应用苯甲醛及其衍生物与胺亚磷酸合成了 1 0种 N-烃基 -N-苄叉基膦酸 ,并应用 73 0紫外分光光度法研究了它们在一定温度下的颜色变化和吸收光谱 .结果表明 ,氮上含有芳环的膦酸产物具有明显的热色效应 ,并且芳醛中含有硝基时产物的颜色加深 .

N alkyl N benzylene phosphonic acid has been synthesized by using benzaldehyde and its derivatives reaction with amine phosphorous acid. Change of colours and absorption spectrum of N alkyl N benzylene phosphonic acid are studied under suitable temperature range by using a 730 UV spectrophotometry.The result shows that the N alkylphosphonic acid containing aromatic cyclo processes obvious thermochromism and when nitro group presents in aromat...
