Lactams Preparation TRIZ Cases
- Cyclic Lactam Depolymerization Using Ammonium Phosphate Salts
Ammonium phosphate salts enable reactive distillation of polyamide resin to raise cyclic lactam yield while simplifying purification and cutting energy use.
- Ammonium Sulfate Crystallization with Three-Phase Organic Separation
Three-phase evaporative crystallization separates organic impurities into an oily phase, improving ammonium sulfate purity and yield with lower energy use.
