原油馏分的表面膜暴露于来自不同光源的照射。描述了物理行为。分离并鉴定了降解产物。它们主要是脂族和芳族酸，并且在较小程度上是醇和酚。酸被转化为它们的甲酯，并通过气相色谱和质谱联用进行鉴定。表面膜中的氧化产物的量通过用“衰减全反射”（ATR）红外光谱法测量1700 cm-1区域中的CO-红外吸收来估计。原始原油馏分和降解产物之间的比较导致在自然环境条件下的分解率的估计。
Surface films of a crude-oil fraction were exposed to irradiation from different light sources. The physical behaviour is described. Degradation products were isolated and identified. Primarily they are aliphatic and aromatic acids and to a lesser extent alcohols and phenols. Acids were converted into their methylesters and identified by combined gas chromatography and mass spectrometry. The amount of oxidation products in the surface film was estimated by measurement of the CO-infrared absorption in the 1700 cm−1region with “Attenuated Total Reflection” (ATR) infrared spectroscopy∗. Comparison between the original crude-oil fraction and degradation products lead to an estimation of the decomposition rate under natural environmental conditions.
