알루미나 나노산화물이 Nitrendipine 제조 공정에 미치는 영향

Abstract

The alumina nano powders synthesized by levitational gas condensation (LGC) method were applied to catalyst in manufacturing process of Hanzsch reaction for Nitrendipine. The L-tartaric acid on the surface is carried out with participation of carbonyl fragments, O-H, C-H bonds which affects stereo selectivity, yield on the reagents positively. From the analysis of the IR-spectroscopy, the carbonyl fragments, O-H, and C-H bond were created by the catalytic reaction. From the analysis of the IR-spectroscopy, the carbonyl fragments , O-H, and C-H bond were created by the catalytic reaction. The newly created bonds made a chiral center on the final product.
