- •
Compactness of coal matrix could be enhanced by AAEMs.
- •
Efficient interactions between solvents and coal could be intensified by acid treatments.
- •
Intensity of HBs O⋯H formed between THF and coal is stronger than that of N⋯H formed between pyridine and coal.
- •
Compositions of extracts strongly depend on solvent types and amounts of AAEMs.
