摘　　要：利用傅里叶变温红外光谱仪分别测定了三羟甲基甲胺 (TAM)、季戊四醇 (PE)及其二元体系变温红外光谱。实验表明 ,多元醇分子中羟基吸收峰随温度升高而发生位移向高波数移动 ,此结果既能反映多元醇及其二元体系固 -固相变的温度区间 ,又与转变热相对应 ,从而揭示了多元醇及其二元体系固 -固相变贮热的机理。Fourier infrared spectrometer was used to obtain a series of infrared spectra at various temperatures of tris(hydroxymethyl)aminomethane(TAM), Tetrakis (hydroxy methyl)methane and their binary mixtures. The result shows that the peak position of OH absorption is shifted to high wavenumber with the increase of temperatures.It corresponds the heat of transition. The more wavenumbers shift, the more transition heat. Also,the shift of OH absorption peak indicates the mechanism of solid\|solid phase transitions of polyhydroxy alcohols and their binary mixtures.
