Patent EP-0046534-A1 (EP)
Inventor: JUPE CHRISTOPH DR
IPC: C07C39/08
Filed: 1981-08-10
Abstract: A process for the isolation of hydroquinone, pyrocatechol, phenol and carboxylic acid from the reaction mixture containing the same such as one obtained by reaction of phenol with percarboxylic acid is disclosed. The reaction mixture is fed to a first rectification column and subjected to distillation whereby there is obtained a bottoms product containing pyrocatechol, hydroquinone and phenol. The top product is largely condensed and recycled, there being withdrawn from the top of the rectification column a mixture comprising phenol and carboxylic acid. The phenol and carboxylic acid mixture are continuously fed to a second rectification column where carboxylic acid is separated from phenol and substantially pure phenol is withdrawn from the stripping section and/or bottom of the second rectification column.

Abstract: An output voltage of an AC generator (7) is produced through a full-wave rectifier (14) and converted into a digital signal by an A/D converter (16). This digital signal is compared with a reference signal, and in accordance with the difference therebetween, the firing angle of a thyristor (10) is controlled to regulate the field current. Synchronous point detectors (15, 19) detect a synchronous point of the output voltage of the AC generator (7). A microprocessor (17) computes a firing angle of the thyristor (10) in accordance with the difference between the digital signal and the reference signal and produces a signal representing the computed firing angle upon detection of the synchronous point. The thyristor (10) is fired at the firing angle computed by the microprocessor (17).
