Hello Rafal. About titration with phenolphthalein, before you increase the amount of it put some white reflecting material in the back and under the Erlenmeyer flask you will be using, increase the amount of light in your working area. Best Regards.

Hi all, For those who are interested. Just to let you know - I did another test with lye amount increased by the titration result, but it failed - emulsion (a bit less, but still). There're two possible reasons for that. One is that I had an accidental spill of methoxide when adding it to the oil Not much, but who knows what's enough... Another is that I should probably try to titrate with more intensive colour of phenolophtalein solution to say "that's it". I'm going to do one more try with more lye. -- cheers, Rafal Szczesniak **mir[at]diament.iit.pwr.wroc.pl Samba Team member mi***[at]samba.org +---------------------------------------------------------+ *BSD, GNU/Linux and Samba http://www.samba.org +---------------------------------------------------------+ _______________________________________________ ________ Information from NOD32 ________ This message was checked by NOD32 Antivirus System for Linux Mail Servers. http://www.eset.com _______________________________________________ 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/
