Change in lignin content of Japanese cedar with treatment time for different concentrations of sodium oleate or sodium acetate in glycerol at different temperatures. Error bars shows standard deviation (n = 3). Symbols: times, glycerol only; filled circle, 5% C18:1Na at 250 °C; filled square, 10% C18:1Na at 250 °C; filled rhombus, 20% C18:1Na at 250 °C; filled traingle, 20% C18:1Na at 230 °C. Fatty acid sodium soaps are defined in Table 1
