Abstract
In this study, manganese dioxide nanoparticles were synthesized in the pores of zeolite 13X by supporting method and its morphology and structure were characterized by SEM, XRD, IR and AAS techniques. Decontamination reaction of 2-chloroethyl ethyl sulfide (a mustard agent simulant) was investigated by GC technique. The results of GC analysis showed that 2-CEES was completely absorbed by Nano-MnO2/Zeolite13X composite after 168 hours and converted to less toxic chemical product. Decontamination products formed via hydrolysis were hydroxyl ethyl ethyl sulfide and ethyl vinyl sulfide. Destruction reaction of DMMP nerve agent simulant via 31P NMR analysis showed that this composite after 36 hours demolished almost 32 percent of nerve agent simulant

Abstract
in the present Research, in order to access new technologies eliminate radioactive contamination have been carried out . The construction and use of exchange resins with high efficiency and efficacy , as a new approach in research and practical method of separation is introduced. This project is one of the most important pieces of 137Cs radioactive decontamination nuclear fission , two new composite entitled as CER.M-PAN ( cerium molybdate - poly acrylonitrile ) and HCFC-PAN ( Cu Hegzacyanoferrat II- poly acrylonitrile ) was prepared their performance was evaluated in terms of continuous and discontinuous . To identify the structure of the synthesized compound , infrared spectroscopy techniques were used. Surface Area and Porosity of adsorbent beads were assayed . In order to increase the efficiency of these two composites , combining them with the PAN were prepared and their stability in different environmental conditions assessed and evaluated . The results suggest that the same efficiency than HCFC-PAN composite composite is CER.M-PAN .

Abstract
Reduction of methoxyketon 1 by NaBH4 gives methoxyketol 2. Allthough acetate and tosylate of this alchohol were not seprated, benzoate ester was isolated. Reduction of ketol 2 by LiAlH4 gives alchohol 4. Ketol 9 does not react with methyl magnesium iodide, but methoxyketon 1 react with both methyl magnesium iodide and phenyl magnesium iodide gives corresponding hydrocarbons. Keton 13 with phenylmagnesium iodide transforms to hydrocarbon 14. Compound 12 and 14 are light sensitive, disposing to light will change each of them to a mixture.
