Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for extracting CBD from hemp oil do not effectively achieve high CBD content while minimizing THC levels, which is crucial for maximizing the therapeutic potential of hemp oil.
Innovation Solution
A process involving decarboxylation of CBDA, short-path evaporation to isolate CBD, and selective THC to CBN conversion, followed by winterization and flash chromatography purification to enhance CBD purity and reduce THC content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional extraction methods are used, then the process is simple, but the CBD content is low and THC content is high
Solution Approach 1:
The extraction process is divided into multiple distinct stages: (1) decarboxylation to convert CBDA to CBD, (2) short-path evaporation to concentrate and purify CBD, (3) selective THC to CBN conversion to reduce THC content, and (4) winterization and flash chromatography for final purification. Each stage targets specific purification objectives, enabling high CBD content (up to 60%) while minimizing THC levels (less than 1%) through systematic separation and conversion steps.
2Quantity of substance
If conventional extraction methods are used, then the process is straightforward, but THC levels remain high reducing therapeutic potential
Solution Approach 1:
The process converts harmful THC into beneficial CBN through selective thermal degradation at controlled temperatures (80-100°C) for extended periods. This transformation not only reduces THC content to less than 1% but also produces CBN, which has its own therapeutic properties, thereby converting a harmful substance into a beneficial one while achieving the primary goal of high CBD content (up to 60%).
Solution Approach 2:
The process employs precise control of temperature parameters at different stages: decarboxylation at 150-160°C for 10-18 hours to convert CBDA to CBD, followed by THC to CBN conversion at 80-100°C for several days to weeks. These controlled parameter changes enable selective chemical transformations that maximize CBD content while minimizing residual THC levels.
3Manufacturing precision
If multiple purification steps are added, then CBD purity increases, but processing time increases
Solution Approach 1:
The process performs preliminary decarboxylation of CBDA to CBD before the main purification steps, and conducts preliminary THC to CBN conversion during the same thermal processing stage. By completing these preparatory transformations early in the process, subsequent purification steps (winterization and flash chromatography) operate on already-transformed material, reducing the overall time required to achieve high CBD purity (up to 60%) and low THC content (less than 1%).
