The FOX reagent, or ferrous oxidation−xylenol orange, is used to measure levels of hydrogen peroxide in biological systems. [1] The reagent is incubated with the sample and absorbance of the product form after a series of oxidation reactions is then measured at a wavelength of 560 nm.
The package containing the peroxide is placed in oven set for test temperature; The timer starts when product reaches 2 °C below intended test temperature; The oven is held at constant temperature for up to one week or, until a runaway event occurs. Test "Passes" if product does not exceed test (oven) temperature by 6 °C within one week
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.
MAP Test (stylized MaP Test, an acronym for Maximum Performance Test), is an independent, third-party testing regimen for the flushing power of contemporary toilets. It uses a combination of toilet paper and soybean paste .
Dialkyl peroxides, e.g., dicumyl peroxide, are synthesized by addition of hydrogen peroxide to alkenes or by O-alkylation of hydroperoxides. Diacyl peroxides are typically prepared by treating hydrogen peroxide with acid chlorides or acid anhydrides in the presence of base: [1] H 2 O 2 + 2 RCOCl → (RCO 2) 2 + 2 HCl H 2 O 2 + (RCO) 2 O → ...
Elephant toothpaste reaction Two people watching the reaction of Elephant's toothpaste. Elephant's toothpaste is a foamy substance caused by the quick decomposition of hydrogen peroxide (H 2 O 2) using potassium iodide (KI) or yeast and warm water as a catalyst. [1]
In chemistry, main group peroxides are peroxide derivatives of the main group elements. Many compounds of the main group elements form peroxides ( R−O−O−R' ), and a few are of commercial significance.
The primary stereoelectronic effect in the Baeyer–Villiger oxidation refers to the necessity of the oxygen-oxygen bond in the peroxide group to be antiperiplanar to the group that migrates. [4] [3] This orientation facilitates optimum overlap of the 𝛔 orbital of the migrating group to the 𝛔* orbital of the peroxide group. [1]
