N2 - In this study, the influence of organic liquids on microwave (MW) pyrolysis of cellulose was investigated. MW-related solvent parameters were separated into three main groups which could be characterise as i) MW-solvent, ii) solvent-cellulose and iii) solvent-product interactions. The characterisation of MW-solvent interaction was performed by measuring the dielectric loss factor (ϵ'') of selected solvents using the resonant cavity perturbation (RCP) technique. The solvent-cellulose interaction was measured by the degree of cellulose swelling. The solvent-product interaction was evaluated with Abraham solvation parameters by using Multilinear regression (MLR) and PCA analysis. The MW heating rate was analysed with nonlinear regression and the efficiency of solventcellulose interaction in MW was found to correlate with the mass balance of products. MLR of cellulose swelling and solvation parameter was found to be independent of each other. A relation between McGowan volume of solvent with pyrolysis rate of cellulose was revealed.
