Abstract: Distillative recovery of alpha -ethynyl-carbinols (I) from the liquid reaction mixture from the addition of acetylene to alpha , beta -unsaturated carbonyl compounds comprises continuous distillation, in which the feed is passed to the middle of the distillation column, most of the water is distilled off at the top as azeotrope with the solvent and (I) is recovered below the feed port.

Abstract: Preparation of hydroxy-alkyl substd. amino-alkyne derivatives of formula R1-C IDENTICAL C-CR2R3-NR4R5 (I) is claimed in reaction by the heterogeneously catalysed reaction of an alkyne of formula R1-C IDENTICAL CH (II), a carbonyl compound of formula O=CR2R3 (III) and an amine of formula H-NR4R5 (IV). R1 = H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl or hydroxyalkyl; R2, R3 = H, alkyl, haloalkyl, aryl or alkoxy; R4, R5 = H, alkyl, haloalkyl, aryl, alkoxy or hydroxyalkyl; or NR4R5 = a 5-6 membered heterocyclic ring; providing that at least one of R1, R4 and R5 = hydroxyalkyl.
