don't use toluene, it is not working at all .
I think steam destination is the best.
my black liquid transfer to a light yellow liquid.
but it takes a long time, and my first try was not so good.
I had only a little from 100ml black liquid.
my next try I use a 3 neck flask, I connect my pear shape separator funnel to it and fill with water.
slowly, dropwise, add the water to the flask where my black liquid is located.
every time the water connect with the black liquid, you get steam .
this steam reflux and collect it in a cylinder
Normal ether controlled liquid is not allowed to be sold in my country.
