There should be no water in the equation 2. When you titrate you are taking care of the Acid variable 3. I have no idea what you mean by variables in Wed, 16 May 2012 06:11:28 GMT bostonpyramidbuilder http://tech.groups.yahoo.com/group/Biodiesel/message/29024 http://tech.groups.yahoo.com/group/Biodiesel/message/29024 I was thinking that by measuring the reaction ( seeing if I'd pass the 27/3 test ) and then seeing how few G/L Of lye I could get away with and still get a Wed, 16 May 2012 05:08:28 GMT Tilly http://tech.groups.yahoo.com/group/Biodiesel/message/29023 http://tech.groups.yahoo.com/group/Biodiesel/message/29023 Testing has shown that to make biodiesel that meets ASTM conversion you need to use at least 5g NaOH as your base amount. 5.5g is ok.

I thought the base number for it was 5.5 ? Anyway I ran out monday and picked up some lab stuff, including a micro scale. Oh and ya I'm doing Wed, 16 May 2012 03:33:45 GMT Rick Bouvier http://tech.groups.yahoo.com/group/Biodiesel/message/29021 http://tech.groups.yahoo.com/group/Biodiesel/message/29021 B,   You didn't say if you are using KOH or NaOH. 5.5 grams per liter for a base would be a little high for NaOH and not enough for KOH. 5 grams per liter Wed, 16 May 2012 02:59:21 GMT Tilly http://tech.groups.yahoo.com/group/Biodiesel/message/29020 http://tech.groups.yahoo.com/group/Biodiesel/message/29020 What size batch are you calling a micro-batch? ! litre test batches are normally recommended Wed, 16 May 2012 02:56:29 GMT bostonpyramidbuilder http://tech.groups.yahoo.com/group/Biodiesel/message/29019 http://tech.groups.yahoo.com/group/Biodiesel/message/29019 well I've been reading up in a number of different forums and the general consensus is that micro-batch's are the first step to learning how to get good Mon, 14 May 2012 14:53:35 GMT Richard http://tech.groups.yahoo.com/group/Biodiesel/message/29018 http://tech.groups.yahoo.com/group/Biodiesel/message/29018 I ended up with usable BD. It took a lot of KOH of course and I ran the process for 4 1/2 hrs. I had a couple of batches that didn't convert well and I Mon, 14 May 2012 05:51:12 GMT Tilly http://tech.groups.yahoo.com/group/Biodiesel/message/29017 http://tech.groups.yahoo.com/group/Biodiesel/message/29017 Hi Richard, I am curious what kind of results you got with the oil titrating 22. I assume you use KOH instead of NaOH. I agree with Richard that a flat bottom Mon, 14 May 2012 04:54:21 GMT Richard http://tech.groups.yahoo.com/group/Biodiesel/message/29016 http://tech.groups.yahoo.com/group/Biodiesel/message/29016 You don't need a cone bottom. You can use a flat bottom 55 gal drum just as well. Your 7.3 is a good pick for bio diesel, but do not get into using WVO as it Mon, 14 May 2012 04:20:58 GMT bostonpyramidbuilder http://tech.groups.yahoo.com/group/Biodiesel/message/29015 http://tech.groups.yahoo.com/group/Biodiesel/message/29015 I've been reading along for quite some time now and collecting oil while I rebuild an old F250 I picked up for a shot of whiskey dead in a friends field.

I have performed a lot of distillation Sat, 12 May 2012 15:58:21 GMT lotus3390@... http://tech.groups.yahoo.com/group/Biodiesel/message/29013 http://tech.groups.yahoo.com/group/Biodiesel/message/29013 I am a small producer. I pretreat my wvo with the prior batch's glycerin. When the glycerin is drained away, there is very little methanol left in it (based
