p-DCB is produced by chlorination of benzene using ferric chloride as a catalyst: . C 6 H 6 + 2 Cl 2 → C 6 H 4 Cl 2 + 2 HCl. The chief impurity is the 1,2 isomer.The compound can be purified by fractional crystallization, taking advantage of its relatively high melting point of 53.5 °C; the isomeric dichlorobenzenes and chlorobenzene melt well below room temperature.
There are three distinct chemical compounds which are dichlorobenzenes: . 1,2-Dichlorobenzene or ortho-dichlorobenzene;; 1,3-Dichlorobenzene or meta-dichlorobenzene;; 1,4-Dichlorobenzene or para-dichlorobenzene.
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.
Boiling points, Master List format [ edit ] In the following table, the use row is the value recommended for use in other Wikipedia pages in order to maintain consistency across content.
On the other hand, some constants, such as K f (the freezing point depression constant, or cryoscopic constant), depend on the identity of a substance, and so may be considered to describe the state of a system, and therefore may be considered physical properties. "Specific" properties are expressed on a per mass basis.
1,2-Dichlorobenzene, or orthodichlorobenzene (ODCB), is an aryl chloride and isomer of dichlorobenzene with the formula C 6 H 4 Cl 2.This colourless liquid is poorly soluble in water but miscible with most organic solvents.
