Abstract

The history of pyrolysis equipment, methods, and reactions is narrated in the Introduction. Detailed descriptions of flash vacuum pyrolysis (FVP) (or thermolysis, FVT) apparatus for preparative and spectroscopic (UV, IR, electron spin resonance) purposes with product isolation at 77 K or in Ar matrices at ~10 K are presented. Very low pressure pyrolysis (VLPP), laser pyrolysis, and pulsed pyrolysis (jet flash pyrolysis) are also described together with illustrations of apparatus. The solvent spray flash vacuum pyrolysis (SS-FVP) of liquids or solutions of compounds of low volatility is described together with methods for the addition of solids to a pyrolysis tube, in particular details of pipto-pyrolysis (‘falling solid pyrolysis’). Methods used for catalytic vacuum gas–solid reactions (VGSR) are also summarised.
