Ok i did the Dr pepper ASTM reprocess test and the biodiesel that is washed and dried did not gel so added double the amount of methoxide and it formed a weak gel in about 4 minutes.
I used naoh in the methoxide but the biodiesel was made using koh.
I also did the other test that i take some of the biodiesel washed and dried and add some more methoxide that contains koh to the biodiesel shake it up and let it sit for 30 minutes and see if any more glycerine settles out or that the methoxide settles on top of the biodiesel.
In this test no glycerine settled out and the methoxide settled on top of the biodiesel and both were crystal clear.
So which test is right.
Why doesnt the dr pepper test make glycerine settle out if the biodiesel does not gel which if it does not gel means its not a complete conversion.
