Today’s cyclodextrin is about an agricultural application from SABIC.
In this invention, Sabic uses cyclodextrin for fertilizing via encapsulating urease inhibitors in a solidified nitrogen fertilizer melt.
The inhibitor (e.g., a nitrification and/or urease inhibitor), when complexed with the cyclodextrin, can be thermally stable at temperatures (e.g., 140 °C or more) exceeding the melt temperature of the nitrogen fertilizer. This can be advantageous in that the complexes can be contacted with and dispersed throughout molten nitrogen fertilizer with reduced, minimal, or no degradation of the inhibitors.
