Cetyl palmitate (CP) was thermally synthesized using binary 1-hexadecanol (HD) and palmitic acid (PA) mixture as the starting materials in nitrogen with the absence of any catalyst. The molecule structure, thermal property, thermal stability and reliability of as-prepared cetyl palmitate was studied by H nuclear magnetic resonance (H NMR), Fourier transformation infrared (FT-IR) spectrometer, differential scanning calorimetry (DSC) and thermogravimetric analyzer (TGA), respectively. HNMR and FT-IR confirmed the as-prepared product under 350 °C for 30 min was CP with high purity. According to the DSC measurements, the onset melting temperature and latent heat of fusion for the as-prepared CP was 52.3 °C and 180.9 J/g, respectively. Results showed that the synthesized cetyl palmitate was favorable used as phase change material (PCM) owing to its desirable thermal properties, excellent thermal stability and reliability. Due to the low thermal conductivity of CP, it was impregnating into nickel (Ni) foams with different pore sizes to make CP/Ni foam composite PCMs (CPCMs). Compared with pure CP, thermal conductivity of CP/Ni foam (70, 90, and 110PPI) CPCMs were increased by 1.88, 2.02 and 4.86 times, respectively. The CP/Ni foam CPCMs displayed appropriate thermal properties for latent heat energy storage applications.

用于热能存储的鲸蜡基棕榈酸酯/泡沫镍复合相变材料的简便合成及其热性能

以二元1-十六醇(HD)和棕榈酸(PA)混合物为起始原料，在氮气中不存在任何催化剂的情况下热合成棕榈酸鲸蜡酯(CP)。利用核磁共振氢谱(H NMR)、傅里叶变换红外光谱仪(FT-IR)、差示扫描量热仪(DSC)和热重分析仪(TGA)研究了棕榈酸鲸蜡酯的分子结构、热性能、热稳定性和可靠性。 ）， 分别。HNMR和FT-IR证实350℃下30分钟制备的产物是高纯度的CP。根据 DSC 测量，所制备的 CP 的起始熔化温度和熔化潜热分别为 52.3 °C 和 180.9 J/g。结果表明，合成的棕榈酸十六酯具有良好的热性能、优异的热稳定性和可靠性，非常适合用作相变材料（PCM）。由于CP的导热系数较低，将其浸渍到不同孔径的镍（Ni）泡沫中制成CP/Ni泡沫复合PCM（CPCM）。与纯CP相比，CP/泡沫镍（70、90和110PPI）CPCM的导热系数分别提高了1.88、2.02和4.86倍。CP/泡沫镍 CPCM 显示出适合潜热储能应用的热性能。
