两种烟用助燃剂对卷烟主流烟气中羰基化合物释放量的影响研究

以湿法按不同比例添加助燃剂柠檬酸钾、酒石酸钾钠到烟丝中,研究其对卷烟烟气中挥发性羰基化合物释放量的影响。结果表明：在添加量为2‰-15‰范围内焦油有下降趋势,其中：（1）加入柠檬酸钾,主流烟气中甲醛、丙醛、丙烯醛的释放量依次增加;丙酮的释放量变化不大;巴豆醛、2-丁酮释放量呈下降趋势,但随着添加量的增加,下降趋于零;丁醛的释放量呈先增加后减少的趋势;添加量为8‰时,乙醛释放量达到最低;（2）酒石酸钾钠的加入使得主流烟气中甲醛、丙烯醛、丙醛的释放量增加;乙醛和丙酮的释放量变化不大;巴豆醛、2-丁酮释放量呈下降趋势。

Study on the Effects of Two Combustion Improvers on the Yield of Carbonyl Compounds in Main Stream Smoke

In order to study on the effect of burn additives on selective reduction of carbonyl compounds in mainstream smoke,different amount of potassium citrate and potassium sodium tartrate solution are added into cut tobacco though wet adding method.The results showed that： when the addition rate is in the range of 2 ‰-15 ‰,（1） With the increase of potassium citrate improver,the content of formaldehyde,acrolein and propionaldehyde in mainstream smoke increase while the content of acetone was stable.On the contrary,Crotonal-dehyde and methyl-ethyl-ketone deliveries decreased and the trend of decreasing dropt to zero with the increase of adding amount.Butyraldehyde delivery decreased followed by increasing initially.When the adding amount of potassium citrate was 8 ‰,the delivery of acetaldehyde was the lowest;（2） Adding potassium sodium tartrate into tobacco results in the increasing of formaldehyde,acrolein and propionaldehyde in mainstream smoke.Meanwhile,there was little change in the content of acetone and acetaldehyde deliveries.Further more,Crotonaldehyde and 2-butanone content declined in mainstream smoke.
