摘要
为丰富来自生活实际的真实问题情境的实验,以4种常见生活食品(雀巢咖啡伴侣、大白兔奶糖、德芙白巧克力以及家用植物油)为底物,通过各物质配料表分析其存在的常见官能团,运用新制氢氧化铜、碱性水解、碘加成等反应对相应基团进行检验。实验表明,检验现象明显,每种官能团的检验用时都在1 min以内,用量少且过程安全可控。
In order to enrich the experiment of real problem situations from real life,four common foods(Nestle coffee mate,white rabbit toffee,Dove white chocolate and household vegetable oil)were used as substrates.The common functional groups were analyzed through the ingredient list of each substance,and the corresponding groups were tested by the reactions of newly produced copper hydroxide,alkaline hydrolysis and iodine addition.Experiments show that the inspection phenomenon is obvious,the inspection time of each functional group is less than 1 min,the dosage is small,and the process is safe and controllable.
