This weekend I will be attempting to use KOH instead of Lye. I got a deal on a 50 lb bag of KOH but I don't know what the purity is. I'm not sure how to titrate to determine the purity so here is what I am going to try.
I'll make 3 batches, Batch 1 I will assume 99% pure and use 4.9 grams, batch 2 I will assume 92% pure and use 5.3 grams and batch 3 I will assume 85% purity and use 5.8 grams. I will be using new oil and see which batch turns out good and passes the shake test. Is this a good way to determine the purity? Any help is appreciated here. _______________________________________________ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/
