在 4 0 0 0～ 4 50 cm- 1波段范围内测定了三羟甲基甲胺 ( TAM)在 2 0～ 1 4 0℃的红外光谱 .研究发现 ,在1 3 0～ 1 3 5℃区间内 ,TAM的特征吸收峰的位置、形状、强度均发生较大变化 ,该温度区间与 TAM的固 -固相变温度1 3 4 .73℃相对应 .研究结果可以验证 TAM的固 -固相变机理
The infrared spectra of TAM at 20 ~ 140 ℃ were measured in the range of 400 ~ 400 cm-1. It was found that in the range of 130 ~ 153 ℃, , The location, shape and intensity of the characteristic absorption peak of TAM changed greatly, which corresponded to the solid-solid phase transition temperature of 1334.73 ℃ .The results of this study can be used to verify the solid-solid phase Change mechanism
