Paul,
I had the same problem dissolving the lye and for my test batches I "constructed" a Methanol shaker out of an old peristaltic pump motor and some wires. Result was: At room temperature with continuous agitation the lye dissolves within 30 - 60 minutes.

Schmidt" To: biofuel@yahoogroups.com <pschmidt cc: @madriver.com> Subject: Re: [biofuel] lye not dissolving? - physical mixing vs time 05.02.2004 16:16 Please respond to biofuel What I've read was that it can take anywhere from 12-24 or more hours. A very big time discrepency for what would seem to be a standard chemical reaction that use fixed amounts of chemicals. I work on technical manuals and things all day and can get caught up in semantics and exact wording to much, and this seems to be the case. Turns out the best reply would have been "NO, just give it more time..." as about 15 hours seemed to dissolve it all fine. Time worked just fine.. as you have noted. I'm still curious though as replies indiciate that the use of time is more of a dissolver than physical mixing. "... Prepare the sodium methoxide 12-24 hours in advance and time will do most of the dissolving for you, with perhaps an occasional bit of agitation." and "Once it's all added [ie the lye], replace the stopper and the lid, and swirl the mixture about for a few seconds. Then let it stand. Do that a few more times, every few hours or so (at least 4-6 times in all). It will be thoroughly dissolved in 24 hours, or maybe a bit longer." Fair enough. Time will indeed dissolve it quite well, no questions there. Does anybody know of any test, or personal paractises that have found that continuous shaking or stirring will decrease the time required to dissolve. I'm fine waiting a day after doing a titration for the methoxide to prepare, but if it's dissoved in 3-4 hours, ... that's an option I'd like to know about. Any "ph type" tests you can do to tell that anybody's heard about? Just looking for data out there. :) - Paul Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuels list archives: http://archive.nnytech.net/index.php?list=biofuel Please do NOT send Unsubscribe messages to the list address.
