In this paper,we use the maximum absorbance of 3,5-Diacetyl-1,4-dihydro-2,6-dimethylpyri-dine in 412 nm,exert the good characteristic of Hantzsch reaction with formaldehyde,take the gas analysis method to determine the degree of formaldehyde pollution.
利用二乙酰基二氢二甲基吡啶(DDL)在412nm处具有最大吸光度,运用汉茨(Hantzsch)反应对甲醛所表现出来的良好特性,采用气体分析法测定样品中甲醛的含量进而分析新装修后居室的污染情况,结果表明,气体分析法是一种快速便捷的测定新装修后居室的甲醛含量的方法,其灵敏度高。
