Supercritical CO2 vs Solvent Extraction for Nicotine Extraction

Nicotine extraction is a critical process in the **tobacco and pharmaceutical industries**, where purity and safety are paramount. This article compares **supercritical CO2 extraction** and **solvent extraction** for nicotine, analyzing their advantages and limitations.

1. Purity and Chemical Integrity

• Supercritical CO2 Extraction: Produces **pure nicotine extracts**, free of **solvent residues**.
• Solvent Extraction: Uses **chemical solvents** that may require **additional purification** to eliminate residues.

2. Safety and Environmental Impact

• CO2 Extraction: **Non-toxic and environmentally friendly**, with no hazardous waste.
• Solvent Extraction: Uses **flammable solvents**, increasing risks of **chemical exposure** and **pollution**.

3. Efficiency and Yield

• CO2 Extraction: Selectively extracts **high-purity nicotine** with minimal degradation.
• Solvent Extraction: May extract **unwanted byproducts**, requiring additional refining steps.

4. Case Study: CO2 Extraction for Pharmaceutical Nicotine

A nicotine supplier transitioned from solvent extraction to CO2 extraction, improving **product consistency** and meeting **higher regulatory standards**.

5. Conclusion

For **high-purity nicotine extraction**, **supercritical CO2 extraction** is the optimal choice. Companies like **SHANGHAI NORTH BROOKS** offer **cutting-edge CO2 SUPERCRITICAL EXTRACTION MACHINE** solutions, ensuring **efficiency, purity, and safety**.
