Description
Peroxodisulfuric acid, also known as H4S2O8, is a strong acid that forms colorless crystals. When pure, it melts with decomposition at 65 °C. Peroxodisulfuric acid is not stable, and its solutions are reasonably stable when cool but hydrolyze rapidly to hydrogen peroxide and sulfuric acid when heated in strongly acidic solutions.
Uses
Used in Chemical Synthesis:
Peroxodisulfuric acid is used as an oxidizing agent for various chemical reactions, including the oxidation of alkenes to epoxides, the oxidation of alcohols to aldehydes or ketones, and the oxidation of sulfides to sulfoxides or sulfates. Its strong oxidizing properties make it a versatile compound in the synthesis of different organic and inorganic compounds.
Used in Analytical Chemistry:
In analytical chemistry, peroxodisulfuric acid is used as a titrant in redox titrations, such as the determination of iron(II) ions in the presence of iron(III) ions. Its strong oxidizing nature allows for accurate and precise measurements in various analytical applications.
Used in Environmental Applications:
Peroxodisulfuric acid can be employed in the treatment of wastewater and soil remediation due to its ability to oxidize various contaminants, such as organic pollutants and heavy metals. Its strong oxidizing properties help in breaking down harmful substances, making it a useful tool in environmental clean-up processes.
Used in Pharmaceutical Industry:
In the pharmaceutical industry, peroxodisulfuric acid may be used as a reagent in the synthesis of certain drugs and pharmaceutical compounds. Its oxidizing properties can be harnessed to facilitate specific chemical transformations, contributing to the production of various medications.
Used in Textile Industry:
Peroxodisulfuric acid can be utilized in the textile industry for processes such as bleaching and dyeing. Its strong oxidizing properties enable the removal of stains and impurities from fabrics, as well as the oxidation of certain dyes to achieve desired color effects.
Used in Cosmetics Industry:
In the cosmetics industry, peroxodisulfuric acid may be used as an ingredient in certain hair care and skin care products, where its oxidizing properties can contribute to the lightening or coloring of hair, or the removal of impurities from the skin. However, due to its strong oxidizing nature, it must be used with caution and in appropriate concentrations to ensure safety and effectiveness.
Check Digit Verification of cas no
The CAS Registry Mumber 13445-49-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,4 and 5 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13445-49:
(7*1)+(6*3)+(5*4)+(4*4)+(3*5)+(2*4)+(1*9)=93
93 % 10 = 3
So 13445-49-3 is a valid CAS Registry Number.

Anhydrous processing of methane into methane-sulfonic acid, methanol, and other compounds

Page/Page column 10-11, (2008/06/13)
Anhydrous processing to convert methane into oxygenates (such as methanol), liquid fuels, or olefins uses an initiator to create methyl radicals. These radicals combine with sulfur trioxide to form methyl-sulfonate radicals. These radicals attack fresh methane, forming stable methane-sulfonic acid (MSA) while creating new methyl radicals to sustain a chain reaction. This system avoids the use or creation of water, and liquid MSA is an amphoteric solvent that increasing the solubility and reactivity of methane and SO3. MSA from this process can be sold or used as a valuable chemical with no mercaptan or halogen impurities, or it can be heated and cracked to release methanol (a clean fuel, gasoline additive, and chemical feedstock) and sulfur dioxide (which can be oxidized to SO3 and recycled back into the reactor). MSA also can be converted into gasoline, olefins, or other valuable chemicals.
