PROBLEM TO BE SOLVED: To manufacture high purity diphenyl oxalate efficiently, stably and continuously. SOLUTION: There is provided a manufacturing method of diphenyl oxalate including reacting dialkyl oxalate and phenol in the presence of a catalyst and using a compound represented by the following general formula (1) as the catalyst. M(OAr)mRn (1), where M represents one metal of Al, Ti, V, Fe, Zn, Sn and Pb, Ar represents an aryl group having a substituent or an unsubstituted aryl group other than an unsubstituted phenyl group, R represents an alkyl group, m represents an integer of 2 to 4, n represents an integer of 0 to 2, m+n represents a valency of M. M is preferably Ti, Ar is preferably an aryl group having an organic group having 1 to 10 carbon atoms as a substituent, further preferably a phenyl group having the substituent, and especially preferably a phenyl group having an organic group having 1 to 10 carbon atoms as the substituent.

Comparative study on the catalytic properties of amino-functionalized silica materials for the transesterification of dimethyl oxalate with phenol

A series of hybrid mesoporous MCM-41 materials containing different amino groups (such as 3-aminopropyl (AP-), (2-aminoethylamino)propyl (AAP-), or [2-(2-aminoethylamino)ethylamino] propyl (AEP-) group) were prepared by a post-grafting method, and characterized by means of X-ray powder diffraction (XRD), N2 adsorption, Fourier transform-infrared spectroscopy (FT-IR) and temperature-programmed desorption of CO2 (CO2-TPD). The catalytic properties of these hybrid materials were investigated for the transesterification of dimethyl oxalate with phenol. All the samples were active for the transesterification. Among them, the sample AEP-MCM-41 exhibited the highest activity under test conditions. And only a slight decrease in activity could be observed after few runs, indicating the good recyclability of this catalyst. Notably, the activity of the used catalyst could be regenerated by simple treatment with diluted basic agents under mild conditions. Moreover, effects of the density and the basic strength of the amino groups on the catalytic properties were taken into consideration for understanding the reaction mechanism and the possible formation route of the by-product anisole.
