Latest Patents

Jentje holds a patent for a process designed to recover ammonium sulphate from an aqueous ammonium sulphate solution that contains organic contaminants. The patent describes a method where the aqueous solution is contacted with a water-soluble organic substance. This substance, in combination with a saturated ammonium sulphate solution, forms a two-layer system. The organic substances used are lactames with 4 to 20 carbon atoms. The process allows for the separation of the aqueous phase, which contains the ammonium sulphate, from the organic phase that holds the organic contaminants. This innovative method facilitates the crystallization of ammonium sulphate from the aqueous phase.
