By means of FT-IR analysis of adsorbed pyridine and analysis of XRD, it could be concluded that synergism of interlayer structure with acid sites of Ti-PILC is the dominated factor for the synthesis of DPC by transesterification of DMC with phenol.

• 吸附吡啶的IR光谱和XRD表征表明,Ti-PILC的层柱状结构和酸中心协同作用是催化苯酚和DMC酯交换合成DPC的重要因素。
