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.
The three xylene isomers: o-xylene, m-xylene, and p-xylene In organic chemistry, xylene or xylol (from Greek ξύλον (xylon) 'wood'; [1] [2] IUPAC name: dimethylbenzene) are any of three organic compounds with the formula (CH 3) 2 C 6 H 4.
As a powerful anticholinergic agent, BZ produces a syndrome of effects known as the anticholinergic toxidrome: these include both psychological and physiological effects, with the most incapacitating effect being a state of delirium characterized by cognitive dysfunction, hallucinations, and inability to perform basic tasks.
The United States Drug Enforcement Administration (DEA) maintains lists regarding the classification of illicit drugs (see DEA Schedules).It also maintains List I of chemicals and List II of chemicals, which contain chemicals that are used to manufacture the controlled substances/illicit drugs.
The C 4-benzenes are a class of organic aromatic compounds which contain a benzene ring and four other carbon atoms. There are three tetramethylbenzenes, six dimethylethylbenzenes, three diethylbenzenes, three isopropylmethylbenzenes, three n-propylmethylbenzenes and four butylbenzenes.
It is produced by dehydrogenation of diethylbenzene: C 6 H 4 (C 2 H 5) 2 → C 6 H 4 (C 2 H 3) 2 + 2 H 2. Divinylbenzene is usually encountered as a 2:1 mixture of m- and p-divinylbenzene, containing also the corresponding isomers of ethylvinylbenzene. Styrene and divinylbenzene react to form the copolymer styrene-divinylbenzene, S-DVB or Sty-DVB.
Toluene (/ ˈ t ɒ l. j u iː n /), also known as toluol (/ ˈ t ɒ l. j u. ɒ l,-ɔː l,-oʊ l /), is a substituted aromatic hydrocarbon [15] with the chemical formula C 6 H 5 CH 3, often abbreviated as PhCH 3, where Ph stands for the phenyl group.
In organic chemistry, a diethynylbenzene dianion is an anion consisting of two ethynyl anions as substituents on a benzene ring. With the chemical formula C 6 H 4 C 2− 4, three positional isomers are possible, differing in the relative positions of the two substituents around the ring:
