Description

Petroleum Ether CAS NO 64742-82-1 is a highly volatile, low-boiling hydrocarbon fraction derived from petroleum refining, primarily consisting of aliphatic hydrocarbons like pentanes and hexanes. Its excellent solvency power and rapid evaporation rate make it an indispensable processing aid and extraction medium across numerous industries. This solvent is critical for manufacturers and laboratories requiring a reliable, non-polar medium for extraction, cleaning, and synthesis. Key sectors that depend on its consistent performance include pharmaceuticals, agrochemicals, polymer processing, and analytical chemistry.

Application

• Solvent Extraction: Widely used for the extraction of oils, fats, waxes, and natural products from biological materials in food and pharmaceutical manufacturing.
• Laboratory Reagent: Serves as a common non-polar solvent for chromatography, recrystallization, and general laboratory cleaning procedures.
• Polymer & Rubber Processing: Acts as a solvent and thinner in the production and processing of adhesives, rubber cements, and certain polymers.
• Industrial Cleaning: Employed as a degreasing agent and cleaning solvent for machinery, metal parts, and precision instruments due to its ability to dissolve oils without residue.
• Chemical Synthesis: Utilized as a reaction medium and solvent in organic synthesis and the production of agrochemicals and specialty chemicals.
• Fuel & Energy: Certain grades can be used as a component in specialty fuels, camping stove fuel, or as a solvent in petroleum product formulation.

Quality Control

Our Petroleum Ether is produced under strict quality management protocols to ensure batch-to-batch consistency and reliability. Quality is verified through comprehensive testing including distillation range, residue on evaporation, acidity/alkalinity, and water content. A Certificate of Analysis (COA) detailing all test results is provided with each shipment. We adhere to relevant industry standards and our quality systems are designed to support applications requiring high-purity, low-residue solvents.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile nature, keep containers tightly sealed when not in use to prevent evaporation and maintain purity. Store away from strong oxidizing agents. Recommended storage temperature is 15-25°C.
