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.

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
3,4-Dichloroaniline is an organic compound with the formula C 6 H 3 Cl 2 (NH 2).It is one of several isomers of dichloroaniline.It is a white solid although commercial samples often appear gray.
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]
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.
The first step is the liquid- or vapour-phase chlorination of butadiene to a mixture of 3,4-dichlorobut-1-ene and 1,4-dichlorobut-2-ene (both isomers). In the second step, the mixture of 1,4-dichlorobut-2-ene and 3,4-dichlorobut-1-ene is isomerized to 3,4-dichlorobut-1-ene by heating to temperatures of 60–120 °C in the presence of a catalyst.
