Aqueous solution comprising (A) in the range of from 30 to 60% by weight of a complexing agent, selected from the alkali metal salts of methylglycine diacetic acid and the alkali metal salts of glutamic acid diacetic acid, (B) in the range of from 1 to 25% by weight of at least one salt of a sulfonic acid or of an organic acid, percentages referring to the total respective aqueous solution.

Aqueous solutions containing a complexing agent in high concentration

Process for the preparation of racemic &#x3b1;-amino acids or of glycine, wherein the corresponding &#x3b1;-hydroxycarboxylic acid, selected from hydroxyacetic acid, lactic acid, malic acid, &#x3b1;-hydroxyglutamic acid, isocitric acid, tartronic acid and tartaric acid, or at least one salt of the corresponding &#x3b1;-hydroxycarboxylic acid is reacted in the presence of at least one heterogeneous catalyst which comprises at least one transition metal, in the presence of hydrogen with at least one nitrogen compound (c), where the nitrogen compound (c) is selected from primary and secondary amines and ammonia.

Process for the preparation of racemic alpha-amino acids

A process for preparing an N-vinyl compound by vinylating a compound having at least one nitrogen atom (referred to hereinafter as compound for short) with acetylene, wherein

Method for the vinylation of amides

The present invention relates to a process for preparing ether carboxylates.

Preparing ether carboxylates

The present invention relates to 5-isopropyl-3-aminomethyl-2-methyl-1-aminocyclohexane (carvonediamine) and to a process for preparation thereof by a) reacting carvone with hydrogen cyanide, b) then reacting the carvonenitrile obtained in stage a) with ammonia in the presence of an imine formation catalyst and c) then reacting the carvonenitrile imine-containing reaction mixture obtained in stage b) with hydrogen and ammonia over hydrogenation catalysts. The present invention further relates to the use of carvonediamine as a hardener for epoxy resins, as an intermediate in the preparation of diisocyanates, as a starter in the preparation of polyetherols and/or as a monomer for polyamide preparation.

5-isopropyl-3-aminomethyl-2-methyl-1-amino-cyclohexane (carvone diamine), and method for the production thereof

The present invention relates to a process for preparing vinyl carboxylates, wherein a carboxylic acid is reacted with an alkyne compound in the presence of a catalyst which is selected from salts of perrhenic acid at a temperature of =250&#xb0; C. The process gives rise to the desired vinyl esters with a high yield.
