摘要

Abstract

The promising combustion and emission properties of polyoxymethylene dimethyl ethers (PODE

) are of significant interest. However

the synthesis of PODE

products with desired chain lengths is still a problem facing synthetic PODE

. Herein

a series of unique IL@SBA-16-Cx solid catalysts are prepared by encapsulation of ionic liquids (ILs) within the nanocage of SBA-16 through a silylation method. The structure of the encapsulated catalyst was characterized by UV-vis spectra

Fourier transform infrared (FT-IR)

adsorption-desorption isotherms

Powder X-ray diffraction (XRD)

Transmission electron microscopy (TEM) and Elemental analysis. The encapsulated catalysts show similar catalytic activity to the homogeneous counterparts and display higher selectivity to the targeted PODE

3-5

products than their homogeneous counterparts in the synthesis of PODE

from methanol (MeOH) and trioxymethylene (TOM). The encapsulated catalysts exhibit a superior PODE

3-5

selectivity and could be the promising catalysts for PODE n synthetic reaction.
