在1‐甲基‐2‐吡咯烷酮溶剂中，邻苯二酸酐与苯胺反应，得到了二苯基氨基二甲酸二羰基苯与1‐甲基‐2‐吡咯烷酮的配合物1/4 M和1/2 M。通过热重分析、差示扫描量热法、傅里叶变换红外光谱法、偏光显微镜和气相色谱/质谱法研究了该二酸的分解和亚酰化。讨论了与亚胺形成相竞争的副反应。发现溶剂的存在对亚胺化有显著影响。
Complexes between diphenylcarbamido‐dicarboxybenzene and 1‐methyl‐2‐pyrrolidinone, 1/4 and 1/2 M, are obtained by reacting pyromellitic dianhydride with aniline in the solvent 1‐methyl‐2‐pyrrolidinone. Decomplexation and imidization of this diamic acid are studied by thermogravimetric analysis, differential scanning calorimetry, Fourier transform infrared spectrometry, polarizing microscopy, and gas chromatography/mass spectrometry. Side reactions competing with the imide formation are discussed. The presence of solvent is found to markedly influence imidization.
