| titleOfInvention | Production of n,n-diethylaminophenols |
| abstract | PURPOSE: To obtain a compound useful as an intermediate for dye for heat- sensitive and pressure-sensitive papers, xanthene based dye, etc., in high quality and yield, by subjecting aminophenols to reduction and alkylation reaction with acetaldehyde. n CONSTITUTION: Aminophenols are subjected to reduction and alkylation reaction with acetaldehyde in a solvent such as methanol in the presence of a catalyst (e.g. platinum) under hydrogen pressure at ordinary temperature W 150°C. Then unreacted acetaldehyde and solvent are removed while maintaining distillation temperature to ≥160°C from the reaction liquid obtained by separating the catalyst. Then the distillation liquid is distilled while maintaining the liquid to ≤200°C to provide the aimed product. The reaction is carried out using 2.1W4 times mol. acetaldehyde based on 1mol. aminophenols. The aimed compound is advantageously obtained without accompanying problem such as corrosion on material, large amount of drainage and generation of sludge. n COPYRIGHT: (C)1988,JPO&Japio |
