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.
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 ...
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.
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. 1,4-Dicyanobenzene is a colorless or white solid with low solubility in water. [1]

They have the formula C 6 H 6–n Cl n, where n = 1–6 is the number of chlorine atoms. Depending on the number of chlorine substituents, there may be several constitutional isomers possible. Monochlorobenzene; Dichlorobenzene. 1,2-Dichlorobenzene; 1,3-Dichlorobenzene; 1,4-Dichlorobenzene; Trichlorobenzene. 1,2,3-Trichlorobenzene; 1,2,4 ...
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]
Marvel Mystery Oil logo. Marvel Mystery Oil is an automotive product of the American Marvel Oil Company, [1] founded by Burt Pierce in 1923. [2] It is used as a fuel additive and oil additive, purportedly to function as a corrosion inhibitor, penetrating oil, transmission leak stopper and seal relubricator, despite a lack of scientific evidence supporting such claims.
