hermal decomposition behaviours of no woody biomass (straw) and waste plastic (agricultural film) were investigated using TGA．The results showe that the biomass is decomposed at a wider temperature range than plastics, and the transfer efficiency of biomass is lowest because of the high content of ash and fixcarbon．It is exhibited significant synergistic effect created more the light component between biomass and plastic during co-pyrolysis. The kinetic analysis indicates that the pyrolytic processes can be described as first order reactions model, a quite good fitting of experimental data was obtained for all samples studied．The only plastic can be described as the one model, and the only biomass be described as the two consecutive models, than the biomass/plastic co-pyrolysis need be described as the four consecutive models. The activation energies were found to be in the rang of 64.6 ~ 306.6 kJ/mol, and the pre-exponential factors were 1.1×104～3.0×1022. 

The solubility of p-aminophenol in water, ethanol and the mixture of water and ethanol was determined respectively by the test apparatus established in the lab. The experimental water-solubility of p-aminophenol is in good consistency with the literature data, which confirms the reliability of the experimental apparatus and method. Using solubility model and S-H activity coefficient equation, the parameters lij of the solubility equation were obtained by correlating the solubility data. The thermodynamic model of the calculating solubility of p-aminophenol was obtained, which prove to be useful in predicting the solubility of p-aminophenol in the mixture solvent at higher temperature. The correlated solubility model and calculated results are consistent well with the experimental data.
