摘要
室温下,二氮氧喹喔啉甲醛-γ-羟基丁酰腙()和二氮氧喹喔啉甲醛-水杨酰腙()分别在非水溶剂二甲亚砜(DMSO)中和KOH反应,转变成酰腙烯醇式负离子而显色。和的显色溶液分别在550nm和480nm波长处有最大吸收。从两种显色溶液的比色分析结果得到两个一元线性回归方程。酰腙的溶液:A=0.00225C-0.0080,r=0.999;浓度在7.500—300×10-4mg/mL范围符合比耳定律;酰腙的溶液:A=0.0563C-0.019,r=0.999;在1.00—30.0×10-3mg/mL的浓度范围符合比耳定律;此项研究为酰腙类化合物提供了一种较为方便的定量分析方法。
Di-N-oxoquinoxaline formaldehyde γ-hydroxylbutyric acylhydrazone Ⅰ and di-N-oxoquinoxaline formaldehyde salicylic acylhydrazone Ⅱ react with KOH in DMSO at room temperature within 5min, and give out colored products with absorbing peaks at 550nm and 480nm respectively. The Beer law is obeyed with regression equations, Acylhydrazone Ⅰ： A = 0.00225C-0.0080, r=0.999, in the range of 7. 50-300×10^-6mg/mL, Acylhydrazone Ⅱ ： A=0.0563C-0.019, r=0.999, in the range of 1.00-30.0×10^-3mg/mL. The method is suitable for quantitative analysis of acylhydrazone compound.
