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.

Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:
Note that the form of this formula as given is a fit to the Clausius–Clapeyron equation, which is a good theoretical starting point for calculating saturation vapor pressures: log 10 (P) = −(0.05223) a / T + b , where P is in mmHg, T is in kelvins, a = 38324, and b = 8.8017.
A series of studies have shown that bromophenols derived from brominated flame retardants (BFRs) in human environments are present in human blood and breast milk. [1] Bromophenols (as well as PBDEs ) were detected in 88% of samples, with 2,4,6-Tribromophenol present in 84% of breast milk samples alone.
As such, its systematic IUPAC name is 1-phenyl-2-propanone. This substance is used in the manufacture of methamphetamine and amphetamine , where it is commonly known as P2P . [ 2 ] [ 3 ] Due to illicit drug labs using phenylacetone to make amphetamines, phenylacetone was declared a schedule II controlled substance in the United States in 1980 ...
Phenanthrene is a polycyclic aromatic hydrocarbon (PAH) with formula C 14 H 10, consisting of three fused benzene rings. It is a colorless, crystal-like solid, but can also appear yellow.
Phenacyl chloride, also commonly known as chloroacetophenone, is a substituted acetophenone.It is a useful building block in organic chemistry.Apart from that, it has been historically used as a riot control agent, where it is designated CN. [5]
