I told Livio if he couldn't get any methanol to mix in, the 1% water in the ethanol would have to be removed with quicklime or mol sieve, and the oil would have to be very clean and dry, well-refined. 280-320 ml ethanol, and 7g NaOH or 10g KOH, per liter of oil. Actually I arrived at the 7g NaOH empirically (it's the molar equivalent of 10g KOH, and it works!) -- the 10g KOH is standard in the literature, and seems to be the right amount empirically as well.

I sent the recipe to Livio direct, and then posted the correction to the group -- duhh! :-) I know the feeling well. For instance, I think you've corrected the over-hasty misspellings in my last message (thanks!). KOK, I wrote, reactioon. Yeah - duhh! Anyway, the recipe is pretty obvious. I told Livio if he couldn't get any methanol to mix in, the 1% water in the ethanol would have to be removed with quicklime or mol sieve, and the oil would have to be very clean and dry, well-refined. 280-320 ml ethanol, In another message you said: For oil between 1.0 and 2.5, I use a mix of 3 parts ethanol to 1 part methanol. Below 1.0 I use a 7-to-1 mix. What proof ethanol are you using in the mix? You said elsewhere you got 90% with your still. 90% is good stuff, apart from being easier to make, nice of you could use it as-is like this. and 7g NaOH or 10g KOH, per liter of oil. Actually I arrived at the 7g NaOH empirically (it's the molar equivalent of 10g KOH, and it works!) Interesting - that double it rule for KOH always seemed a bit imprecise to me. -- the 10g KOH is standard in the literature, and seems to be the right amount empirically as well. Thanks a lot Ken, sorry to ply you with questions like this. I admire the work you're doing. All best Keith Addison Journey to Forever Handmade Projects Tokyo http://journeytoforever.org/ Yahoo!

That'll work better :-). Hi Ken Did you post the recipe? I can't find it. Also, that's 43% more KOH than NaOH. I've never used KOK, but most refs I've seen say you need twice as much KOH as NaOH.
