| titleOfInvention | METHOD FOR PRODUCING AMINOMETHYLATED PHENOL DERIVATIVES |
| abstract | The invention relates to a process for the preparation of aminomethylated phenol derivatives from secondary amines, formaldehyde, and phenol or its derivatives. Such phenol derivatives are preferred as corrosion inhibitor components. used as a hardener for epoxy resins and as catalysts in polyurethane chemistry. The aim and object of the invention are to eliminate the disadvantages resulting from the use of additives and super stoichiometric amounts of secondary amine and formaldehyde in the manufacturing process and produce aminomethylated phenol derivatives by changing the technological conditions materialoeconomically advantageous in high space-time yield with minimal wastewater pollution , According to the invention, aminomethylated phenol derivatives are obtained in accordance with the object and problem if the preparation is carried out in the absence of solvents or inorganic salts, without excess of secondary amine and formaldehyde and using products enriched in distillation from the aqueous phase. Such products enriched in distillation, with a water content of 2 to 70%, are expediently to be added to the secondary amine initially introduced. |
