The processes of dimethyl carbonate （DMC） production from carbon dioxide with co-production of diols and epoxide production from olefins are described. DMC,instead of toxic phosgene,is used to develop a series of new clean technologies for the production of fine chemicals,such as ethyl-methyl,diethyl,dipropyl and dibutyl carbonates,furazolidone,hydrazine carbonate,methyl phenylamine and benzylamine carbamates,dimethyl p-phenylenediamine dicarbamate,methyl m-hydroxyl-amine and m-toluidine carbamates,dimethyl 4,4＇-diphenyl methane and dimethyl-1,6-hexanediamine dicarbamates,alkylamine methyl carbamate,methyl hydrazine,isocyanate,PU,PC,sulfometuron,metsulfuron-methyl and chlorimuron-ethyl etc. These new production technologies with the use of carbon dioxide indirectly and with the replacement of toxic phosgene can promote the optimization of chemical industry structure and shape a green high-tech fine chemical eco-industry.
