- Pyrazine, aldine, C4H4N2 (colourless prisms, M. Pt. 55°, B. Pt. 115°), possesses a basic character (B. 26, 721) and is the mother substance of the ketines, e.g. Ketine or dimethyl-pyrazine, C4H2 (CH3 )2 N2, which is obtained by the reduction of isonitroso-acetone or the condensation of amido-acetone (p. 157; B. 19, 2524; 21, 19).

- Fast pyrolysis of biomass occurs usually at 500-700 °C and high heating rates (e.g. 300 °C min-1) over a short time, e.g. pyrolysis of pine wood samples at 550 °C results in the release of high amounts of aldehydes, ketines and methoxylated phenol.
