Caracterização de fenóis no bio-óleo da pirólise de caroço de pêssego por GC/MS e GC×GC/TOFMS

In this paper it was analyzed the bio-oil produced by pyrolysis of peach endocarp using 1D-GC/qMS (onedimensional gas chromatography coupled to mass spectrometry) and GC×GC/TOFMS (comprehensive two dimensional gas chromatography coupled to time of flight mass spectrometry). Were tentatively identified 51 compounds by 1D-GC/qMS and 207 compounds by GC×GC/TOFMS. The chemical classes identified in both techniques were alcohols, aldehydes, anhydrides, ketones, esters, ethers and phenols. However, the class of carboxylic acids, hydrocarbons and sugar derivatives were identified only
