摘要:

阳离子多孔淀粉是一种新型化学改性淀粉，将其添加到卷烟过滤嘴中可用于吸附主流烟气中的小分子醛类。以玉米淀粉为原料制备玉米多孔淀粉，以3-氯-2羟丙基三甲基氯化铵为醚化剂，采用碱催化干法制备阳离子多孔淀粉，考察了醚化剂与多孔淀粉的质量之比、NaOH与醚化剂质量之比、反应温度及反应时间对取代度和反应效率的影响，优化出最佳条件如下：醚化剂与多孔淀粉质量之比0.04，NaOH与醚化剂质量之比2.0，反应温度80 ℃，反应时间4 h。将阳离子多孔淀粉添加到卷烟过滤嘴中考察其对卷烟主流烟气中巴豆醛的吸附效果，结果表明添加10 mg多孔淀粉的烟支中巴豆醛质量分数降低了14.94%，而添加10 mg阳离子多孔淀粉的烟支中巴豆醛质量分数降低了37.36%。

Abstract:

Cationic porous starch was a new chemical modified starch which can be used as adsorbent in cigarette to absorb crotonaldehyde in mainstream of smoke. The preparation of cationic porous starch was carried out by alkali catalytic under dry process via the reaction of porous corn starch with 3-chloro-2-hydroxypropyl-trimethyl ammonium chloride. Different preparation conditions were investigated based on the degree of substitution （DS） and reaction efficiency （RE），including the mass ratio of etherifying agent/starch and sodium hydroxide/etherifying agent，temperature and reaction duration. The reaction conditions were optimized with 0.04 and 2.0 of the mass ratio of etherifying agent/starch and sodium hydroxide/etherifying agent was at 85 ℃ for 4 h. The results showed that a 37.36 % reduction of crotonaldehyde in cigarette smoke with 10 mg cationic porous starch and only 14.94 % reduction with 10 mg porous starch.
