The formation of Polycyclic Aromatic Hydrocarbons in the circumstellar outflows ofevolved stars is reviewed, with an emphasis on carbon stars on the Asymptotic GiantBranch. Evidence for PAHs present in their winds is provided by meteoritic studies andrecent observations of the Unidentified Infrared bands. We detail the chemical processesleading to the closure of the first aromatic ring as well as the growth mechanisms leadingto amorphous carbon grains. Existing studies on PAH formation in evolved stellar envelopesare reviewed and new results for the modelling of the inner wind of the archetype carbonstar IRC+10216 are presented. Benzene, C6H6, forms close to thestar, as well as water, H2O, as a result of non-equilibrium chemistry inducedby the periodic passage of shocks. The growth process of aromatic rings may thus resemblethat active in sooting flames due to the presence of radicals like hydroxyl, OH. Finally,we discuss possible formation processes for PAHs and aromatic compounds in thehydrogen-rich R CrB star, V854 Cen, and their implication for the carriers of the RedEmission and the Diffuse Interstellar Bands.
