The volatile compounds produced by pyrolysis of cigarette paper composed of flax pulp and wood pulp (mix ratio 9/1) on addition of various burning chemicals (organic acid salts and phosphates) in helium atmosphere at 650°C were investigated by pyrolysis gas chromatographic analysis.
The volatile compounds in pyrolysis products of cigarette paper with burning chemicals were almost same as those of cigarette paper without additives. A distinct difference in yields of volatile products was observed at 1% addition of burning chemicals.
The following results were obtained. The yields of eight degradation compounds including one unknown compound (crotonaldehyde. No.4, 2-furaldehyde. No.47, 5-methyl-2-furaldehyde. No.69, unknown. No.111, 3-hydroxy-4H-pyran-4-one. No.149, unknown. No.202, 3, 5-dihydroxy-6-methyl-4H-pyran-4-one. No.205 and 5-hydroxymethy1-2-furaldehyde. No.247) decreased, while those of 3 compounds (acetol. No.18, succinaldehyde. No.40 and r-butyrolactone. No.80) increased. These were all carbonyl compounds.
