Butane (C₄H₁₀) Gas | Industrial, High Purity & LPG Grade Supplier

Butane (C₄H₁₀) Gas | Industrial, High Purity & LPG Grade Supplier

Supplier: Wenzhou Yingyue New Materials Co., Ltd.

Product Overview

Butane (C₄H₁₀) is a colorless, odorless, highly flammable alkane hydrocarbon gas, existing in two isomeric forms: n-butane and isobutane. It is a major component of liquefied petroleum gas (LPG) and easily liquefies under moderate pressure at room temperature. Yingyue New Materials provides full-series butane products ranging from industrial fuel grade to 99.999% ultra-high purity, available in both compressed gas and liquefied forms. Adopting advanced distillation and isomer separation technology, our C₄H₁₀ features precise isomer ratio control and ultra-low impurity content. All batches are equipped with standard COA and MSDS, supporting customized packaging and global export services.

Key Product Specifications

Purity Grade & Impurity Control

We supply full-gradient butane gas strictly complying with GB/T 19465-2004 national standard, with precise isomer separation and batch-by-batch impurity testing to meet industrial fuel, chemical synthesis and special application scenarios:

1. Industrial Fuel Grade (≥95.0%)

Suitable for industrial heating, boiler fuel, metal cutting and general LPG applications. Strictly control common impurities such as ethane, propane, pentane, water and sulfur compounds, with stable combustion performance and high calorific value, meeting the basic energy supply needs of industrial production.

2. High Purity Grade (99.5%-99.9%)

Applied for chemical synthesis, aerosol propellants and conventional laboratory experiments. Controlled impurities: Total unsaturated hydrocarbons ≤50ppm, Moisture ≤10ppm, Sulfur ≤1ppm, with precise n-butane/isobutane ratio control according to customer requirements.

3. Ultra-High Purity Grade (99.99%-99.999%)

Dedicated for electronic industry, semiconductor manufacturing, refrigerant production and precision instrument calibration. After deep purification and molecular sieve adsorption treatment, trace impurities such as moisture, heavy hydrocarbons and heteroatomic compounds are controlled below 0.1ppm. It features ultra-high purity and stable chemical properties, fully adapting to high-precision industrial and scientific research scenarios.

Physical & Chemical Properties

Butane (C₄H₁₀) is the fourth member of the alkane series with stable chemical properties under normal temperature and pressure. It is colorless, odorless, significantly heavier than air, and slightly soluble in water, easily soluble in organic solvents such as ethanol and ether.

Butane has excellent combustion performance with high calorific value (49.5 MJ/kg) and clean combustion products. It is chemically inert at room temperature and does not react with common strong acids, strong alkalis and oxidants. Under high temperature, high pressure or catalytic conditions, it can undergo oxidation, substitution, isomerization and pyrolysis reactions, which is an important raw material for organic chemical synthesis. It has a flammable explosion limit of 1.9%~8.5% in air, requiring standardized storage and transportation.

• Industrial Liquefied Butane Cylinders: 50KG YSP-50 standard liquefied butane cylinders, with special two-phase valves (liquid phase + gas phase) for industrial use. All cylinders are inspected and certified by national authorities, with insurance coverage. Suitable for large-scale industrial heating, metal processing and chemical production.

• Cylinder Bundle Packaging: 6-pack and 12-pack cylinder bundles are provided for centralized storage and transportation, which is convenient for factory continuous gas supply and large-scale industrial supporting use.

• Bulk Transportation: Equipped with dedicated flammable gas tank trucks and ISO standard tank containers for bulk delivery, realizing stable and low-cost gas supply for large industrial parks.

• Customized Service: Support personalized customization of filling pressure, gas purity, n-butane/isobutane ratio and valve interface models to match different customer equipment and production needs.

Main Applications

Butane gas is widely used in energy supply, chemical industry, daily chemical and refrigeration fields, with unique advantages in low-pressure liquefaction applications:

1. Industrial Energy Fuel: Used as clean burning fuel for industrial boilers, heating equipment, metal cutting and welding processes, with high calorific value and low pollution emissions.

2. Aerosol Propellant: The most widely used propellant in aerosol products such as spray paints, insecticides, personal care products and air fresheners, due to its excellent low-pressure liquefaction properties.

3. Refrigeration Industry: Used as a natural refrigerant (R600a) in household refrigerators and freezers, with zero ozone depletion potential and low global warming potential.

4. Chemical Raw Material: Applied for the synthesis of butadiene, maleic anhydride, acetic acid and other chemical products, serving the petrochemical and fine chemical industries.

5. Foaming Agent: Used as a foaming agent in the production of polystyrene foam and polyurethane foam, providing excellent insulation performance.

6. Laboratory & Detection Industry: Used as standard calibration gas for gas chromatography, environmental monitoring and industrial instrument verification.

Safety & Export Compliance

All butane gas products comply with UN1011 flammable gas transportation standards and relevant national specifications. Butane is a flammable and explosive gas, which is significantly heavier than air and may accumulate in low-lying areas. For liquefied butane cylinders, they must be stored and used in an upright position to prevent liquid leakage. Keep away from open fire and high-temperature heat sources. We provide complete export documents including MSDS safety data sheet, batch COA quality certificate and origin certification, and provide professional safety operation guidance to ensure safe use and smooth global customs clearance.
