4-Fluoroaniline can be prepared by the hydrogenation of 4-nitrofluorobenzene. [2] It is a common building block in medicinal chemistry and related fields. [3] For example, it is a precursor to the fungicide fluoroimide or the fentanyl analogue parafluorofentanyl. It has also been evaluated for the production of ligands for homogeneous catalysis ...
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.

Toluene (/ ˈ t ɒ l. j u iː n /), also known as toluol (/ ˈ t ɒ l. j u. ɒ l , - ɔː l , - oʊ l / ), is a substituted aromatic hydrocarbon [ 15 ] with the chemical formula C 6 H 5 CH 3 , often abbreviated as PhCH 3 , where Ph stands for the phenyl group.
Many different solvents are suitable, including sulfolane (C 4 H 8 O 2 S), furfural (C 5 H 4 O 2), tetraethylene glycol (C 8 H 18 O 5), dimethylsulfoxide (C 2 H 6 OS), and N-methyl-2-pyrrolidone (C 5 H 9 NO). Below is a schematic flow diagram of one method, involving extractive distillation, for extraction of the BTX aromatics from a catalytic ...
Fluoroaniline may refer to three compounds with the formula FC 6 H 4 NH 2: 2-Fluoroaniline; 3-Fluoroaniline; 4-Fluoroaniline This page was last edited on 9 ...
4-Fluoronitrobenzene can be hydrogenated to give 4-fluoroaniline, [3] which is a precursor to the fungicide fluoroimide and parafluorofentanyl. Owing to the presence of the electron withdrawing nitro group , the fluoride is a good leaving group in fluoronitrobenzenes.
