4-Fluorobromobenzene is synthesized via bromination of fluorobenzene in the presence of a Lewis acid catalyst such as iron(III) bromide or aluminium tribromide. [2]4-Bromofluorobenzene is regarded by the Toxic Substances Control Act as a high production volume chemical, that is, a chemical that 1 million pounds (about 500 tonnes) per year is either produced in or imported to the United States.
In contrast, the boiling points of PhF and benzene are very similar, differing by only 4 °C. It is considerably more polar than benzene, with a dielectric constant of 5.42 compared to 2.28 for benzene at 298 K. [ 4 ] Fluorobenzene is a relatively inert compound reflecting the strength of the C–F bond.
Solubility in water. 0.041 g/100 mL Solubility: soluble in diethyl ether, alcohol, CCl 4 miscible in chloroform, benzene, petroleum ether: Vapor pressure: 4.18 mm Hg
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.

4,4’-Difluorobenzophenone is an organic compound with the formula of (FC 6 H 4) 2 CO. This colorless solid is commonly used as a precursor to PEEK, or polyetherether ketone, a so-called high performance polymer. Because PEEK is resistant to attack, it is commonly used in carbon fiber coatings and cable insulation.

Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
