Your Mendeley pairing has expired. for its intoxicating effect. Some of these symptoms usually disappear when exposure is stopped. Toluene is mainly used as a precursor to benzene via hydrodealkylation: The second ranked application involves its disproportionation to a mixture of benzene and xylene.[19]. In principle it could be prepared by a variety of methods. Nitration of toluene give mono-, di-, and trinitrotoluene, all of which are widely used. As such, its IUPAC systematic name is methylbenzene. [18] Complete hydrogenation of toluene gives methylcyclohexane. The reaction requires a high pressure of hydrogen and a catalyst. While some nonpolar solvents like toluene can partially dissolve it, the most effective chemical for dissolving sulfur is carbon disulfide. Toluene reacts with Potassium permanganate to yield benzoic acid, and with chromyl chloride to yield benzaldehyde (Étard reaction). Please reconnect. Toluene at 86% by volume fuelled all the turbocharged engines in Formula One during the 1980s, first pioneered by the Honda team. Trinitrotoluene is the explosive typically abbreviated TNT. It undergoes sulfonation to give p-toluenesulfonic acid, and chlorination by Cl2 in the presence of FeCl3 to give ortho and para isomers of chlorotoluene. Determination and Correlation of Solubility of Decahydropyrazino[2,3-b]pyrazine in Methanol, Ethanol, and 2-Propanol. These metrics are regularly updated to reflect usage leading up to the last few days. [25], The environmental and toxicological effects of toluene have been extensively studied. Please note: If you switch to a different device, you may be asked to login again with only your ACS ID. [10] In 1841, French chemist Henri Étienne Sainte-Claire Deville isolated a hydrocarbon from balsam of Tolu (an aromatic extract from the tropical Colombian tree Myroxylon balsamum), which Deville recognized as similar to Walter's rétinnaphte and to benzene; hence he called the new hydrocarbon benzoène. People inhale toluene-containing products (e.g., paint thinner, contact cement, model glue, etc.) [11] In 1843, Jöns Jacob Berzelius recommended the name toluin. Toluene is predominantly used as an industrial feedstock and a solvent. Get article recommendations from ACS based on references in your Mendeley library. Similar to many other solvents such as 1,1,1-trichloroethane and some alkylbenzenes, toluene has been shown to act as a non-competitive NMDA receptor antagonist and GABAA receptor positive allosteric modulator. It is a colorless, water-insoluble liquid with the smell associated with paint thinners. [23][24], In the laboratory, toluene is used as a solvent for carbon nanomaterials, including nanotubes and fullerenes, and it can also be used as a fullerene indicator. Toluene , also known as toluol (/ˈtɒljuɒl/), is an aromatic hydrocarbon. Toluene at 100% can be used as a fuel for both two-stroke and four-stroke engines; however, due to the density of the fuel and other factors, the fuel does not vaporize easily unless preheated to 70 °C (158 °F). Jean-Paul Serin, Sophie Jay, Pierre Cézac, François Contamine, Jacques Mercadier, Cédric Arrabie, Jean-Marc Legros-Adrian. The extent of toluene substitution has not been determined. Benzoic acid and benzaldehyde are produced commercially by partial oxidation of toluene with oxygen. [33] In 2005 the European Union banned the general sale of products consisting of greater than 0.5% toluene. [31] Additionally, toluene has been shown to display antidepressant-like effects in rodents in the forced swim test (FST) and the tail suspension test (TST),[31] likely due to its NMDA antagonist properties. Zeitschrift für anorganische und allgemeine Chemie. Chao Yu, Zuo-Xiang Zeng, and Wei-Lan Xue . [22], In Australia in 2003, toluene was found to have been illegally combined with petrol in fuel outlets for sale as standard vehicular fuel. so any of those, like Toluene and benzene etc could be a good option. Toluene is predominantly used as an industrial feedstock and a solvent. Measurement and Correlation of the Solubilities of Sulfur S8 in 10 Solvents. The same conversion can be effected with elemental bromine in the presence of UV light or even sunlight. Because the S 8 rings in solid sulfur are held to other rings by London dispersion forces, elemental sulfur is insoluble in water. Descriptors for Cyclooctasulfur: Estimation of Water–Solvent Partition Coefficients, Solubilities in Solvents, and Physicochemical Properties. Importantly, the methyl side chain in toluene is susceptible to oxidation. Thus, experimental data concerning sulfur solubility in toluene are necessary for the deposit quantification. The methyl group undergoes halogenation under free radical conditions. Gas chromatography (GC) coupled with a flame photometric detector (FPD) in phosphorus mode allows sulfur quantification indirectly. Typical catalysts include cobalt or manganese naphthenates. 