| abstract | The present invention relates to a process for the preparation of methylenedi (phenylurethane). It relates more particularly to the preparation of methylenedi (phenylurethane) by rearrangement of bis (N-carboalkoxyanilino) methanes, where appropriate in the presence of at least one alkyl N-phenylcarbamate, characterized in that the rearrangement is carried out in the presence hydrofluoric acid. |
