“…147 Trained sensory panels were used to determine the odor detection thresholds of two commercial naphthenic acid preparations and naphthenic acid extracted from oil sands. 147 Analysis of the three naphthenic acid preparations by gas chromatography-mass spectrometry showed that each had a unique distribution of acids. 147 And apparently these differences affect their odors because the sensory panel found large differences between the odors of the tested samples.…”

“…147 Analysis of the three naphthenic acid preparations by gas chromatography-mass spectrometry showed that each had a unique distribution of acids. 147 And apparently these differences affect their odors because the sensory panel found large differences between the odors of the tested samples. 147 Odors of naphthalene, l-methylnaphthalene, 2,6-dimethylnaphthalene, 2,3,5-trimethylnaphthalene, 1,4-dimethylbenzene, benzothiophene, dibenzothiophene, and 2,5-dimethylphenol were analyzed as possible fish tainting substances.…”

“…2,5,7 A cromatografia gasosa acoplada à espectrometria de massas (GC/MS -gas chromatography/mass spectrometry) é uma técnica analítica amplamente utilizada para amostras petroquímicas, embora ainda sejam necessárias etapas de isolamento e derivatização dos compostos mais polares.…”

“…[2][3][4][5][6] O termo naftênico, correspondente a compostos cíclicos saturados, é usado para todos os tipos de ácidos encontrados em petróleos, mesmo os saturados lineares e os ramificados. 2,5,7 Os ácidos carboxílicos presentes no petróleo representam um grande problema para o refino e craqueamento do mesmo, devido ao seu efeito corrosivo em linhas de transferência de massa e calor, nas seções de entrada e refluxo de colunas (à pressão atmosférica e a vácuo) e nos condensadores das unidades de destilação das refinarias. 5 De forma geral, determina-se o teor de ácidos através da titulação com KOH, obtendo-se então o índice ou número de acidez naftênica.…”
