摘　　要：In various temperatures, the effects of inorganic acids on the free phenol level in liquefaction products were investigated. In this paper, the free phenol level was used as an indicator to evaluate liquefaction efficiency. Results showed that sulfuric acid was the best among the 4 acids. Under the condition of reaction temperature 150 ~C, reaction time 1.5 h, liquefaction ratio （liquid ! particleboard） 4 and content of sulfuric acid 6%, the free phenol level in the liquefaction products of waste particleboard is 36.95%, and that of original particleboard is 24.27%.In various temperatures, the effects of inorganic acids on the free phenol level in liquefaction products were investigated. In this paper, the free phenol level was used as an indicator to evaluate liquefaction efficiency. Results showed that sulfuric acid was the best among the 4 acids. Under the condition of reaction temperature 150 oC, reaction time 1.5 h, liquefaction ratio (liquid / particleboard) 4 and content of sulfuric acid 6%, the free phenol level in the liquefaction products of waste particleboard is 36.95%, and that of original particleboard is 24.27%.
