“…The CAO asymmetrical stretching vibration band for pure 1-hexanol at 1057 cm À1 , in the mixture of diethyl succinate and 1-hexanol is weak, and absorption maximum has smaller value. In general, ethers exhibit strong C@O stretching band around 1730 cm À1 , and strong asymmetric CAOAC stretching band around 1100 cm À1 , while alcohols show an easily distinguishable broad intense band due to self-associated molecules, around 3300 cm À1 , and another one, due to CAO stretch, in the 1000-1150 cm À1 region [31].…”

This work focused on the quantitation of methanol as a hydrate inhibitor in crude oil. The novelty is nanoextraction of a polar compound from a complex non-polar matrix and selection of the proper fiber with maximum selectivity, loading percent, and lifetime. This approach not only does not require specific instrumentation, such as multiple columns and selective detectors, but also has eliminated the use of organic solvent and avoids the insertion of water inside the GC columns. The objective is optimization of extraction conditions, GC adjustments, and data processing. Experiments were conducted on the real sample of Iranian offshore crude oil by a carboxen/PDMS fiber via GC equipped with a cross-linked polyethylene glycol column and flame ionization detector. The results revealed that this fiber adsorbed the alcohols among other light non-polar compounds of crude oil. Moreover, the interference effects of ethanol were solved by proper selection of the thermal program. The LOD, LOQ, and linear range of this approach were determined to be 3.9, 12.9, and 14-229 ppm for methanol, respectively. Using the standard calibration and the standard addition methods, the relative errors of 1.6-7.2 and 5.3-14.0% were determined.
