In aqueous solutions, hydrogen peroxide forms a eutectic mixture, exhibiting freezing-point depression down as low as -56 °C; pure water has a freezing point of 0 °C and pure hydrogen peroxide of -0.43 °C. The boiling point of the same mixtures is also depressed in relation with the mean of both boiling points (125.1 °C). It occurs at 114 °C.
Fm. Md. No. Legend. Values are in kelvin K and degrees Celsius °C, rounded. For the equivalent in degrees Fahrenheit °F, see: Boiling points of the elements (data page) Some values are predictions. Primordial From decay Synthetic Border shows natural occurrence of the element. s-block.
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.
High-test peroxide (HTP) is a highly concentrated (85 to 98%) solution of hydrogen peroxide, with the remainder consisting predominantly of water. In contact with a catalyst, it decomposes into a high-temperature mixture of steam and oxygen, with no remaining liquid water. It was used as a propellant of HTP rockets and torpedoes, and has been ...
Piranha solution, also known as piranha etch, is a mixture of sulfuric acid (H2SO4) and hydrogen peroxide (H2O2). The resulting mixture is used to clean organic residues off substrates, for example silicon wafers. [ 1 ] Because the mixture is a strong oxidizing agent, it will decompose most organic matter, and it will also hydroxylate most ...
The general structure of an organic peroxide. In organic chemistry, organic peroxidesare organic compoundscontaining the peroxidefunctional group(R−O−O−R′). If the R′ is hydrogen, the compounds are called hydroperoxides, which are discussed in that article. The O−O bond of peroxides easily breaks, producing free radicalsof the form ...
Hydrogen peroxide–urea is a readily water-soluble, odorless, crystalline solid, which is available as white powder or colorless needles or platelets. [ 2 ] Upon dissolving in various solvents, the 1:1 complex dissociates back to urea and hydrogen peroxide. So just like hydrogen peroxide, the (erroneously) so-called adduct is an oxidizer but ...
Hydrogen peroxide is the oxidant in the hydrogen peroxide to propylene oxide (HPPO) process, catalyzed by a titanium-doped silicalite: C 3 H 6 + H 2 O 2 → C 3 H 6 O + H 2 O; In principle, this process produces only water as a side product. In practice, some ring-opened derivatives of PO are generated. [12]
