摘要：
Titanium silicalite-1 (TS-1) films were synthesized on stainless steel plate, glass slide and monolith supports via an in-situ hydrothermal method. Characterization data showed that the formation of TS-1 films was easier on the porous flat support with rough surface such as monolith than on the smooth non-porous supports like glass slide and stainless steel plate. The film on the monolith had the highest uniformity and smallest size of crystals. The catalytic property of monolith-supported film was tested for epoxidation of allyl chloride (ACH) by H2O2 in a fixed bed reactor. Under the condition of a methanol (solvent)/ACH (90%)/H2O2 (30%) ratio of 12:1:1, a LHSV of 1.35 h(-1) and a temperature of 318 K, the conversion of allyl chloride and the selectivity to epichlorohydrin reached 79 % and 51 %, respectively.
