Hi Andres >Thanks for your email....well i used 900 ml of Soy oil, 180 ml of Methanol, >3.15g of NaOH..Temperatura was since 132.8 ºF to 122 ºF and 60 minutes of >proccesing. I obtained: > * 80 ml of glicerin layer > * 1000 ml of methyl ester layer >Then the 1000ml of methyl ester layer was washed by stir washing with 334 ml >of water to 95 ºF, with this it formed 0.276 inches of soap layer between BD >and water. This is my first test batch
Fox was right: > try KOH rather than NaOH. Go to the beginning, that's here: Where do I start? http://journeytoforever.org/biodiesel_make.html#start And go down to "Make your first test batch": > Either potassium hydroxide (KOH) or sodium hydroxide (NaOH) can be >used, but we recommend KOH, especially for beginners -- KOH is >easier to use and it gives better results It's a 10-step process. Step 6 is settling after processing: >...

But you seem to have missed Step 7 and gone straight on to Step 8, Washing. Step 7 ends with this: > Here's what to do if your test batch fails the tests. > <http://journeytoforever.org/biodiesel_vehicle.html#whatdo> That's this: >What should you do if your fuel doesn't pass the wash-test? >The three main reasons test batches fail are failure to follow the >instructions properly, inaccurate measurements, and poor-quality >chemicals, in that order... Also: How to use the quality tests: <http://journeytoforever.org/biodiesel_vehicle.html#howtotsts> The Wash test section says: > The biodiesel should separate from the water in half an hour or >less, with amber (and cloudy) biodiesel on top and milky water >below, and no more than a "paper-thin" white layer between the oil >and water. So your test batch probably wouldn't have passed the test, but it's a good sign that it survived stir-washing without emulsifying, you're doing well! Why not go back to the beginning and start again? Step by step, include the quality tests this time.
