摘  要:本文通过简便的方法,制备了不同颜色的对环境友好、低毒的彩色火焰蜡烛。采用NaOH溶液对烛芯棉线进行脱脂处理,通过浸泡盐酸和氯化铵的混合溶液对棉线进行脱钠脱钙处理,将处理过的烛芯浸泡在不同的金属盐溶液中进行发色剂吸附,最后将烛芯浸泡在硝酸铵进行氧化促进吸附。烛体采用适量组分的柠檬酸三甲酯、硬脂酸酰胺、硬脂醇和不同的金属盐混合溶液制备。相比于以往的蜡烛制备方法,“干枝”“流泪”等现象都将得到避免,并且蜡烛火焰颜色鲜艳明亮,具有长时间储藏并且不改变其形状等特点。实验进一步设计了自动化烟花、自制七彩蜡烛和焰色反应小实验等互动环节,寓教于乐,形象生动,为化学科普提供了可行性新案例。In this paper,different colors of environment-friendly and low-toxicity colored flame candles were prepared by a simple method.The cotton wick was degreased by NaOH solution,the cotton thread was desodified and decalcified by soaking the mixed solution of hydrochloric acid and ammonium chloride.The treated candle wick was soaked in different metal salt solutions for hair color adsorption,and finally the candle wick was soaked in ammonium nitrate for oxidation accelerator adsorption.The candlestick body was prepared by the mixed solution of trimethyl citrate,stearamide,stearyl alcohol and different metal salts with appropriate components.The candle flame hair color effect is good,eliminate the common“dry branches”,“tears”and other phenomena,and the candle storage time is long,not easy to deformation.The experiment further designed the automatic fireworks,self-made colorful candles and flame color reaction experiment and other interactive links,lively and lively,for chemical science popularization provides a viable new case.
