Abstract (en)
[origin: WO2019048276A1] The present invention relates to a method for producing 1,4-butanediol by catalytic hydrogenation of 1,4-butynediol in a reaction zone with hydrogen in the presence of a heterogeneous hydrogenation catalyst, in which method the content of at least one gas in the exhaust gas stream, selected from CO and CH4, is measured and the content of the measured gas in the exhaust gas stream is used for controlling the hydrogenation.
