Hi all!
I am currently doing trials on different fertilizer production methods. I want to make urea sulfate crystals from fertilizer grade urea granules (46% N) and sulfuric acid. I suspect it would be a straightforward process, dissolve the urea in acid and precipitate the crystals and separate it from the mother liquor. I however have no idea what the concentration of the acid should be, I suspect it should be diluted but don't know to what percentage. I do not want to use concentrated sulfuric acid due to obvious safety reasons. Internet search has not yielded a recipe to make this either.
I did a similar experiment successfully with urea and 52% phosphoric acid, and got a good yield of urea phosphate crystals.
Any help is appreciated!
Thanks
Rommie
