This work reports the synthesis of a new low-dosage kinetic hydrate inhibitor (KHI) based on the ionic liquid C12PyBr (N-dodecyl pyridinium bromide), which was characterized and evaluated in order to determine its inhibition performance. By means of a microwave-assisted reaction scheme, a high-purity product was obtained and the com. product Inhibex 101 (IC) was employed as a comparison reference at 0.1, 0.5,, and 1.0 wt % in aqueous solution to test the inhibition of methane hydrate formation. In this sense, it was discovered that, by using C12PyBr at 0.1 wt %, the formation of methane hydrates was inhibited at a subcooling of 11.2 K and at a concentration one order of magnitude lower than that used with Inhibex 101 to reach the same performance as KHI. This fact could be used as an attractive factor when establishing gas hydrate inhibition plans for offshore and deep-water scenarios. In the experiment, the researchers used many compounds, for example, 1-Dodecylpyridin-1-ium bromide (cas: 104-73-4Application of 104-73-4).
1-Dodecylpyridin-1-ium bromide (cas: 104-73-4) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Pyridine groups exist in countless molecules, and their applications include catalysis, drug design, molecular recognition, and natural product synthesis.Application of 104-73-4
