Not sure what that sodium sulfate is about but all you need is an alcohol (methanol, ethanol or isopropyl will do) and HCl or sulfuric acid. Plus distilled water and maybe some hydrogen peroxide to clean the sulfuric acid. (You don’t HAVE to clean the acid but if your anal about impurities you can.). Sulfuric acid is what I used back in the day, found as drain cleaner at hardware stores.
Also this can be done on crude extracts and even plant material. Your gonna use more reagents than if you had just done an extract, for the plant material, but when looking at the cost of drain cleaner and alcohol not a huge loss.
(Fill your flask with plant material, pour in alcohol until you’ve just covered the plant material, keep track of the volume of alcohol then just drip in 1 drop sulfuric acid per 15ml alcohol. Reflux until satisfied, then filter off alcohol. Flood alcohol with equal amount of water. Watch as the dark oils separate from the milky white/green solution. This can be manually separated. Otherwise add toluene and shake together contents, carefully to avoid emulsions. Separate toluene and evaporate in a glass tray to yield oil. Redissolve in minimal alcohol and re-evaporate to ensure no toluene is left trapped in the oil.)
