영문 초록

Nicotinamide Complex Compound was not formed in simple alkaline solution under two to one molar ratio of dimethylglyoxime and Fe(II), but it was formed with ammonia or pyridine under the same molar ratio. Based on this fact, nicotinamide solution was added into dimethylglyoxime-Fe(II) complex solution, and the chelation product was extracted with chloroform. The extraction was Completed in a range of pH 8.4-11.0. The chloroform solution shows stability and maximum absorption at 516mmc.
