In this paper,it is studied that how to synthesize dimethyl carbonate（DMC） with carbon dioxide as material and diols as co-productions,as well as how to product epoxy alkanes from olefins.And it is worth mentioning that DMC is a kind of environment-friendly chemical materials. Besides,DMC,instead of toxic phosgene,is used to develop a series of new clean technologies in this article,such as the production process of ethyl（propyl/butyl/pentyl/hexyl/oxtyl）-methyl/ diethyl/dipropyl/dibutyl/dipentyl/dihexyl/dioxtyl carbonates,furazolidone,hydrazine carbonate,methyl phenylamine/ benzylamine carbamates,dimethyl p-phenylenediamine dicarbamate,methyl m-hydroxyl-amine/m-toluidine carbamates,dimethyl 4,4＇-diphenyl methane/ dimethyl 1,6-hexanediamine dicarbamates,alkylamine methyl carbamate,methyl hydrazine,sulfometuron,metsulfuron-methyl,chlorimuron-ethyl etc.This new production technology which made use of carbon dioxide indirectly and replaced the toxic phosgene can promote optimization of chemical industry structure and shape a Green High-tech Fine Chemical Industry Eco-system for producing a series of fine chemical products with carbon dioxide. All the researches discussed above are significant.By the investigations,not only the industrial structure is optimized,but energy conservation also is promoted.
