인산 담지 촉매를 이용한 고순도, 고수율의 N-Phenylmaleimide 의 상업적 제조방법 연구

Abstract

This study proposes a high-purity, high-yield synthesis process for N-Phenylmaleimide (N- PMI) using a phosphoric acid-supported catalyst. N-PMI is a key compound in various industries, including polymers, electronics, and medical materials, and is in high demand due to its excellent thermal and chemical stability. However, existing synthesis methods often suffer from low yields or incomplete reaction selectivity, highlighting the need for more efficient synthetic approaches. In this study, we demonstrate that the use of a phosphoric acid-supported catalyst significantly enhances the reaction efficiency for N-PMI synthesis, while also providing optimization conditions for obtaining high-purity N-PMI. Experimental results confirm that the phosphoric acid-supported catalyst can notably improve both reaction selectivity and yield, outperforming traditional methods. Additionally, by analyzing the effects of key reaction parameters (such as temperature, solvent, and catalyst concentration), we have derived the optimal synthesis conditions. Market analysis indicates that the global demand for N-PMI is rising, particularly in the electronics, textile, and medical sectors. Specifically, there is an increasing need for high- purity and high-yield synthesis methods. The phosphoric acid-supported catalyst-based approach proposed in this study offers a promising solution to meet these market demands and is expected to provide a significant technological advantage for future commercial production.
