Toluene is found naturally in crude oil, and is used in oil refining and the manufacturing of paints, lacquers, explosives (TNT) and glues. In homes, toluene may be found in paint thinners, paintbrush cleaners, nail polish, glues, inks and stain removers.

What is another name for toluene?
Also called methylbenzene, phenylmethane.
Why is it called toluene?
The name toluene was derived from the older name toluol that refers to tolu balsam, an aromatic extract from the tropical American tree Myroxylon balsamum, from which it was first isolated.
Why toluene is a good solvent?
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid.
Is toluene toxic to humans?
Toluene is irritating to the skin, eyes, and respiratory tract. It can cause systemic toxicity by ingestion or inhalation. The most common route of exposure is via inhalation.
How is toluene made?
Toluene is produced during petroleum refining operations, directly as a by-product of styrene manufacture and indirectly as a by-product of coke-oven operations. It is produced from petroleum as an aromatic mixture with benzene and xylene primarily by catalytic reforming and pyrolytic cracking.
What can I use instead of toluene?
In formulations where Toluene is present in relatively small amounts, Toluene can be replaced by Methyl Cyclohexane and/or acetates almost as a direct drop in as long as evaporation rates of the final blend are similar.
How do you get toluene?
Toluene is made through catalytic reforming by passing a hydrocarbon mixture over a dehydrogenation catalyst. Hydrocarbon gases are removed, and an aromatic-rich fraction is obtained from the reformate. Toluene is then produced through distillation or solvent extraction (which is the more usual method).
What is the difference between benzene and toluene?
Toluene and benzene are two related organic compounds. Toluene is a derivative of benzene. The main difference between toluene and benzene is the presence of a methyl group in toluene whereas benzene has no methyl groups attached.
Is toluene basic or acidic?
It’s mildly acidic and should be handled with caution because it can cause chemical burns. ) in a mono-substituted benzene derivative. As a result, its IUPAC designation is methylbenzene. Toluene is primarily utilised as a solvent and an industrial feedstock.
Is toluene a drug?
Unlike other central nervous system (CNS) depressant drugs, toluene produces illusions and hallucinations [11, 12]. Of particular concern is that even acute inhalation can lead to life threatening conditions due to poor oxygenation, cardiac arrhythmias and other complications associated with hypokalemia.
What is the strongest solvent?
Butanone. Butanone or MEK is tied with acetone as one of the strongest solvents. This solvent is used as lacquer, varnish, paint remover, denaturing agent for denatured alcohol, glue and cleaning agent.
Does toluene dissolve in water?
Since it is an aromatic compound, its odor is sweet and benzene-like. It is a colorless liquid and has a density of 0.87 g /mL. Its solubility in water is very less or negligible and it is equal to 0.52 g /L at 20∘C which means in one liter of water only 0.52 grams of toluene is soluble.
What can toluene dissolve?
Toluene has been used as an ingredient in nail polish removers, due to its ability to help dissolve other substances, such as resins and plasticizers. It has also been used in the formulation of nail products to enable nail polishes, hardeners and lacquers to be applied smoothly.
What is the smell of toluene?
Toluene vapor has a sharp or sweet odor, which is a sign of exposure. Toluene is typically used in a mixture with other solvents and chemicals such as paint pigments. Products that may contain toluene-such as paint, metal cleaners and adhesives-are used in many industries and can be found in many workplaces.
Does toluene cause death?
Neurological Effects. Chronic toluene abuse in humans has been associated with neurotoxic symptoms, narcosis, permanent damage to the central nervous system, and death.
When was toluene banned?
Toluene has been a part of the industry for years. Other countries such as Europe and the US have banned its use for a number of years and have been able to use other alternative methods of printing. The ban officially became effective July 1st, 2021.
Is toluene organic or inorganic?
Toluene is a common lipid soluble organic solvent used in paints and thinners.
Is toluene in nail polish?
Toluene is used as a solvent in a variety of nail products, including some nail polishes, nail hardeners, and polish removers; however, its use is being phased-out.
Why is toluene used in paint?
As a solvent, toluene is a fast-drying chemical perfect for thinning paints, enamels, varnishes and alkyd resins — although it does have limits due to how strong it is. It is commonly used as a thinner for specialty paints and coatings because it can be too strong for many conventional coatings.
Is toluene a cleaner?
Product Information. It is primarily used to dissolve adhesives and in clean-up applications. Toluene is also used as a finishing clean-up solution for industrial coating applications that include wood, containers, automotive products, machinery manufacturing, and more.
Is toluene and xylene the same thing?
What is the Difference Between Toluene and Xylene? Toluene and xylene are aromatic organic compounds. The key difference between toluene and xylene is that toluene contains one methyl group attached to a benzene ring whereas xylene contains two methyl groups attached to a benzene ring.
Is toluene a green solvent?
Toluene has similar dipolarity to the green solvents, but lacks the coordinating oxygen of the oxolane family of solvents. As shown in Fig. 1, all the tested solvents were found to be suitable media for the reaction since poly(1,4-butylene adipate) was obtained in all cases but with different monomer conversion rates.
Who makes toluene?
ProChem, Inc. Manufacturer of soluble toluene. Physical properties include 111 degrees C boiling point, -95 degrees C melting point and 0.87 g/ml specific gravity.
What does toluene react with?
Chemical properties Importantly, the methyl side chain in toluene is susceptible to oxidation. Toluene reacts with potassium permanganate to yield benzoic acid, and with chromyl chloride to yield benzaldehyde (Étard reaction).
