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.
