I have just made my second batch of BD and I ran into some problems. I mixed the batch in the reactor for about 50 minutes and the reactor became very warm to the touch. The batch temperature raised to about 60 degrees C. I let it all settle overnight and today I drained off the Glycerine. The glycerine was very runny compared to my last batch. It was only a little thicker than water, however was still very dark in colour.
I pumped it all to the wash tank and washed it for 1hr 50 minutes by the bubble wash method. The wash tank became warm to the touch and there was a large amount of foam on top of the tank. I took a test sample of the BD and it was quite cloudy, however was a nice honey colour. There was a amount of cream coloured gunk floating on top of the BD (I assume this is soap)
My questions are:
1. Why was the glycerine so runny, isnt it meant to be fairly thick?
2. Why did the wash tank become hot and foam up?
3. Why is the BD cloudy? I washed the first batch twice (1 x 2hr and 1 x 10 hr) and it cleared fairly quickly. This stuff stays cloudy
I was thinking that I may have put too much catalyst into the mix and the heat in the wash tank was the mix still reacting.....
Thanks
