Hi,
I did couple of tests on glycerin separation with the titration method on JTF with different results.
Test One;
250ml byproduct
10ml phosphoric
shacked vigorously
There was separation with 3 layers about 60/30/10 within about 15 minutes. FFa Glycerin and fluffy white sodium phosphate
Test two;
250ml byproduct
10ml phosphoric
shaked vigorously
I then added 5ml phosphoric
shaked vigorously
I added more phosphoric to see what would happen.
there was separation with In about one minute with two layers about 50/50 with creamy brown stuff on the bottom. FFa on top
I then added more phosphoric until I got separation of a reddish colour on bottom. this has being sitting for 4 hours or so.
In the jar there is about 60/40 (ffa/glycerin) with a very fine white layer on the bottom.
There is a greater amount of glycerin in test two and less ffa
Could any one explain to me what is happening?
John
