季戊四醇与正碳酸乙酯在260℃下反应12h，得到白色结晶物质，其结构经13C CPMAS核磁共振、CHN分析、FT-IR、电子和X-射线粉末衍射及Rietveld分析表征。发现白色晶体材料具有式C6H8O4和具有单斜晶胞[a=9.167 A，b=5.681 A，c=5.880 A，β=90度，空间群I2]的六方排列螺状低聚物链的晶体结构。
The reaction of pentaerythritol and tetraethylorthocarbonate at 260 degrees C for 12 h yields a white crystalline material that was characterized by 13C CPMAS NMR, CHN analysis, FT-IR, electron and X-ray powder diffraction, and Rietveld analysis. The white crystalline material was found to have the formula C6H8O4 and a crystal structure with a monoclinic cell [a = 9.167 A, b = 5.681 A, c = 5.880 A, beta = 90.0 degrees , space group I2] of hexagonally arranged spiro-oligomeric chains.
