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: 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.

Abstract: Process for the preparation of bis(4-hydroxyphenyl) sulphone by reaction of phenol with sulphuric acid in the presence of a solvent at a temperature of 130 to 220 DEG C and, where appropriate, in the presence of a sulphonation auxiliary, the bis(4-hydroxyphenyl) sulphone which is formed being deposited during or after the reaction selectively on a nucleus-forming surface, and being removed from the reaction medium.
