2. 1,4-Dichlorobenzene - Wikipedia

   en.wikipedia.org/wiki/1,4-Dichlorobenzene

   1,4-Dichlorobenzene (1,4-DCB, p-DCB, or para-dichlorobenzene, sometimes abbreviated as PDCB or para) is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2. This colorless solid has a strong odor. The molecule consists of a benzene ring with two chlorine atoms (replacing hydrogen atoms) on opposing sites of the ring.

3. Dichlorobenzene - Wikipedia

   en.wikipedia.org/wiki/Dichlorobenzene

   1,2-Dichlorobenzene or ortho-dichlorobenzene; 1,3-Dichlorobenzene or meta-dichlorobenzene; 1,4-Dichlorobenzene or para-dichlorobenzene. All three isomers are colorless chlorobenzenes with the formula C 6 H 4 Cl 2. They differ structurally based on where the two chlorine atoms are attached to the ring.

4. 1,4-Dichloro-2-nitrobenzene - Wikipedia

   en.wikipedia.org/wiki/1,4-Dichloro-2-nitrobenzene

   Disperse Yellow 42, a popular dye for polyesters, is derived from 1,4-dichloro-2-nitrobenzene. [1] 1,4-Dichloro-2-nitrobenzene is an organic compound with the formula C 6 H 3 Cl 2 NO 2. One of several isomers of dichloronitrobenzene, it is a yellow solid that is insoluble in water. It is produced by nitration of 1,4-dichlorobenzene. It is a ...

   The dichlorobenzene ends up in the urine as dichlorophenol. The toxicology says that it is not very toxic to liver cells. And whyt I find funny is that more than 90% of all americans contain significant amounts of p-dichlorobenzene and some upto 450 microgramm per liter urin.

6. Polyphenylene sulfide - Wikipedia

   en.wikipedia.org/wiki/Polyphenylene_sulfide

   The PPS (polyphenylene sulfide) polymer is formed by reaction of sodium sulfide with 1,4-dichlorobenzene: n ClC 6 H 4 Cl + n Na 2 S → [C 6 H 4 S] n + 2n NaCl Hill and Edmonds, developers of PPS. The process for commercially producing this material was initially developed by Dr. H. Wayne Hill Jr. and James T. Edmonds at Phillips Petroleum. [7]

7. 1,2-Dichlorobenzene - Wikipedia

   en.wikipedia.org/wiki/1,2-Dichlorobenzene

   The 1,3- isomer is uncommon because it is a meta- compound, while chlorine, like all halogens, is an ortho/para-director in terms of electrophilic aromatic substitution. It is mainly used as a precursor to 1,2-dichloro-4-nitrobenzene, an intermediate in the synthesis of agrochemicals. [5] In terms of niche applications, 1,2-dichlorobenzene is a ...

9. Bergman cyclization - Wikipedia

   en.wikipedia.org/wiki/Bergman_cyclization

   When quenched by tetrachloromethane the reaction product is a 1,4-dichlorobenzene and with methanol the reaction product is benzyl alcohol. When the enyne moiety is incorporated into a 10-membered hydrocarbon ring (e.g. cyclodeca-3-ene-1,5-diyne in scheme 2 ) the reaction, taking advantage of increased ring strain in the reactant, is possible ...
