摘要: A process and apparatus for the measurement of parameters in reactors having moving stirrers which contain probes in the reactor interior, wherein at least two probes connected via a multiplexer to a sensor signal amplifier by connecting cables located in the moving stirrers are installed on the surface of the moving stirrers, and the measurement data obtained by the probes are passed via the connecting cables to a sensor signal amplifier and from thence are passed on to an electronic evaluation unit by non-contact, inductive signal transmission by means of a contactless sensor tap.

摘要: A process for the preparation of bis(4-hydroxyphenyl)sulfone by reacting phenol with sulfuric acid in the presence of a solvent at from 130.degree. to 220.degree. C. and in the presence or absence of a sulfonating assistant, wherein the bis(4-hydroxyphenyl)sulfone formed is selectively deposited on a nucleating surface during or after the reaction, and thus removed from the reaction medium.
