Focus:

Tonight we made three batches of Ethyl Esters (Biodiesel).

Batch 1:

200 Proof Ethanol, New soybean oil.

Success!

Batch 2:

180 Proof Ethanol, New soybean oil.

No Success. Will put in sun to heat up and see if it recovers.

No recovery!

Batch 3:

200 Proof Ethanol, used fryer oil.

Success!

Ingredients:

Each batch was:

150 ml of ethanol

500 ml of oil

3.5 grams of NaOH (5 grams on the used fryer oil, based on titration results)

Technique's:

Mix the lye into the ethanol, and shake until the lye totally dissolves (about 10 minutes). This reaction creates heat, and we developed a leak in the plastic veggie bottle (due to the heat or the ethanol), so we switched to a glass bottle. Go Bacardi!

Then add the oil, and gently end-over-end the bottle, do not shake (5 to 10 times). Mixture will turn black, then silver then back to amber as it mixes. From new oil, the resulting biodiesel looks almost crystal clear. This is the "Soon to be famous Bacardi Technique (no Patent Pending)".
