| titleOfInvention | Retarderer for Hydrate-forming binder |
| abstract | Process for the preparation of a setting retarder for hydrate-forming binders, wherein a) a first reactant A, comprising an amino acid and / or an amino acid derivative, with b) a second reactant C, comprising an amine-free carboxylic acid and / or an amine-free carboxylic acid derivative, is converted to a reaction product, characterized in that the reaction at a pH of 7.5 - 1 1 .5 and the pH during the Conversion is kept constant in the specified range 7.5 - 11.5. In order to keep the pH constant in the specified range and to avoid fluctuations, an aqueous solution of reactant A is initially introduced in one process step and by addition of base a pH of 7.5 to 11.5, preferably 8 to 11, in particular 8.5 - 1 0.5, set. In a second process step, partial amounts of the base and partial amounts of the reactant C are added in order to stabilize the pH during the reaction. |
