What We Carry
Our petroleum collection includes methanol/water solutions (60/40 ratios), ethylene glycol formulations (50/50 and 60/40 concentrations), and high-purity hydrocarbon solvents. Available grades range from technical grade for industrial applications to ACS reagent grade for analytical work. Most products are liquid solutions, with some available as neat chemicals for custom blending.
Available Pack Sizes
We stock petroleum chemicals in quart bottles through 275-gallon totes, including 1-gallon jugs, 5-gallon pails, and 55-gallon drums. This range accommodates everything from laboratory testing to large-scale industrial operations.
All petroleum chemicals meet relevant ASTM specifications and industry standards. Understanding chemical grades helps ensure you select the right purity level for your specific application requirements.
Every order includes complete SDS and COA documentation for regulatory compliance and quality assurance. We offer same-day shipping with no minimum order requirements, supporting both emergency needs and routine procurement schedules.

Frequently Asked Questions
What chemicals are commonly used in petroleum refining?
Petroleum refineries use a variety of chemicals throughout their processes. Common examples include solvents like toluene and MEK for extraction and cleaning, acids such as sulfuric and hydrochloric acid for various reactions and pH adjustments, and demulsifiers to separate crude oil. Alliance Chemical offers many of these chemicals in bulk and smaller quantities.
How are chemicals used in drilling fluids?
Drilling fluids, or muds, require a range of chemicals to control viscosity, density, and pH. Barite is commonly used to increase density, while polymers like xanthan gum act as viscosifiers. Chemicals like calcium chloride or potassium chloride can also be added to inhibit clay swelling. Alliance Chemical provides many of these products for optimal drilling fluid performance.
What is crude oil demulsification and what chemicals are used?
Crude oil demulsification is the process of separating water from crude oil emulsions. This is typically done using chemical demulsifiers, which are surfactants that destabilize the emulsion, allowing the water to separate. Alliance Chemical supplies various demulsifying agents for the oil and gas industry.
Which chemicals are used for pipeline corrosion inhibition?
Pipeline corrosion is a major concern in the petroleum industry. To prevent corrosion, corrosion inhibitors are added to the pipeline, which form a protective film on the metal surface, preventing it from reacting with corrosive substances. Common corrosion inhibitors include amines and phosphate esters, many of which are available from Alliance Chemical.
What are some common chemicals used for petroleum lab testing?
Petroleum laboratory testing relies on high-purity chemicals for accurate analysis. Solvents such as hexane, toluene, and methanol are frequently used for sample preparation and analysis using methods such as ASTM. Alliance Chemical provides ACS-grade solvents and reagents for reliable laboratory results. We also supply pre-mixed solutions like 60/40 Methanol/DI Water.
What is 60/40 Methanol/DI Water solution used for?
A 60/40 Methanol/DI Water solution is frequently used in laboratory settings, particularly for aflatoxin testing in peanuts. The methanol acts as a solvent to extract the aflatoxins, while the deionized water helps to optimize the extraction process. Alliance Chemical provides this solution in both standard and ACS grades.
How should I safely store chemicals used in the petroleum industry?
Safe chemical storage is critical. Always consult the SDS for specific instructions for each chemical. General guidelines include storing chemicals in tightly sealed, properly labeled containers in a cool, dry, and well-ventilated area away from incompatible materials. Alliance Chemical provides SDS documents for all our chemicals.
What safety precautions should I take when handling chemicals used in petroleum refining?
Always wear appropriate personal protective equipment (PPE), such as gloves, eye protection, and respiratory protection, when handling chemicals. Work in a well-ventilated area to avoid inhaling vapors. Refer to the SDS for detailed safety information, including first aid measures in case of exposure. Alliance Chemical prioritizes safety and provides comprehensive safety information with all products.
What are some common applications of Methanol in the petroleum industry?
Methanol has a multitude of uses in the petroleum industry. It can act as a solvent in laboratory testing, used to create solutions that test for the presence of aflatoxins. It can also be a cost-effective and energy-efficient fuel source, especially when compared to gasoline.
What are the ACS grade specifications and why is it important?
ACS grade chemicals meet the purity standards set by the American Chemical Society. This level of purity is essential for reliable and reproducible results in laboratory analysis and research, as it minimizes the interference of impurities. Alliance Chemical offers many chemicals in ACS grade to meet stringent requirements.
