Thanks for the prompt reply keith. The keg is made of stainless steel & is probably double the size for my requirements. My reactor is a 200ltr drum which I'm hoping will provide several successful batches before the rust gets outta control. Best Regards CRAIG.

Hi Craig Your methox won't explode. I've never heard of such a thing, but it might (?) apply to the chemical called sodium methoxide which you can buy from chemical suppliers, I have no idea what the strength of it is, but what you mix yourself from methanol and lye is different, and the proportion of lye is low, especially in the Foolproof method. When mixing, add the lye bit by bit instead of all at once. Check the archives for recent messages here, especially from Todd and Alan, on mixing methoxide - see thread "acceptable containers for methoxide mixing". I recommend you do a couple of small (1 litre or less) test batches first to familiarise yourself with the process. Your methoxide stirrer is 50 litres?? How big is your reactor? What are beer kegs made of? Best Keith Yahoo!
