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. Some of these symptoms usually disappear when exposure is stopped. 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). Toluene had also been used in the process of removing the cocaine from coca leaves in the production of Coca-Cola syrup. The same conversion can be effected with elemental bromine in the presence of UV light or even sunlight. , The compound was first isolated in 1837 through a distillation of pine oil by the Polish chemist Filip Walter, who named it rétinnaphte. 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. Zeitschrift für anorganische und allgemeine Chemie. , Toluene inhibits excitatory ion channels including the N-methyl-D-aspartate (NMDA) glutamate and nicotinic acetylcholine receptors (nAChRs) and potentiates the function of inhibitory ion channels such as the gamma-aminobutyric acid receptor type A , glycine, and serotonin receptors. Importantly, the methyl side chain in toluene is susceptible to oxidation. For example, elemental sulfur is a solid consisting of cyclic S 8 molecules that have no dipole moment. Nitration of toluene give mono-, di-, and trinitrotoluene, all of which are widely used. , In Australia in 2003, toluene was found to have been illegally combined with petrol in fuel outlets for sale as standard vehicular fuel. Toluene may also be brominated by treating it with HBr and H2O2 in the presence of light.. Stable and high-performance piezoelectric sensor via CVD grown WS 13 publications.  Additionally, toluene has been shown to display antidepressant-like effects in rodents in the forced swim test (FST) and the tail suspension test (TST), likely due to its NMDA antagonist properties. 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). 2. Toluene reacts with Potassium permanganate to yield benzoic acid, and with chromyl chloride to yield benzaldehyde (Étard reaction). It is a mono-substituted benzene derivative, consisting of a methyl group (CH₃) attached to a phenyl group. 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.. Experimental Studies of Solubility of Elemental Sulfur in Methane at 363.15 K for Pressure Ranging from (4 to 25) MPa.  In 2013, worldwide sales of toluene amounted to about 24.5 billion US-dollars. As of 2007, 24 U.S. states had laws penalizing use, possession with intent to use, and/or distribution of such inhalants. The temperature dependences of the solubility of sulfur in toluene, o-xylene, m-xylene and p-xylene were determined from solubility equilibria. These metrics are regularly updated to reflect usage leading up to the last few days. Solubility of Elemental Sulfur in Toluene between (267.15 and 313.15) K under Atmospheric Pressure, High Pressure Processes Group, Department of Chemical Engineering, Laboratoire de Thermique, Energétique et Procédés (LaTEP), Université de Pau, rue Jules Ferry, BP 7511 64075 Pau Cedex, France, and GDF SUEZ, Direction de la Recherche et de l’Innovation, 361 avenue du Président Wilson, 93211 Saint Denis la plaine, France. , Toluene is a common solvent, e.g. Toluene reacts as a normal aromatic hydrocarbon in electrophilic aromatic substitution.
