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.

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.
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]
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 ...
Both naphthalene and 1,4-dichlorobenzene undergo sublimation, meaning that they transition from a solid state directly into a gas; this gas is toxic to moths and moth larvae. [1] Due to the health risks of 1,4-dichlorobenzene, and flammability of naphthalene, other substances like camphor are sometimes used.
1,4-Dichlorobutane is a chloroalkane with the molecular formula (CH 2 CH 2 Cl) 2. It is one of several structural isomers of dichlorobutane. They are all colorless liquids of low flammabiltity and of interest for specialized synthetic uses.
