 note = {The mechanism of the reaction of phenyl urea with formaldehyde in dioxane­water (4: 1) in the presence of sodium hydroxide has been studied from the view­point of the reaction rates and the diffusivities. 
The experimental reaction rate can be represented as follows
R= ₋ d〔F〕/dt = k〔C₆H₅NHCONH₂]².⁶〔NaOH〕².¹
From these results, we speculated that the mechanism of this reaction is uni molecular electrophilic substitution named S ᴇ 1. 
The diffusion coefficients of phenylurea and formaldehyde increase with each concentration in a lower range, which may be explained with the mechanism concluded from the experimental results of the reaction rate.},
