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 N-alkyl-substituted amino-alkynes of formula R1-C IDENTICAL C-CR2R3-NR4R5 comprises the heterogeneous reaction of an alkyne of formula R1-C IDENTICAL CH, a carbonyl compound of formula R2R3C=O and an amine of formula R4-NH-R5 using an unsupported copper catalyst derived from malachite. 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 heterocycle.

Abstract: Preparation of N-hydroxyalkyl -substituted amino-alkynol derivatives of formula (I) involves reaction of an alkyne of formula R1-C IDENTICAL CH (II) with a 1-oxa-3-aza-heterocycloalkane of formula (III) over a heterogeneous catalyst comprising a compound of a first or second transition group metal. R1= H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl, hydroxyalkyl or -CR2R3-N(R4)-A-OH; R2-R4 = H, alkyl, haloalkyl, cycloalkyl, aryl, alkoxy, alkoxyalkyl or hydroxyalkyl; A = 2-5C alkylene (optionally substituted by one or more of alkyl, haloalkyl, aryl, alkoxy, hydroxy and hydroxyalkyl).
