    摘要: The present invention relates to the synthesis of a novel compound, in which liquid hydrazine and the derivatives thereof react with excess carbon dioxide to enable the carbon dioxide to chemically bond to the hydrazine and the derivatives thereof. To this end, high-pressure carbon dioxide is used to synthesize hydrazine and the derivatives thereof to which the carbon dioxide is bonded in a pure form with no water and no by-product. Furthermore, the present invention provides a method for utilizing the above-described compounds by reacting the compounds with carbonyl compounds.

    摘要: A preparation of aryl carbamates can be achieved readily by carbonylation of an aromatic polyamine compound with diphenyl carbonate (DPC) using a combination of an organic acid and a tertiary amine as a catalyst. Aryl carbamate can be converted into 4,4′-diphenylmethane diisocyanate (MDI) by heating it at about 200 to about 230° C. in a non-polar solvent containing inhibitor such as benzoyl chloride. In another application, trans-ureation of biscarbamates with an amine or mixed amines is found to be extremely facile in a polar solvent such as dimethyl sulfoxide (DMSO) and tetramethylene sulfone (TMS) in absence of any catalyst to make polyurea polymers of high molecular weights. Thus, efficient green-chemistry processes based on biscarbamates in making isocyanate products as well as urea prepolymers, urea elastomers and urea plastics have been developed in all in excellent yields without using reactive phosgene or 4,4′-diphenylmethane diisocyanate separately in the trans-ureation polymerizations.
