Abstract
A compound 3,9 diphenyl 2,4,8,10 tetra oxa spiro undecane was prepared by reaction of benzaldehyde with pentaerythritol in presence of macro-porous resin or molecule sieve.Such reaction conditions as catalyst type,reactant mole ratio,water-carried agent and temperature were determined.The structure of 3,9 diphenyl 2,4,8,10 tetra oxa spiro undecane were examined using FTIR and HNMR.The yield is above 88%.The compound is a precursor substance for synthesis of poly acetal spiro vic diether which is advanced paints and.liquid crystals.
