So, pour into flask you're safrole oil, in other flask mix NaOH(i'm actually have no clue how much of oil do you, to know how much to add of cautistic soda, you need to know how much militers do you have of oil and divide on 2, keyword math). After you poured NaOH add the water(now you need increase cautistic soda amount on 2). Now you poured water, mix until dissolves, add in oil you're alkaline mixture, mix, and you need heat you're oil with mixture on 65*C of degrees, after you see topper layer was appearing, stop the heating, now wait until mixture will cool to room temperature, after it cooled, you can seperate the topper layer, using the syringe add to beaker, wait 4-7 hours for crystalize, after crystalization, add 50ml of isopropyl alcohol, heat about same 65*C degrees, after crystals dissolved, you can stop stirring and heatting, wait until it will cool to room temperature, in 6 or 7 hours crystals will appear, check the pH if it's not 5, make the pH mixture, add 50ml of acetone and and 2ml of hydrocloric acid, now you can add with syringe you're pH mixture and in same time mix, after you're pH is 5, you can filtrate, and let mda dry.
