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.
[2] 2,5-Diaminotoluene is commonly used to produce black, drab and warm browns, and shades of blonde and gray hair dyes. [3] 2,5-Diaminotoluene is also known to be used in the production of dyes for textiles, furs, leathers, biological stains and indicators, wood stains, and pigments. Two examples of dyes produced by 2,5-diaminotoluene are Cl ...
Using these models they can measure and test for generalized patterns in the structure of real food web networks. Ecologists have identified non-random properties in the topological structure of food webs. Published examples that are used in meta analysis are of variable quality with omissions.
Ethyltoluene is produced by ethylation of toluene: CH 3 C 6 H 5 + C 2 H 4 → CH 3 C 6 H 4 C 2 H 5. Over typical acid catalysts, this process gives a mixture of the 2-, 3-, and 4- isomers. Using a modified zeolite catalyst, the alkylation is shape-selective for the 4- isomer. [1] 4-Ethyltoluene is subjected dehydrogenation to give 4 ...
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]
For example, cyclohexane and dioxane may be written as C1CCCCC1 and O1CCOCC1 respectively. For a second ring, the label will be 2. For example, decalin (decahydronaphthalene) may be written as C1CCCC2C1CCCC2. SMILES does not require that ring numbers be used in any particular order, and permits ring number zero, although this is rarely used.

4-Toluenesulfonyl chloride (p-toluenesulfonyl chloride, toluene-p-sulfonyl chloride) is an organic compound with the formula CH 3 C 6 H 4 SO 2 Cl. This white, malodorous solid is a reagent widely used in organic synthesis. [2] Abbreviated TsCl or TosCl, it is a derivative of toluene and contains a sulfonyl chloride (−SO 2 Cl) functional group.
