Re: First time making bio diesel

I don't know anything about "heat" but if there is any water in the product, it is really going to mess with your process.

Otherwise, what you are doing sounds more or less fine.  The "foam" that you are talking about is probably an emulsion layer, which is no big deal, except it means that you have water in your process somewhere (and my guess is from the "Heat.")  That will settle back into water (which will end up in the glycerin layer) and biodiesel.  An emulsion layer regularly happens during water washes when one mixes vigorously.

Subject: [pdx-biodiesel] First time making bio diesel

I am a first time maker of bio diesel, and I would appriciate some feed back on my test results.
I am using a product called Heat for the methanol. on a previous test suing 200ml of methanol (Heat) my gliceran was only 125 ml, so I increased the methanol to 325 ml. I am thinking that the Heat is not pure methanol, so I compinsated by increasing to have an equivelant of 200ml.
I am using KOH, and according to the instructions in "Make your own biodiesel", I uncreased the KOH to 5g.
I used new vegatable oil and heated 1 litre to 130 deg F.
I then poured the oil into a blinder, and retested the temp, and it was 130 deg F
I poured in the methanol/KOH mix and mised it for 5o minutes.
I then let it set for 24 hours.
In the wash test I had a good seperation of the water withen 30 minuits, but I have a small white fome that seperates the water from the oil.
Is this bad, and if so do you have any idea of what I did wrong.
One more thing. I am doing this in my shop in Idaho, and the temp outside was 30 deg F, so I put my shop lamp about 2 feet from the mixer to compinsate for the cold.

Thanks, John
