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-Bromoanisole is the organobromine compound with the formula CH 3 OC 6 H 4 Br. It is colorless liquid with a pleasant smell similar to that of anise seed. It is one of three isomers of bromoanisole, the others being 3-bromoanisole and 2-bromoanisole. It is the precursor to many 4-anisyl derivatives.
Anisole undergoes electrophilic aromatic substitution reaction at a faster speed than benzene, which in turn reacts more quickly than nitrobenzene.The methoxy group is an ortho/para directing group, which means that electrophilic substitution preferentially occurs at these three sites.
2-Bromoanisole is an organobromide with the formula BrC 6 H 4 OCH 3. A colorless liquid, it is one of three isomers of bromoanisole, the others being 3-bromoanisole and 4-bromoanisole . It is a standard coupling partner in metal catalyzed coupling reactions.
2,4,6-Tribromoanisole (TBA) is a chemical compound that is a brominated derivative of anisole. It is one of the chemicals responsible for cork taint. [2] Tribromoanisole is a fungal metabolite of 2,4,6-tribromophenol, which is used as a fungicide. It can be found in minute traces on packaging materials stored in the presence of fiberboard ...

The relationship between water content and equilibrium relative humidity of a material can be displayed graphically by a curve, the so-called moisture sorption isotherm. For each humidity value, a sorption isotherm indicates the corresponding water content value at a given temperature. If the composition or quality of the material changes, then ...
As such, an Ullmann condensation can be employed: an aryl halide is able to react with phenol (or its derivatives) to form a bis-aryl ether in the presence of a copper-based catalyst, such as copper(II) oxide. [7] An Ullmann condensation between p-methylphenolate and bromobenzene in the presence of a copper catalyst to form 4-methyl-1 ...
