| titleOfInvention | Process for preparing diamine single-sided condensation products |
| abstract | Disclosed is a preferred process for preparation of diamine single-sided condensation products. The preferred process involves gradually co-feeding stoichiometric amounts of a heterocyclic compound and a diamine compound into an organic solvent in the presence of an alkali carbonate while heating at ≥ 60 DEG C. This preferred process can increase the reaction rate, improve yield, minimize double-sided condensation byproduct, and produce a high-quality product. |
