Thermal decomposition of cigarette paper. VI. Low boiling composition in pyrolysis products of cigarette paper composed of flax and wood pulps on addition of burning chemicals.

Low boiling compounds produced by pyrolysis of cigarette paper composed of flax pulp and wood pulp (mix ratio 9/1) in helium atmosphere at 650°C were investigated by pyrolysis gas chromatographic analysis. Various organic acid salts and phosphates were added to the cigarette paper as burning chemicals (1, 3 and 5%).The following results were obtained. Low boiling 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 low boiling products was observed at3% addition of burning chemicals. The yields of four degradation compounds (propyne+allene. No.8, acetoaldehyde. No.12 and furan. No.20) decreased.
