摘要: 双酚A和邻苯二甲酰氯芳香酯环状低聚物经硝基笨重结晶得到环状四聚体,利用GPC、MS(FAB)、1HNMR、IR、DSC和元素分析对其结构进行了表征。其晶体结构由广角X射线衍射法确定为正交晶系,晶胞参数为α=0.9676nm,b=0.8699nm,c=2.0859nm.每个晶胞中含有2个环状四聚体分子,晶体密度为1.36g·cm-3,对环状四聚体晶体衍射峰进行了详细的指标化。

关键词: 环状四聚体, 广角X射线衍射, 晶胞参数

Abstract: The polycrystalline powder of the cyclic tetramer based on bisphenol Aand o-phthaloyldichloride has been prepared by recrystallization from nitrobenzene and its crystalstructure has been determined by Wide-Angle X-ray Diffraction( WAXD ).The unit cell is orthorhombic and its dimensions α=0.967 b=0.8699 nm,c=2.0859 nm.Space group belongs to Pmmm,With two tetramers per unit cell, the crystal density is 1.36 g·cm-3.Indices of crystal diffraction peaks are also detailed in the present work.

Key words: Cyclic tetramer, WAXD, Unit cell parameter
