A 尾
O4 type lignin dimer was synthesized.- •
Its pyrolysis mechanism was revealed via combined Py-GC/MS experiments and DFT calculations.
- •
C尾
O homolysis is the major reaction at low temperatures.- •
C尾
O homolysis and concerted decomposition co-lead to reactions at medium temperatures.- •
Secondary decomposition reactions take place at high temperatures.
