This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Diethylbenzenes arise as side-products of the alkylation of benzene with ethylene, which can be described as two steps. The first step is the industrial route to ethylbenzene, which is produced on a large scale as a precursor to styrene. C 6 H 6 + C 2 H 4 → C 6 H 5 C 2 H 5. The diethylbenzene is an inadvertent side product. C 6 H 5 C 2 H 5 ...
As benzene is ubiquitous in gasoline and hydrocarbon fuels that are in use everywhere, human exposure to benzene is a global health problem. Benzene targets the liver, kidney, lung, heart and brain and can cause DNA strand breaks and chromosomal damage, hence is teratogenic and mutagenic. Benzene causes cancer in animals including humans.
tert-Butylbenzene can be produced by the treatment of benzene with isobutene [1] or by the reaction of benzene with tert-butyl chloride in presence of anhydrous aluminium chloride, [2] the latter is depicted below:

Its structure consists of a benzene ring para-substituted with a methyl group and an isopropyl group. p -Cymene is insoluble in water, but miscible with organic solvents . Isomers and production
1,4-Dicyanobenzene is an organic compound with the formula C 6 H 4 (CN) 2.Two other isomers exist, phthalonitrile and isophthalonitrile.All three isomers are produced commercially by ammoxidation of the corresponding xylene isomers.
