Abstract: In a method for testing the thermally induced unbalance of a rotating machine part, in particular the rotor of a turbogenerator, the rotating machine part or the rotor balanced at normal temperature is brought in the demounted state first to nominal rotational speed and held at this, while its temperature is varied and, at the same time, the transient variations in oscillations of the rotating machine part or rotor which are caused are measured. During the test, the rotating machine part or the rotor is surrounded at least partially by a closed heating cell, a cooling medium flows around and/or flows through the rotating machine part or the rotor in the heating cell, and the heating of the rotating machine part or of the rotor takes place essentially due to the flow-dynamic losses arising from the interaction of the rotating machine part or of the rotor with the circulating cooling medium.

Abstract: Urethanes are prepared by oxidative carbonylation of at least one amino compound in the presence of carbon monoxide, oxygen and organic, at least one hydroxyl-group-carrying compound. The carbonylation is carried out in the absence of halogen-containing promoters. The carbonylation is also carried out in the presence of a metal complex catalyst which contains neutral bidentate N-chelate ligands of the (N˜N) type, two monoanionic N,O-chelate ligands of the general type (N˜O)− or tetradentate dianionic chelate ligands (O˜N˜N˜O)2−.

Abstract: The present invention relates to a novel catalyst for producing N-substituted carbamates, the preparation of the catalyst and an improved method for producing N-substituted carbamates from these novel catalysts. The active component of the catalyst is a heteropoly acid and the catalyst support comprises a metal oxide or a metalloid oxide. The catalyst can be used to promote the reaction of carbamate and amine, thereby generating N-substituted carbamates with high yield. In the presence of the catalyst, the reaction conditions are relatively mild, the catalytic activity and selectivity of the reaction are high, and the reaction time is relatively short. Furthermore, the catalyst can be conveniently separated from the reaction system and recycled. therefore, the catalyst can be used to facilitate the further scale-up test and commercial application.

Abstract: The present invention pertains to a novel method for preparing a carbamate, in which the method comprises reacting an aliphatic substituted urea and/or its derivatives, with a hydroxyl group containing compound to obtain a carbamate. In addition, the present invention provides a novel catalyst which is suitable for catalyzing the reaction to form a carbamate, and a method for preparing the novel catalyst. The method of the present invention for preparing a carbamate does not involve the application of carbon monoxide which is toxic, and the reaction conditions are relatively mild with high catalytic activity, high reaction selectivity of the catalyst, and a relatively short reaction time. Furthermore, the catalyst is separated from the reaction system and reused easily, which will facilitates scale up and industrial application.
