Concentrations of equilibrium mixtures formed by adding increments of octene to a solution of urea in methanol to form adduct are reported.

Calorimetric studies indicate that the addition of octene to a urea-methanol solution shows an endothermic heat effect prior to the formation of solid adduct. The heat effect becomes exothermic as solid adduct is formed.

Addition of decane to an equilibrium octene-urea adduct system increased octene concentration in the supernatent liquid, indicating an octene release from the original adduct as decane adduct was formed.

The order in which decane and octene were added to form the decane-octene-urea adduct system was shown to influence the final equilibrium concentration of the adduct and its supernatent liquid.
