Abstract:
The invention relates to a method for the amination of at least one keto group in a multicyclic ring system comprising at least one keto group into an amino group, using at least one enzyme E having transaminase activity.
Abstract:
The subject of the invention is a biotechnological process for the production of ω-functionalized carboxylic acids and of ω-functionalized carboxylate esters from simple carbon sources.
Abstract:
A method and a measurement system are specified for localizing at least one wheel on a motor vehicle. In this case the operating situation of the motor vehicle and the wheel load of the at least one wheel and/or a variable dependent on this is determined. Then the at least one measured value of the wheel load is compared with a value assigned to the operating situation. As an alternative or in addition, the comparison of at least one parameter dependent on at least two measured values can be undertaken with at least one of the parameters assigned to this operating situation. Finally the point on the motor vehicle at which the wheel is mounted is determined on the basis of the comparison results.
Abstract:
The present invention relates to a chemocatalytic liquid-phase process for the direct one-stage amination of alcohols to primary amines by means of ammonia in high yields using a catalyst system containing at least one transition metal compound and a xantphos ligand.
Abstract:
The invention relates to O/W wax dispersions based on water, an emulsifier and a wax phase containing predominantly aliphatic hydrocarbons and polar compounds having chain lengths of at least 18 carbon atoms, and also plaster compositions comprising the O/W wax dispersion, and the use of the O/W wax dispersion.
Abstract:
The present invention relates to a process for preparing primary amines comprising the process steps A) provision of a solution of a primary alcohol in a fluid, nongaseous phase, B) contacting of the phase with free ammonia and/or at least one ammonia-releasing compound and a homogeneous catalyst and optionally C) isolation of the primary amine formed in process step B), characterized in that the volume ratio of the volume of the liquid phase to the volume of the gas phase in process step B is greater than 0.05 and/or in that process step B is carried out at pressures greater than 10 bar.
Abstract:
The invention provides a biocatalytic process for oxidation of organic compounds with the aid of an alkL gene product, and microorganisms used in this process.
Abstract:
A motor drive includes a device for safe fitting of the motor drive with a circuit breaker. In at least one embodiment, the device includes a first cover, whose position can be altered, for example by being guided in slotted links, in such a way that only the receiving opening provides a free space for receiving the handle, owing to the overlap by the first cover, and therefore it is only possible for the circuit breaker to be fitted on the motor drive when the handle is in the corresponding position.
Abstract:
The invention relates to compositions based on 2,5-diisocyanato-1,4:3,6-dianhydro-2,5-dideoxy-D-manitol (I), 2,5-diisocyanato-1,4:3,6-dianhydro-2,5-dideoxy-D-glucitol (II), and/or 2,5-diisocyanato-1,4:3,6-dianhydro-2,5-dideoxy-L-iditol (III), alone or in any mixtures.
