One I had 15 g of chopped up ginger and 7.5 g of cinnamon for 300 ml of 70% ethanol. It depends on how strong you want to make it tho. I place x amount of one spice with y amount of another spice. I have also tried ethanol with Pepper (black) and Paprika and Dill aroma. Nutmeg (96% ethanol (Salting out required). Calcium carbonate boiling chips do not work due to the acid (Sulfuric) and dissolve and create a big mess and ruins your results.įor many of the samples, I pour in 250-450 ml of 70 percent ethanol with a vary of grams of chemicals.ġ. Even if 500 grams cost 50 dollars it is well Worth it in the long run.Įventually, I will show how to make with concentrated Sulfuric acid, Alcohol (near 95 percent) and organic acid some simple esters. Heating even a boiling flask halfway with ethanol (due to it volatile properties it must have proper boiling chips).I prefer expensive glass types. I strongly recommend (You MUST) have some type of glass or other boiling chips when working with ethanol. Boiling Sulfuric acid concentrate is a HUGE DIFFERENCE than the normal 20 degrees C!!!ĭistilling to 337 with a controlled heating mantle in a well-ventilated area is a bit better and may give a better purity (95-98) percent sulfuric acid. The lower the temperature the less energy it will release. The Hydrogen peroxide concentrated should be in the fridge or ice cold. Indeed this can work but the H202 has be added to the Sulfuric acid (Not the OTHER WAY AROUND) if it is done incorrectly it could explode!!! It forms Caro's Acid (Weak version) that attacks the Corrosion inhibitors. It produces some Sulfuric acid vapors which are class 1 cancer-causing and very corrosive and toxic by inhalation, skin contact. Glass boiling chips in a large amount equal mass of the volume (Must be ADDED). Then boil it.īoth Distilling Sulfuric acid and boiling it to 327 degrees C with Hydrogen peroxide (H202) is extremely dangerous. If you can get hold of Normally 96 percent Sulfuric acid Drain Cleaner with Inhibitor and you have the time and patience then you can add to 250 ml of Drain cleaner Acid about 15-20 ml very very Slowly 30-35 percent Hydrogen peroxide. I do not recommend doing this since it much much safer to buy Sulfuric acid 98 percent Online like E-bay, etc. I say if you get them cheaply just use 20 percent more. This means you can only get max 94-95 percent ethanol out of this way.Īnother video on Lab grade vs Chinese Molecular Sieves. Since they add 4-5 percent inhibitors ( to make it taste bad). Really strong aromas like Thyme may also need to be diluted.Īn alternative is to take 70 percent ethanol and use Molecular Sieves to remove water from the ethanol-making it near 94-95 percent ethanol. This concentrates the aroma in the ethanol.įor some aroma like Storax and Pine resin in 70 percent may be too strong alone and may have to be diluted with 70-95 percent ethanol ( Half of the Pine or Storax or One-fourth of it) or Lower. I place freshly chopped aromas in ethanol in the boiling flask as a reflux type material. I use my Soxhlet extractor for extracting aromas in ethanol. Here another Video from Troll face on salting out yes for many soluble alcohols (Methyl, Ethyl, and Isopropyl) as primary alc you can use this method for very pure alcohol. Here is a video on how to convert 70 percent ethanol into 95 percent min ethanol by salting out. Most ethanol you can buy 70 percent is pretty good however in some cases when you make ester (Ethyl acetate, Ethyl formate, etc) you require Ultra pure ethanol. For the reflux and the prep of the herbal soxhlet extraction always check on it 10-15 minutes and do not leave it on for long periods of time (Max 6 hours a day). For the esters, it should be done in a well-ventilated area. Making ester often requires concentrated organic acid which is corrosive and toxic. Acid burns, especially at this concentration, really hurt. Sulfuric acid 98% is an extremely powerful acid wear thick Nitrile gloves (Min) to protect yourself from skin contact. Distillation without an Oil bath can lead to cracks in the flask potentially causing an explosion. Warning: Ethanol and other alcohols are flammable and toxic (external uses only). I have made Cocoa aroma perfume in ethanol 70 percent, Ginger-Cinnamon in 70 percent ethanol, Methyl salicylate and Menthol from pain liquid gel in 70 percent ethanol and Storax resin in 70 percent ethanol. Hello, I really like making my own scent with spices, herbs, etc.
