摘要： The invention relates to a process for preparing .alpha.,.omega.-C.sub.4 -C.sub.20 -alkenols by catalytic monodehydration of .alpha.,.omega.-alkanediols over a catalyst system comprising the combination of aluminum phosphate and barium phosphate. The gas-phase dehydration which occurs over this catalyst at temperatures of from 300 to 500.degree. C. advantageously combines selectivity with a high space-time yield while simultaneously enabling a high throughput over the catalyst.

摘要： An apparatus designed for the batchwise treatment of suspensions comprises a cylindrical reaction vessel (1) which is rotationally symmetric with respect to an axis (4) and within which, in a coaxial arrangement with respect to said axis (4), an insertion member (28') is disposed which includes a grinding cage (31) and the grinding bed formed by grinding balls (25). By means of delivery elements and stirring elements (35, 37) a suspension stream is generated which passes through the grinding bed in the direction of the arrows (28), leaves the insertion member (28') in the upper region thereof via radially oriented orifices (13) and is circulated via the annular chamber (15) of the reaction vessel (1). The reaction vessel (1) is of pressure-tight design, and heterogenous reactions can proceed inside it in vacuum or pressurized mode.

摘要： A continuous process for preparing organomodified polysiloxanes by the transition metal-catalyzed addition of polysiloxanes containing SiH groups onto substances containing C—C multiple bonds, in particular a process for the continuous hydrosilylation of substances containing C—C multiple bonds, which comprises introducing the reactants, in the presence or absence of a homogeneous or heterogeneous catalyst, into a loop-like, heatable and coolable reaction circuit which has a static mixing element and/or a dynamic mixing element to mix starting materials and product formed, leaving the reaction mixture in the reaction circuit until a predetermined degree of conversion has been reached and subsequently transferring the reaction mixture still containing starting materials to a tube reactor to complete the reaction and taking it off via a receiver. In addition, a suitable industrial apparatus for carrying out the process of the invention is described.
