Does anyone know how a mix of 75% methanol with 35% ethanol would work for bio? I recently came across such a supply and want to know what my chances are of making it work. Any ideas?

BTW, it's all supposedly dry.

Thanks

Should work OK. KOH will dissolve easier than NaOH, and you might want to use slightly more total alcohol mix -- say, 25-30% of oil. Kick up the alkali a bit also, to maybe 6g + titr. NaOH, or 8.4g + titr. KOH.

You may have trouble getting the glycerine to drop out, particularly if you use high titrating oil. Or it may drop out on its own, but only after 12 hours....

Eric from some test batches I've done if you're titrating under 3 or so I think it'll work great will it pass 3/27? I don't know. The big batch I did with a similar ratio came out nasty at first then cleared. Yield was marginal at best probably fairly poor conversion, still good IDI fuel. I attribute the difficulties to high titrating oil and higher water content of the oil. Can you get a sample to test with your oil or do you have to buy a big qty?

I think I'll be able to get a small amount. The guy that told me about it just got 30 gallons of it the other day and is going to test it out. He's a real novice though with biodiesel so i'm not sure if he'll know whats going on and such...

Hey how much is that stuff costing if you don't mind. I might be interested in it. You could PM me if you don't want to post it here.

yaric: why do you need a 110% mix?

mostly because I love math
