Abstract

A process for the removal of biuret from a saturated solution of urea containing biuret, in which the solution is first diluted and cooled so that a suspension of urea crystals and crystals of a double salt of urea and biuret is produced, then this crystal suspension is diluted with so much water that all the crystallized urea dissolves again, while at the same time subtracting heat from the solution and that the remaining biuret crystals are again separated from the solution.
