    摘要: The invention relates to a process for preparing aldehydes having five carbon atoms, in which an input mixture containing 10% by weight to 50% by weight of linear butenes and less than 5% by weight of 1-butene is hydroformylated with synthesis gas in the presence of a catalyst system comprising rhodium and at least one bisphosphite ligand, wherein the hydroformylation is effected in a reactor from which, over an operating period, a cycle gas containing at least a portion of the products and unconverted reactants from the hydroformylation is continuously drawn off and partly condensed, and uncondensed components of the cycle gas are recycled into the reactor, and wherein, after the operating period has expired, the hydroformylation is stopped, the reactor is freed of reaction residues and the hydroformylation is restarted. It is based on the problem of making such a process more economically viable. The problem is solved by using a bisphosphite of the formula (1) and/or (2) as ligand, extending the operating period to more than 8000 h, and not separating solid reaction residues out of the reactor during the course of the operating period.

    摘要: A process for continuous preparation of filler-containing rubber powders including mixing a filler suspension and rubber latex in the liquid phase. The liquid mixture is passed through a tube, at least a coagulant is added to the tube and filler-containing rubber particles are precipitated. The liquid mixture is passed through at least one throttle position of variable throttle cross-section provided in the tube. The throttle cross-section is adjusted so that the drop in pressure in the liquid mixture achieved across the throttle position is greater than 0.5 bar.

    摘要: The present invention relates to a VCSEL device comprising an optical gain medium (8) arranged between a first DBR (9) and a second DBR (7). The first and the second DBR form a laser cavity and are designed to allow self-contained lasing in the laser cavity, said second DBR (7) being partially transparent for laser radiation resonating in the laser cavity. An optical element is arranged on a side of the second DBR (7) outside of the laser cavity on the optical axis of the laser cavity. The optical element has a concave surface (5) facing the second DBR (7) and being designed to reflect a portion of laser radiation emitted through the second DBR (7) back into the laser cavity. The ratio R/d of the radius of curvature R of the concave surface (5) and the distance d between the concave surface (5) and the gain medium (8) is in the range between 1 and 2. With the proposed VCSEL device a high power output with an improved mode distribution and mode stabilization is achieved.
