Abstract: Production of alkynols and/or alkynediols by reaction of acetylene with aldehydes in a liquid reaction medium in the presence of a heavy metal acetylide as catalyst and in the presence or absence of basic reagents, at least one of the starting materials being introduced in gaseous form. The catalyst is suspended in the liquid medium and during the reaction a portion of the reaction medium is withdrawn and returned at the entry point below the level of the liquid of the gaseous starting material(s) at a speed of 5 to 100 meters per second into the reaction medium and is introduced into a chamber (located in the reaction medium and extending in the direction of the liquid returned) whose inlet opening has a mean diameter from twice to twenty times the mean diameter of the liquid nozzle and whose length is three to thirty times ints hydraulic diameter. The products are important intermediates for example for the production of solvents or may be used in electrolytic baths.
