三羟甲基乙烷、三羟甲基甲胺及其二元体系变温红外光谱的研究

Study on Infrared Spectra of PG,TAM and Their Binary Systems

利用变温红外光谱技术对多元醇三羟甲基乙烷 ( PG)、三羟甲基甲胺 ( TAM)及其二元体系的固固相变进行了研究 .研究结果表明 ,在一定温度区间内 ,变温红外光谱图中伸缩振动吸收峰的位置、强度、形状均发生了突跃现象 ,并由此可以验证多元醇及其二元体系固固相变的机理 .

The solidsolid phase transition of pentaglycerine (PG),tris(hydroxymethyl)amin-omethane(TAM) and their binary systems was studied by infrared spectra at various temperatures.At the temperature range corresponding to the solidsolid phase transition,the change of -OH stretching and out-of-plane-deformation vibration indicates that the mechanism of solidsolid phase transition of polyalcohols is related to the intermolecular hydrogen honds.
