内容記述タイプ | Abstract | |||||
内容記述 | 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. |
