CO2 Extraction Process for THC: A Supercritical Approach

Introduction

Tetrahydrocannabinol (THC) is the primary psychoactive compound in cannabis, responsible for its euphoric and medicinal effects. Extracting THC efficiently and without chemical solvents is essential for medical, recreational, and pharmaceutical applications.

Traditional extraction methods, such as ethanol or hydrocarbon (butane, propane) extraction, often lead to residual solvents, loss of terpenes, and inconsistent cannabinoid profiles.

CO2 supercritical extraction (CO2 SUPERCRITICAL EXTRACTION MACHINE) is a solvent-free, highly selective, and high-purity method for extracting THC, ensuring optimal cannabinoid retention, enhanced terpene preservation, and eco-friendly processing.

This article explores the CO2 extraction process for THC, key parameters, experimental data, and industrial applications.

1. Principles of CO2 Supercritical Extraction for THC

CO2 reaches its supercritical state at 31.1°C and 7.38 MPa, allowing it to behave both as a gas and a liquid. This enables CO2 to penetrate cannabis material and selectively dissolve THC, terpenes, and other cannabinoids while leaving behind undesirable compounds like waxes and chlorophyll.

The CO2 supercritical THC extraction process consists of:...
