Abstract: PROBLEM TO BE SOLVED: To provide a simple method for measuring parameters in a reactor provided with movable stirrers and by which reliable data of pressure distribution and temperature distribution can be obtained even in an actual work field of the movable stirrers. SOLUTION: In the case of a method for measuring parameters in a reactor provided with movable stirrers and containing probes in the inside, at least two probes 2 connected to a sensor signal amplifier 1 through connection cables guided to the movable stirrers are attached to the surface of each movable stirrer and the measurement data obtained by the probes 2 are transmitted to the sensor signal amplifier 1 through the connection cables and from thence, the data are transmitted to an electronic evaluation unit by non-contact inductive signal transmission using a contactless type sensor tap.

Abstract: La invencion se refiere a un metodo para la produccion continua de alcoholes de polieter usando catalizadores DMC, caracterizado en que en una primera etapa en un reactor que opera de manera continua, los oxido de alquileno se agregan a los materiales de inicio H-funcionales y la descarga desde ese reactor se alimenta a una segunda etapa en un reactor que se divide por medio de pisos sellados en secciones, referidos como compartimientos, que se interconectan por medio de conductos externos, la descarga del reactor de la primera etapa de la reaccion pasa a traves de los compartimientos uno despues de otro.

Abstract: The invention provides a process for continuously preparing polyether alcohols using DMC catalysts, which comprises, in a first step, in a continuous reactor, adding alkylene oxides onto H-functional starter substances and transferring the output of this reactor to a second step in a reactor which is divided by closed trays into mutually separate sections, known as compartments, which are connected to one another by external pipelines, in which the output of the reactor from the first step of the reaction passes through the compartments in succession.

Abstract: Process for measuring the parameters in reactors with moving stirrers contained in the inside of the reactors comprises placing at least two probes (2) on the surface of the moving stirrers connected to a sensor signal amplifier by cables located in the stirrer, feeding measured data obtained at the probes to a sensor signal amplifier via a connecting cable, and further feeding to an electronic evaluation apparatus by contact-less signal transmission. An Independent claim is also included for an apparatus for determining the parameters in reactors with moving stirrers.
