   Thinking about my procedure I don't think I could evaporate the solvent   
   very much since some of the borax would precipitate out as well. I don't   
   think I need to use Liquid-liquid extraction (LLE) techniques for this.   
      
   I'm sure if I had a Chem degree it would be helpful. I have read in a Chem   
   Journal that this reaction works but the Journal didn't give as much detail   
   as I need. I thought it might require a lot of study and digging to find   
   helpful   
   information so I thought I would post some questions here and responses have   
   been helpful. I do plan to potentially do some research but I'm just starting   
   to get my feet under me and it may take years from the sounds of it but I do   
   appreciate the constructive criticism.
