C. above the boiling point of the lowest-boiling component and (c) the pressure is kept at from p to 100 bar, where p is the vapor pressure of the mixture at the reaction temperature.The products methylpseudoionone, dimethylpseudoionone, pseudoirone, methylpseudoirone and dimethylpseudoirone are useful scents and scent intermediates. In addition, pseudoionone is an important intermediate for the industrial preparation of vitamin A, and 6-methyl-hepta-3,5-dien-2-one is a sought-after aromatic.

The input shaft extends in a longitudinal direction. The drive unit comprises a power-split device, of which the input member is connected to the input element and of which the output members are connectable to driveshafts of the axle. The axle is oriented in a direction transverse to the longitudinal direction.The input member and the output members of the power-split device are mounted rotatably about axes parallel to the longitudinal direction. An angle drive is arranged in each case between the output members of the power-split device and the driveshafts.

    摘要: A drivetrain for a motor vehicle has a friction clutch for transmitting drive torque for the motor vehicle and has an actuator arrangement for actuating the friction clutch. The actuator arrangement has a first actuator which is designed to close the friction clutch quickly with little force expenditure in order to thus quickly close up the play which is present in the open state of the friction clutch. The actuator arrangement has a second actuator which is designed such that, with a small stroke, it applies a large force for actuating the friction clutch in order to keep the friction clutch closed with little energy expenditure.

Local and/or global addresses are assigned to the virtual device K and its virtual subcomponents T1 . . . Tn. These addresses allow a user to perform a component-based navigation and a model-based navigation in different views S1 . . . SN of the system.
