Hydrogen Peroxide CAS 7722-84-1

Hydrogen Peroxide is a versatile inorganic compound widely used in various industrial fields. As an important chemical raw material, it is highly sought after by global import purchasers for its excellent oxidizing properties and environmental friendliness. This page provides detailed information about hydrogen peroxide, including its aliases, physical properties, product specifications, applications, and related services to help purchasers make informed purchasing decisions.

Product Aliases

Hydrogen peroxide has multiple common aliases in the industry, including Hydrogen Dioxide, Dihydrogen Dioxide, Peroxide, Perhydrol, Perdrogen, and Superoxol. Its aqueous solution is commonly known as Hydrogen Peroxide Solution or H2O2 Solution in daily and industrial scenarios.

Product Properties & Physical Characteristics

The molecular formula of hydrogen peroxide is H2O2, with a molecular weight of 34.01. Its CAS number is 7722-84-1, which is the unique identifier for global chemical registration and trade.

Pure hydrogen peroxide is a pale blue viscous liquid, while its aqueous solution (the most commonly used form in industry) is a colorless transparent liquid with a faint special odor. It is slightly soluble in alcohol and ether, insoluble in petroleum ether and benzene, and can be mixed with water in any proportion.

Key physical properties are as follows: melting point (anhydrous) is -2℃, boiling point (anhydrous) is 158℃, relative density (water = 1, anhydrous) is 1.46, and saturated vapor pressure is 0.13 kPa (15.3℃). It is a stable compound under normal storage conditions, but it decomposes easily under strong light, high temperature, or contact with heavy metals and their oxides.

Common Product Specifications

The most commonly used grade of hydrogen peroxide in industrial applications is the 27.5% concentration grade, which balances cost-effectiveness and application performance. The detailed specifications are shown in the following table:

Product Applications

Hydrogen Peroxide is known as a "versatile chemical" due to its wide range of applications across multiple industries. As a green oxidant, its decomposition products are only water and oxygen, making it environmentally friendly and widely used in green chemical processes.

1. Textile Industry: Used for bleaching various textiles and knitted fabrics, replacing traditional chlorine bleaching to reduce fiber damage and environmental pollution, and improve fabric whiteness and hand feel.

2. Papermaking Industry: An important bleaching agent for pulp bleaching, which can improve paper whiteness and quality. It is widely promoted globally due to its environmental friendliness, replacing chlorine bleaching in many countries.

3. Chemical Synthesis: Used as a key oxidant in the synthesis of caprolactam (a raw material for nylon 6), percarbonate, perborate, and other chemicals, playing an important role in the organic synthesis industry.

4. Environmental Protection: Used for wastewater and waste gas treatment, effectively degrading harmful substances and improving environmental quality.

5. Electronics Industry: High-purity hydrogen peroxide is used as a cleaning and etching agent for silicon wafers and integrated circuits, which is crucial for the production of electronic products.

6. Other Fields: Also used in food disinfection, medical disinfection, cosmetics, and aerospace fields, with broad market demand.

Product Certification & Services

The product has completed REACH registration, complying with EU chemical regulations and ensuring smooth customs clearance and use in the European market. For the safety of use and transportation, MSDS download service is provided, which contains detailed safety information, emergency handling methods, and storage requirements to help purchasers use and manage the product safely.

FAQ

Q1: What is the shelf life of hydrogen peroxide under proper storage conditions?

A1: When stored in a cool, ventilated, and dark environment (temperature not exceeding 30℃) and away from flammables, reducing agents, and heavy metals, the shelf life of 27.5% concentration hydrogen peroxide is 6 months. Adding appropriate stabilizers can extend the shelf life appropriately.

Q2: Is hydrogen peroxide classified as a dangerous goods, and what precautions should be taken during transportation?

A2: Hydrogen peroxide is classified as a dangerous good (UN number: 2015, hazard class: 5.1 oxidizing agent). During transportation, it should be packed in corrosion-resistant containers, avoided from sunlight and high temperature, and not mixed with flammables, reducing agents, or metal powders. It should be handled with care to prevent container damage.

Q3: Can customized concentration grades of hydrogen peroxide be provided according to purchasing needs?

A3: Yes, in addition to the commonly used 27.5% grade, customized concentration grades (such as 35%, 50%) can be provided according to specific application needs of purchasers, with stable product quality and consistent compliance with international standards.
