| Abstract: | 7,11,18,21-Tetra-oxa-trispiro5,2,2,5,2,2] hencicosane was prepared by cyclohexanone reaction of 9 pentaerythritol in the presence of non-acid catalysts. Several factors (catalyst, the radio of reactants, and reaction temperature) were discussed. The structure of 7,11,18,21-Tetra-oxa-trispiro5,2,2,5,2,2] hencicosane was examined using FTIR and HNMR.The yield is more than 70%.The compound is a precursor substance for synthesis of poly-ketal-spiro-vic-diether. |
