胆碱-赖氨酸离子液体选择性降低卷烟烟气中的氰化氢和巴豆醛

摘要

为选择性降低卷烟主流烟气中氰化氢（HCN）和巴豆醛的释放量，采用滤嘴减害添加剂模拟测试装置对20种天然氨基酸进行了筛选，优选赖氨酸制备了气相二氧化硅固载的胆碱-赖氨酸离子液体（[Ch][Lys]/SiO2）颗粒材料（0.30~0.20 mm，60~80目），对材料进行了结构表征和减害性能模拟评价，并通过二元复合滤棒形式进行了卷烟应用效果考察和感官质量评价。减害性能测试结果显示：赖氨酸对降低HCN和巴豆醛有显著效果（P0.05）。%In order to selectively reduce the levels of hydrogen cyanide (HCN) and crotonaldehyde (CRA) in mainstream cigarette smoke, 20 natural amino acids were screened with a simulated filtration device to test their toxicant reduction performance as filter additives. Lysine was selected for the synthesis of fumed silica adsorbed lysine ionic liquid ([Ch] [Lys]/SiO2) adsorbent material (60-80 mesh fine particles). The structure of [Ch] [Lys]/SiO2 adsorbent material was characterized, and its toxicant reduction performance was measured. In addition the material was applied to a dual-segment filtered cigarette, and the sensory quality of cigarette smoke was evaluated. The results of toxicant reduction performance test showed that lysine in the filter was effectivein the reduction of HCN and CRA (P0.05).
