Study on Infrared Spectra of PG, TAM and Their Binary Systems
摘要/Abstract
摘要:
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.
Abstract:
The solid solid phase transition of pentaglycerine(PG),tris(hydroxymethyl)amin-omethane(T AM) and their binary systems was studied by infrared spectra at various temperatures.At the temperature range corresponding to the solid solid phase transition,the change of—OH stretch-ing and out-of-plane-deformation vibration indicates that the mechanism of solid solid phase transi-tion of polyalcohols is related to the intermolecular hydrogen honds.
