Toluene is also found in cigarette smoke and car exhaust. If not in contact with air, toluene can remain unchanged in soil or water for a long time. [39] Toluene is a common solvent, e.g. for paints, paint thinners, silicone sealants, [40] many chemical reactants, rubber, printing ink, adhesives (glues), lacquers, leather tanners, and ...

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 ...
The 2,6 and 3,5 isomers do not form acceptably from toluene or chlorotoluenes, so these isomers are prepared by indirect methods. For example, 2,6-dichlorotoluene can be prepared by chlorination of 4-toluenesulfonyl chloride followed by desulfonation .
In its chemical structure, a molecule of cresol has a methyl group substituted onto the ring of phenol. There are three forms of cresol: ortho-cresol (o-cresol), meta-cresol (m-cresol), and para-cresol (p-cresol).
Levothyroxine, a drug used to treat hypothyroidism, can lead to reduced bone mass and density in older adults with normal thyroid levels, a small cohort study has shown.
