Toluene is widely used in the paint, dye, rubber, chemical, glue, printing, and pharmaceutical industries as a solvent. [38] Nail polish, paintbrush cleaners, and stain removers may contain toluene. Manufacturing of explosives (TNT) uses it as well. Toluene is also found in cigarette smoke and car exhaust.

It is mainly used to manufacture toluene diisocyanate, which is a key raw material in polyurethane chemistry. [4] It is still the starting material used when non-phosgene methods of production of toluene diisocyanate are used. [5] [6] It is also a degradation product of polyurethane materials produced using toluene diisocyanate.
BHT is used as a preservative ingredient in some foods. With this usage BHT maintains freshness or prevents spoilage; it may be used to decrease the rate at which the texture, color, or flavor of food changes. [25] Some food companies have voluntarily eliminated BHT from their products or have announced that they were going to phase it out. [26]
Vapor pressure at 40°C of toluene is 7880 Pa and methylcyclohexane is 10900 Pa while DBT is 0.07 Pa and perhydro-dibenzyltoluene (H18-DBT) is 0.04 Pa. [17] This substance is currently being used as a heat transfer oil, for example, under the trade name Marlotherm SH. [18] Temperatures of approx. 300°C are necessary for dehydrogenation.
o-Toluidine is absorbed through inhalation and dermal contact as well as from the gastrointestinal tract. [19] [13] [20] [21]The metabolism of o-toluidine involves many competing activating and deactivating pathways, including N-acetylation, N-oxidation, and N-hydroxylation, and ring oxidation.
Nicotine Replacement Therapy. Among your NRT options are nicotine pouches and patches. Pouches directly supply low doses of nicotine through oral absorption.
TsOH is most often supplied as the monohydrate, and it may be necessary to remove the complexed water before use. Impurities can be removed by recrystallization from its concentrated aqueous solution followed by azeotropic drying with toluene. [2] TsOH finds use in organic synthesis as an "organic-soluble" strong acid. Examples of uses include:
