What do you pay for methanol? It shouldn't be too expensive if you get it in bulk. >and keith, i'm not trying the palm oil, but the >coconut oil. what will be if i use the palm oil ? may >i know what oil have been used by you and the other ? Just about everything, I think. Coconut oil should be fine. Someone once said you could even use earwax! >i got another question : >1. i made my biodiesel, but in the end, i have one >separated glycerine is still liquid even in the room >temperature ( isn't the temperature to keep glycerine >in liquid is above of 38 C ? ) and i got one still >solid even in 40 C and semi gel in 50 C.

I can't follow this, it's not clear what you're doing. I can only say it again: use pure ingredients, 99%+ methanol, pure NaOH, and keep it dry! Take care with the titration - it seems you're not being careful enough, achieving such erratic results. Do the titration a couple of times to make sure of your results. Also you haven't said if you're using new or used coconut oil - is it new? Then you don't need to do titration, just use 3.5gm. Thousands of people are using Mike Pelly's method with consistent results, you shouldn't be failing if you're following the instructions properly.
