Warnqvest Conversion Test (3/27 27/3)
The Warnqvest Conversion test has become the De Facto Standard to which a large number of home brewers are now attempting to make their biodiesel
Jan Warnqvist's Conversion Test
This is a quick Pass/Fail conversion test for your biodiesel and works because biodiesel will disolve into methanol while triglycerides do not disolve in methanol.
It works with washed and dried, or unwashed biodiesel that is well settled.
Equipment needed
1. Something to measure out 27 ml of methanol.
2. A small container in which to put the 27ml of methanol. I used a small glass jar about 11cm (4.5”) high and 5cm (2.5”) across
3. A 3ml syringe without the sharp. These cost me 15c each from my pharmacy and I used a new one for each test.
4. Biodiesel to be tested.
Procedure
1. Insure the jar is spotlessly clean and dry.
2. Put 27ml of room temperature methanol into the jar.
3. Use the syringe to put exactly 3ml of the biodiesel under test into the methanol.
4. Put top on Jar.
5. Shake jar hard for 5 seconds.
If the biodiesel completely dissolves into the methanol and no oil settles out on the bottom of the container you have very high conversion biodiesel.
Further GC Testing by RickDaTech shows:
"There have been a number of posts lately where people observed cloudiness even when they made high conversion fuel. In one case the sample failed for cloudiness, but passed GC testing for total glycerin. In addition I've found in my own testing that a number of variables combined influence the cloudiness.
Precipitation alone is enough of a test and it does raise the bar considerably. From my tests, it appears that if there is no precipitation, then the odds are in favor of the fuel meeting ASTM spec for bound glycerin. Also if there is precipitation, then you are highly unlikely to meet ASTM spec for bound glycerin."
