Method for accelerating the cross-linking process in paints

Higher &agr;,&bgr;-unsaturated alcohols are prepared by monoethynylation of a ketone by the NH /KOH method, if desired hydrogenation of the acetylene alcohol in the presence of hydrogen over a Pd-containing thin layer catalyst, purifying distillation of the hydrogenation product, preferably in a dividing wall column with recirculation of the unreacted ketone to the ethynylation step, and, if desired, preparation of higher alcohols having in each case 5 more carbon atoms in the chain by reacting the alcohols prepared by monoethynylation and, if desired, partial hydrogenation with alkyl acetoacetates diketene in a Carroll reaction to form ketones and using these as starting materials for the steps ethynylation, optional hydrogenation and fractional distillation.

Preparation of higher &agr;, &bgr;-unsaturated alcohols

In a process for isolating &agr;-ethynyl carbinols from the liquid reaction mixture from the addition of acetylene onto &agr;,&bgr;-unsaturated carbonyl compounds by distillation, the distillation is carried out continuously, the feed stream is introduced into the middle section of a distillation column (K), the major part of the water is distilled off azeotropically together with the solvent at the top of the column, and the &agr;-ethynyl carbinol target product is taken off below the feed point to the column.

Butyrolactone-preparation process

A process for preparing N-alkyl-substituted aminoalkynes by reacting an alkyne with a carbonyl compound and an amine with heterogeneous catalysis in which an unsupported copper acetylide derived from malachite is used as the catalyst. The N-alkyl-substituted aminoalkyne have a wide variety of uses including their use as precursors for pharmaceuticals, their use in electroplating processes and their use as corrosion inhibitors.

Preparation with heterogeneous catalysis of N-alkyl-substituted

N-Hydroxyalkyl-substituted aminoalkynes of the formula I ##STR1## are prepared by reacting an alkyne with a 1-oxa-3-azaheterocyclo-alkane in a reaction with heterogeneous catalysis by a catalyst which comprises a compound of a metal of the first or second sub-group.
