Exposure to toluene may occur from breathing ambient or indoor air affected by such sources. VOC (Volatile organic compounds) 1 Volatile organic compounds recommended for measurement. The abuse of volatile substances is an important problem in the United States and many other countries around the world . Toluene is produced during the process of making gasoline and other fuels from crude oil, in making coke from coal, and as a by-product in the manufacture of styrene. Disposal. Toluene has many uses, especially as an effective solvent. Tobacco smoke, traffic exposure and solvents used for paints, rubber and adhesives are known sources for these compounds. Toluene is highly volatile and can be present in the air of a workroom as vapour. For the method to be viable for the detection of volatile substance abuse, the chlorination reactions were effected in … It is also produced in the process of making gasoline and other fuels from crude oil and making coke from coal. As nouns the difference between toluene and cyclohexane is that toluene is toluene (liquid hydrocarbon) while cyclohexane is (organic compound) an alicyclic hydrocarbon, c 6 h 12, consisting of a ring of six carbon atoms; a volatile liquid. As a result, water reaches an equilibrium vapor pressure equal to atmospheric pressure (i.e. This condensate will be richer in the less volatile component, toluene, and so the vapor which passes on will be richer in benzene than before. Toluene should be stored indoors in a standard flammable liquids room or cabinet that is separate from oxidizing materials. Toluene is insoluble in water but may be miscible with other organic solvents. Toluene occurs naturally in crude oil and in the tolu tree. Volatile organic compounds, VOCs, comprise generally toxic, low boiling point compounds, including aromatics such as toluene (methylbenzene) and the xylenes (dimethylbenzenes), and aliphatics, such as acetone (propanone) and n-hexane. Toluene. About. Chemical Classification: Hydrocarbons (contain hydrogen and carbon atoms), Volatile organic compounds . The deliberate inhalation of these products can lead to exposure to very high toluene levels. The benzoic acid resulting from toluene and/or ethylbenzene and the two phenylethanols resulting from ethylbenzene were detected by GC-MS as their trimethylsilyl (TMS) derivatives. 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively. Volatile inhalants can exist as liquids that vaporize at room temperature. Tobacco smoke, traffic exposure and solvents used for paints, rubber and adhesives are known sources for these compounds. 108-88-3. Example of a VOC and chlorinated solvent: Toluene (CAS 108-88-3)11 Example: Toluene is commonly used in adhesives and may be found in fabric or leather coatings, fabric inks, synthetic leather and as an impurity in polystyrene-based resins used for button production. Toluene is a volatile solvent that harms the nervous and immune systems, damages the liver and may increase the risk of miscarriage and birth defects. Consider, for example, the vapor pressure of solutions of benzene and toluene of various compositions. It has an aromatic, benzene-like smell and is a highly volatile flammable liquid with a flash point of 4° C. It is obtained from petroleum and coal tar. TOLUENE .

Sources Toluene production worldwide is estimated to be … Solution: 1) Raoult's Law for a solution of two volatiles is this: Toluene is less volatile than other hydrocarbons, but due to its strong smell it's best to store it in closed bottles, and kept in a solvent cabinet. Toluene is a clear, colorless liquid with an aromatic odor. However at one point the vapor-temperature curves for water and toluene cross. Toluene is a dangerous fire hazard and can lead to flashback due to its heavy vapour. Toluene is volatile meaning that it disperses into the air and can thereby be inhaled. 2(b)(i) - Hazardous Agents. The aim of the present study was to investigate whether toluene… Toluene is suspected to cause cancer and it shows reproductive toxicity. CAS: 108-88-3. Contact sales. Data on the extent of this practice are difficult to acquire, but available estimates are likely to be under-representative. Toluene is inexpensive and simple to produce, and is widely used in industrial processes as a solvent. In high doses, it can be toxic. True "Huffing" is a practice of inhaling volatile solvents from old rags soaked in the solvent fluid and held in the mouth. the boiling point) at a lower temperature than toluene. Sources of non-occupational exposure. Storage. It also has a variety of applications in the lab, as well as various industrial uses. Speak to ICIS Toluene is less toxic and carcinogenic than benzene, meaning it can be used as a substitute for benzene as a solvent. Common VOCs include acetone, benzene, ethylene glycol, formaldehyde, methylene chloride, perchloroethylene, toluene and xylene. ... ndecane, tetradecane, n-hexadecane, toluene, o-xylene, cyclohexane, 1-octanol, benzyl alcohol, ethylene glycol, di-ethyl phthalate. The odour threshold varies considerably; a geometric mean of 11 ppm has been estimated from published data (2). Toluene is an aromatic hydrocarbon solvent and natural sources of toluene include crude oil and small quantities it is found in tolu tree.Toluene alternative names include methylbenzene, toluol, anisen, phenyl methane. The central nervous system (CNS) is the primary target organ for toluene toxicity in both humans and animals for acute (short-term) and chronic (long-term) exposures. The benzylic carbon hydrogen bonds of toluene are relatively weak (85 kcal/mol) versus the aryl C-H bonds (110 kcal/mol). A widely used industrial solvent. Toluene, benzene and styrene are volatile organic compounds (VOCs) widely distributed in the environment. Toluene … Mother’s exposure to toluene vapors during pregnancy may cause developmental damage in the fetus. What are the mole fractions of benzene and toluene, χben and χtol in both the liquid and vapor phases above a mixture where the total vapor pressure is P tot = 82.0 torr?. Solvent: Toluene is a common solvent in paint, thinners, adhesives, and nail polish, as well as numerous other products. Toluene Diisocyanate is a synthetic mixture of the 2,4- and 2,6-isomers is a volatile, colorless to pale yellow liquid that is soluble in many organic solvents. Due to its ability to cross the blood brain barrier and affect the central nervous system, it is an important chemical in everyday substances that can induce as sense of euphoria among other neurological disruption. Read More. Toluene (C 7 H 6), also known as methylbenzene, is a colourless liquid, with a strong, solvent-like smell. Toluene … As a result at that point toluene is more volatile and will evaporate more quickly. Toluene. Toluene is a clear water-insoluble solvent with a molecular formula of C 7 H 8, CAS: 108-88-3. Different VOCs have different health effects, and range from those CAD - Chemical Agents Directive. Toluene is a petroleum-derived chemical found in gasoline and used as a solvent in paints, adhesives and cleaning supplies. 3) is a noncorrosive, volatile liquid with an aromatic odour. When a vapor reaches the bottom-most glass beads en route to the condenser, part of it will condense. Its solubility in water is 535 mg/litre (1). Toluene. At room temperature, toluene is both volatile and flammable. It is an irritant to the eyes, skin, nose and lungs. A volatile petrochemical solvent and paint thinner, toluene is a potent neurotoxicant that acts as an irritant, impairs breathing, and causes nausea. Toluene is added to gasoline, used to produce benzene, and used as a solvent. Organic volatile impurities are residual solvents that are used in and are produced during the synthesis of drug substances, or in excipients used in the production of drug formulations. | Explore the latest full-text research PDFs, articles, conference papers, preprints and more on TOLUENE.