2. Hydrometallurgical Treatment of Elemental Sulfur in Spent Catalysts by Aqueous and Nonaqueous Solutions at Low Temperature. In Situ Reactive Assembly of Scalable Core–Shell Sulfur–MnO2 Composite Cathodes. Toluene had also been used in the process of removing the cocaine from coca leaves in the production of Coca-Cola syrup. Quantification of the sulfur deposit is the first step to an experimental study of the phenomenon. [26] In 2013, worldwide sales of toluene amounted to about 24.5 billion US-dollars. Toluene is sometimes used as a recreational inhalant ("glue sniffing"), likely on account of its euphoric and dissociative effects. 0 [8][9], The compound was first isolated in 1837 through a distillation of pine oil by the Polish chemist Filip Walter, who named it rétinnaphte. [32], Toluene is used as an intoxicative inhalant in a manner unintended by manufacturers. It is a mono-substituted benzene derivative, consisting of a methyl group (CH₃) attached to a phenyl group. [14][15][16] Because the methyl group has greater electron-releasing properties than a hydrogen atom in the same position, toluene is more reactive than benzene toward electrophiles. Toluene can be used to break open red blood cells in order to extract hemoglobin in biochemistry experiments. [27] [12] In 1850, French chemist Auguste Cahours isolated from a distillate of wood a hydrocarbon which he recognized as similar to Deville's benzoène and which Cahours named toluène.[13]. Toluene is used as a cement for fine polystyrene kits (by dissolving and then fusing surfaces) as it can be applied very precisely by brush and contains none of the bulk of an adhesive. Nanoparticles. Sulfur-Rich Organic Films Deposited by Plasma- and Vacuum-Ultraviolet (VUV) Photo-Polymerization. Measurement and Correlation of the Solubility of Hexaquonickel(II) Bis(p-toluenesulfonate) in Water + Ethanol Solvents within 288.15–333.15 K. Eric Cloarec, Jean-Paul Serin, Pierre Cézac, François Contamine, Jacques Mercadier, Amélie Louvat, Alejandra Casola Lopez, Patricia Van Caneghem, Rüdiger Forster, and Uttaro Kim . You’ve supercharged your research process with ACS and Mendeley! Solubility of elemental sulfur in pure organic solvents and organic solvent–ionic liquid mixtures from 293.15 to 353.15K. https://doi.org/10.1080/08827508.2019.1634563, https://doi.org/10.1016/j.fluid.2011.09.012, https://doi.org/10.1016/j.supflu.2010.02.010. As of 2007, 24 U.S. states had laws penalizing use, possession with intent to use, and/or distribution of such inhalants. The enthalpies of dissolution Δ Ho of sulfur in toluene, o-xylene, m-xylene and p-xylene were determined to be 27.93 kJ/mol, 27.95 kJ/mol, 26.98 kJ/mol and 27.70 kJ/mol respectively. [35], Except where otherwise noted, data are given for materials in their, Institute for Occupational Safety and Health, National Institute for Occupational Safety and Health, "Toluene Toxicity, Background, Pathophysiology, Epidemiology", "Examen des produits provenant du traitement de la résine dans la fabrication du gaz pour l'éclairage", "Examen des produits provenant du traitement de la résine dans la fabrication du gaz pour l'éclairage,", "Recherches sur les résines. [19], Toluene can be used as an octane booster in gasoline fuels for internal combustion engines as well as jet fuel. Junyoung Kim, Eunho Lee, Sanket Bhoyate, Tae Kyu An. The individual effect of four different imidazolium ionic liquids – 1-butyl-3-methylimidazolium hexafluorophosphate ( [C 4 mim] [PF 6 ]), 1-hexyl-3-methylimidazolium hexafluorophosphate ( [C 6 mim] [PF 6 ]), 1-butyl-3-methylimidazolium tetrafluoroborate ( [C 4 mim] [BF 4 ]), and 1-hexyl-3-methylimidazolium tetrafluoroborate ( [C 6 mim] … Firstly, toluene exhibits a high solubility to sulfur at a high temperature (11.564 g/100 g solvent at 353.15 K) and with a marked decrease at a low temperature (1.979 g/100 g solvent at 293.15 K).
