Abstract656)      PDF (1962KB)(312)      
Ionic liquid (IL) is a type of molten salt at room temperature which are composed of anions and cations. It is a novel kind of green solvent and catalyst with excellent performance. However, it is 1imited to be widely used in different fields because of high price, large dosage, inconvenient separation. One of the effective approaches is to immobilize the ionic liquid on inorganic or organic solid material. Supported perrhenate ionic liquid was prepared using MCM-41 zeolites as carrier by chemical method in this paper. The supported ionic liquid was characterized and analyzed by FT-IR, TG, XRD and nitrogen adsorption desorption. The results showed that the ionic liquid was successfully bonded to the surface of MCM-41, and the decomposition temperature of the supported ionic liquid was between 280~680 ℃. Although the pore size and specific surface area of MCM-41 decreased after loading IL, its bulk structure was not damaged.

Abstract404)      PDF (2735KB)(212)      
 
Constructing the safety and security city is another innovation of safety control in the last three years. It needs comprehensive and systematic effort to construct the safety and security city. There are a number of large and mediumsized cities which have carried out the plan. In this paper, a preliminary exploration for the meaning and contents of the safety and security city, urban safety planning method, and the index system of safety and security city was conducted, and the composition of the index system of safety and security of urban safety plan and the main index calculation method was focused. The results had the important significance to the construction of safety and security city, scientific evaluation of city security state.
