Determination of jet fuel system icing inhibitor by GCxGC-FID was written by Vozka, Petr;Kilaz, Gozdem. And the article was included in Talanta in 2020.Electric Literature of C5H12O3 This article mentions the following:
Jet fuel usually contains a small amount of dissolved H2O, which can sep. out at high altitudes and low temperatures This can bring along serious clog issues as H2O can freeze in fuel pumps, lines, or filters; blocking the fuel flow which can even cause engine shut down. To prevent such a disaster, an additive called fuel system icing inhibitor (FSII) is added to jet fuels. The amount of FSII is regulated in both civil and military jet fuels by pertinent standards A method for quantification of FSII: diethylene glycol monomethyl ether (DiEGME) by comprehensive 2-dimensional gas chromatog. with flame ionization detector (GC x GC-FID) was developed. The method allows the determination of DiEGME from a very small quantity of samples (0.5μL) and is very fast with a mean absolute error of 0.001 volume% and a correlation coefficient of 0.9997. The DiEGME content (at 0.07-0.12 volume%) in 23 fuel samples was analyzed via GC x GC-FID. The accuracy of the proposed method was evaluated by the ASTM standard D5006. The procedure that uses a refractometer, outlined in D5006, is currently the only available standard for determining the DiEGME concentration in fuel. Results were within the repeatability of the D5006 method (0.009 volume%). Since the D5006 method is accepted as an accurate technique for DiEGME content determination, the GC x GC method proposed in this study can be considered precise and accurate. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Electric Literature of C5H12O3).
2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Electric Literature of C5H12O3
