The process of urea adduct formation in a solid phase reaction has been investigated by differential thermal analysis, X-ray diffraction analysis and microscopic analysis. As a result, it has been confirmed that the urea adduct has been irreversiblly formed from the mixture of urea and solid fatty acid in a solid phase reaction, and the exothermic reaction in the urea adduct formation occured at the temperature below the melting point of both starting materials. The rapid development of a hexagonal prizm crystal of urea adduct can be easily observed under the microscope.
