  3. 4-Fluoroaniline - Wikipedia

    en.wikipedia.org/wiki/4-Fluoroaniline

    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 ...

    en.wikipedia.org/wiki/Azeotrope_tables

    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.

  6. 4-Fluoronitrobenzene - Wikipedia

    en.wikipedia.org/wiki/4-Fluoronitrobenzene

    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. Thus reaction with phenoxide gives the mononitrodiphenylether. [4]

    en.wikipedia.org/wiki/R-410A

    Alternative refrigerants are available, including hydrofluoroolefins, R-454B (a zeotropic blend of R-32 and R-1234yf), hydrocarbons (such as propane R-290 and isobutane R-600A), and even carbon dioxide (R-744, GWP = 1). [4] [15] [16] [17] The alternative refrigerants have much lower global warming potential than R-410A. Some alternatives have ...

    Fluorinert is the trademarked brand name for the line of electronics coolant liquids sold commercially by 3M.As perfluorinated compounds (PFCs), all Fluorinert variants have an extremely high global warming potential (GWP), [1] so should be used with caution (see below).
