摘要： The invention relates to a method for producing an isocyanate, wherein a carbamate or thiolcarbomate is converted, in the presence of a catalyst, with separation of an alcohol or thioalcohol, at a temperature of at least 150° C., to the corresponding isocyanate, wherein a compound of the general formula (X)(Y)(Z—H) is used as a catalyst, in particular characterized in that the compound has both a proton donor function and a proton acceptor function. In the catalysts according to the invention, a separable proton is bound to a heteroatom, which is more electronegative than carbon. Said heteroatom is either identical to Z or a component thereof. In the catalysts according to the invention, there is additionally a proton acceptor function which is either identical to X or a component thereof. According to the invention, the proton donator and proton acceptor function are connected to each other by the bridge Y.

摘要： A method and a continuous process for producing two isocyanates by reacting a first amine with phosgene in a stoichiometric excess in the gas phase to produce a first isocyanate. The excess phosgene is subsequently recovered and recirculated back to react with a second amine to produce a second isocyanate. In an embodiment, both fresh and recycled phosgene may be used in reacting each respective amine to produce an isocyanate. The amine streams contain two different concentrations of hydrogen chloride: one may be between 0.0 and 0.1%, and another may be between 1 and 5% by weight.

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.
摘要翻译：通过使用有机酸和叔胺的组合作为催化剂使芳族多胺化合物与碳酸二苯酯（DPC）羰基化，可以容易地实现氨基甲酸芳基酯的制备。通过在含有非极性溶剂的抑制剂如苯甲酰氯中将其加热至约200至约230℃，将氨基甲酸芳酯转化为4,4'-二苯基甲烷二异氰酸酯（MDI）。在另一个应用中，发现在不存在任何催化剂的情况下，在极性溶剂如二甲基亚砜（DMSO）和四亚甲基砜（TMS）中，使用胺或混合胺转化双氨基甲酸酯非常容易地制备高分子量的聚脲聚合物重量因此，在制备异氰酸酯产物以及尿素预聚物，尿素弹性体和尿素塑料中基于双氨基甲酸酯的高效绿色化学方法已经以优异的产率开发，而不用在反式碳酸酯中分别使用反应性光气或4,4'-二苯基甲烷二异氰酸酯，脲化聚合。
