Abstract:n-Alkanes were measured by GC-MS in six types of rice straw grown in China and the smoke generated in flaming and smoldering conditions. The mean content of n-Alkanes in the straw was 73.0μg/g, and the carbon number ranged from C12 to C37, exhibiting the distribution with only one peak at C29. Besides, it had an obvious odd to even carbon number predominance for C23 to C37, and the mean CPI value was 2.9. However, the average n-alkane contents were 1633.1 and 5458.5μg/g in flaming and smoldering smoke, respectively. The carbon number varied from C14 to C35, and showed a single peak distribution at C29 or C31. In addition, the odd to even carbon number predominance was shown for C27 to C35, and the average CPI values were 1.5 and 1.9, respectively. Prominent distinction exists between the composition of n-Alkanes in the rice straw and the smoke.
