved, and the maximum volatile peak increased from 195 ℃ to 251 ℃. The menthol had few pyrolyzates at 350 ℃. The main product was menthol with a relative content of 82.9%. The above results show that activated carbon could effectively package menthol, delay its release rate and achieve the effect of preserving fragrance. The menthol packaged with activated carbon has good stability and release properties under mild heating condition of heat-not-burn tobacco products. Activated carbon can be used as an adsorbent of menthol in heat-not-burn tobacco products.
