Hi all, Again I have had some troubles with my health, so I haven't been around for a while. But as we say in Holland "Weeds aren't killed". I have done as written below and do not understand a thing of it. Who can help ?
I took 800 liters of used oil, which is used for a day or two to bake fish in at 180¡ C. I titratet 4 ml so that brings me to 7.5 grams of NaOH per liter = 6 kg NaOH The NaOH was dissolved completely in 96 kg methanol ( 120 liters ). This was mixed using a strong pump with the oil during 1 hour, ( which I boiled first to 120¡ C to make sure there whas no trace of water in the oil. I filtered the hot oil and let it cool down to about 30¡ C). I think I have made BD now. I usually make BD with different amounts of NaOH, because I used to get the oil from somebody else. Anyway, separation occured and the s.g. of the BD is 0,860 which is not too bad, I would think. Now I took 525 grams of the bottom layer ( I did not perform the whashing process at all, so there cannot be any water ). Then I mixed this with 34 ml phosphoric acid (75%). After a short time separation occured : A light sherry / goldish toplayer , a bit darker than sunflower oil, which is, I guess 80% of the total lot. A complete black middle layer, which is maybe 5% of the lot A bottomlayer which has the color off coffee with milk, which is about 10% of the lot. This is not the result I expected. I realize I have asked this before and at that time I did not manage to seperate FFA and glycerin ( maybe I did, but not knowing what the glycerin or the FFA whas ). So, what did I produce and what can I do whith it ?
