Abstract: The present invention relates to processes for making 1,4-butanediol, 1,4-butenediol, or a mixture thereof by processing 1,4-butynediol in a dynamic mixing apparatus in an inert gas atmosphere at from 25 to 150° C. at a shear rate in the radial gap between rotor and stator of the mixing apparatus of more than 100 000 sec-1; phase separating the processed 1,4-butynediol at a temperature of from 25 to 150° C.; removing a bottom phase to obtain purified 1,4-butynediol; and reacting the purified 1,4-butynediol with hydrogen in the presence of a catalyst.
