Biodiesel from butter?

I've heard of research papers that talked about making biodiesel from butter, so I wanted to try it. I don't have access to the research paper itself, so I'm trying this blind.

What I tried is this:
- Melt butter
- Pour butter through acidic resin that is 1 inch in depth.
- Removed water with a turkey baster (used as a pipette).
- Added 5.5 grams of NaOH and 33% by volume of denatured alcohol I got from Home Depot
- Heated it for 3 hours.

The result was some sort of....wax... something that is DEFINITELY not biodiesel.
I tried the process again with the 'wax' and all I got was more wax. So something is CLEARLY wrong with the process, but I'm not sure what.

I'd like your thoughts on this.

Could the wax be butterfat?

That may be possible. I have no idea how to confirm this however.

Does anyone know about how I may be able to make biodiesel from butter?

I'd like your thoughts on this.
Denatured alcohol is likely to be what a lot of the world calls methylated spirts or "Metho"
This is usually around 95% Ethanol + bittering agent + probably water.
It is unlikely this will work for biodiesel production, probably too much water in it

Silly question brainy19, but why do you want to try to make bio from butter?

Are you a natural experimentalist?

Dgs,

In a way, I am. I've always loved science and love to tinker with random things. When I read that scientists found a way to make biodiesel form butter, I got curious.

Tilly,

Good advice. I'll try with methanol next time.
