Özet

The following phthalic acid dialkyl esters were subjected to UV irradiation (λ_inc = 254 nm at 22 °C or λ_inc = 240-440 nm at 40 °C): phthalic acid di(2-ethylhexyl) ester (DOP), phthalic acid di(n-octyl) ester (DNOP), phthalic acid di(n-decyl) ester (DDP) and phthalic acid dimethyl ester (DMP). In all cases (except DMP) analogous major photoproducts identified by the gas chromatography-mass spectrometry (GCMS) method are formed: 1-alkenes, alkyl alcohols, phthalic acid anhydride, 2-formyl benzoic acid esters and benzoic acid esters. Generally, the quantum yields of decomposition are quite low: φ </0.03. Extension of the linear alcohol chains decreases the stability: φ,(-DMP)<φ(-DNOP)<φ(-DDP). In the absence of O₂, DOP, which contains branches in the alcohol chains, is more stable than the isomeric DNOP containing linear alcohol chains: φ(-DOP) <φ(-DNOP).
