卷烟纸中助燃剂的分离与鉴定

Isolation and Identification of Combustion Improver in Cigarette Paper

摘要: 为了解卷烟纸中助燃剂的种类,采用不含二氧化碳的二次去离水浸提,浸提液加热蒸干,残留物与KBr一起研磨压片进行红外光谱(IR)扫描,再与酒石酸钠、酒石酸钾钠、酒石酸钾和乙酸钾标准样品的IR谱图比对的方法,对3种卷烟纸中的助燃剂进行了分离鉴定。结果显示,所分析的3种卷烟纸样中的助燃剂均为酒石酸钠。

Abstract: The combustion improver in three kinds of cigarette paper were isolated and identified.The paper samples were extracted with twice deionized CO₂-free water.The extracts were heated and dried, then ground together with KBr, compressed into sheet, and identified by comparing its FTIR with that of standard samples of sodium tartrate, potassium sodium tartrate, potassium tartrate, and potassium acetate.The result showed that all of the analyzed combustion improver were sodium tartrate dihydrate (C₄H₄O₆Na₂·2H₂O).
