3.5 or 5 grams?
Ive seen several tutorial videos on using the numbers you get off your titration and i am a litle confused. Some say to add 5g to the number you got off your titration test and some say use 3.5g? Im using NAOH and i need official word. Also i have made 3 one liter batches in the past couple days and they are all coming out very thick with a solid mass in the bottoms of the bottle after seperation. Whats going on?

Using NAOH produces a solid glycerol that can be a problem, and the glycerol is toxic to plants and animals. KOH produces a liquid glycerol that is easier to handle and dispose of. I use my KOH based glycerol for fertilizer and as a dust suppressant for gravel roads. KOH based glycerol can also be used as an additive in animal feeds.
It does take a little more KOH than NAOH though, but I prefer using it over NAOH. The base amount for KOH is 7 for 100%. I use 90% which requires 7.9 as a base amount.

Always something new to keep up on. I had been using 5.5 g from the old data. Will try maybe 7.7 g? The KOH I use is supposedly around 92%. Sound about right?

By using 7.7 gms instead of 5.5 you should see faster reaction times, and settling times should be shorter also.

Will try it next batch. I leave it to settle overnight. Do use the 80/20 method or all at the same time? thanks again. (Sorry to steal the thread Kyle)
