摘要

Abstract

Surface organometallic chemistry (SOMC) is a recently developing research field. It is of great significance for the quantitative modification

restoration of solid surface

identification of the physical and chemical nature of surface and the preparation of new catalyst. The production of R

Snl-O-MCM-41 (R

SnlM) was obtained by heating tributyltin chloride and Al-MCM-41 mixture at 170℃ for 5 h under stirring in nitrogen atmosphere. The composition

structure and surface physical and chemical properties of the samples were characterized by inductively coupled plasma mass spectrometry (ICP-MS)

. The results of ICP and organic elemental analysis shows that the grafting yield

was 6.46% for R

SnlM.

TEM analysis showed that R

SnlM with ordered hexagonal mesopore structure

resulted in the decease of surface areas and pore size as well as the increase of mesoporous volume and su

as compared to Al-MCM-41. R

SnlM was used in the synthesis of isoamyl acetate. The yield of isoamyl acetate was 96% when
