About Hemp

Alliance Chemical provides high-purity solvents and specialty chemicals specifically selected for hemp and cannabis extraction, purification, and analytical testing operations. Our products meet the stringent purity requirements demanded by state regulations and laboratory accreditation standards, supporting both commercial-scale extraction facilities and analytical testing laboratories.

Common Applications

  • Ethanol extraction: Primary solvent for cannabinoid and terpene extraction from hemp biomass
  • Hydrocarbon extraction: Butane and propane-based extraction systems for concentrates
  • Winterization processes: Low-temperature ethanol treatment to remove fats, waxes, and lipids
  • Analytical testing: Mobile phase solvents for HPLC potency testing and terpene analysis
  • Residual solvent testing: Reference standards and carrier solvents for GC/MS analysis
  • Post-extraction refinement: Distillation and purification of crude extracts

What We Carry

Our hemp extraction collection features ACS reagent grade and food-grade solvents including ethanol, isopropyl alcohol, hexane, n-heptane, and ethyl acetate. We also supply specialty chemicals like d-limonene (94% food grade) for terpene applications and polyethylene glycol (PEG) for formulation work. All solvents meet or exceed industry purity standards with typical concentrations ranging from 94% to 99.9%.

Available Pack Sizes

Products are available in laboratory quantities from 1-quart bottles up to production volumes including 5-gallon pails, 55-gallon drums, and 275-gallon totes. This flexibility supports everything from R&D testing to commercial extraction operations.

Understanding solvent specifications is critical for hemp applications. Review our full chemical grades guide to select the appropriate grade for your specific process requirements.

Every order includes complete Safety Data Sheets (SDS) and Certificates of Analysis (COA) to support regulatory compliance and quality assurance protocols. We offer 1-2 business day shipping on in-stock items with no minimum order requirements, ensuring you maintain continuous operations.

Frequently Asked Questions

What types of solvents are most effective for hemp and cannabis extraction?
Ethanol and hydrocarbon solvents are commonly used in the extraction of cannabinoids. They provide high efficiency in extracting desired compounds while maintaining product purity. Alliance Chemical offers a variety of high-purity solvents suited for different extraction processes.
How do I choose the right grade of ethanol for cannabis extraction?
When selecting ethanol for cannabis extraction, it’s important to consider purity levels. Food-grade or pharmaceutical-grade ethanol is often required to ensure safety and effectiveness. Alliance Chemical provides ethanol in various grades tailored to the needs of extraction processes.
How is winterization important in the purification process of cannabinoids?
Winterization is crucial for removing fats, waxes, and lipids from cannabis extracts, which ensures a cleaner final product. This process typically requires solvents that effectively separate these impurities at low temperatures. Alliance Chemical supplies solvents that facilitate efficient winterization.
Is it safe to handle solvents used in cannabis extraction?
Handling solvents requires adherence to safety protocols, as many are flammable or toxic. It is essential to store these chemicals in a well-ventilated area, away from ignition sources. Alliance Chemical provides detailed safety data sheets for each product, promoting safe usage and storage.
What storage conditions are recommended for solvents used in extraction processes?
Solvents should be stored in a cool, dry place, away from direct sunlight and heat sources. Proper labeling and secure containers are essential to prevent leaks or spills. Alliance Chemical offers guidance on safe storage practices to maintain solvent integrity.
Which solvents are best for potency and terpene testing?
Solvents like ethanol and methanol are frequently used for cannabis potency and terpene analysis due to their ability to dissolve a wide range of chemical compounds. Alliance Chemical supplies these solvents in analytical grades to ensure precise testing results.
How do I safely dispose of residual solvents from extraction processes?
Residual solvents should be disposed of according to local regulations, typically through hazardous waste management services. It is important not to pour solvents down the drain. Alliance Chemical can provide guidance on proper disposal methods compliant with industry standards.
What role do solvents play in post-extraction refinement and distillation?
Solvents are crucial in separating and purifying extracted compounds during refinement and distillation. They assist in removing residuals and achieving the desired concentration of cannabinoids. Alliance Chemical offers a range of solvents specialized for refinement and distillation purposes.
