Abstract (en)
[origin: WO2006077233A1] The invention relates to a method for producing a xylylene diamine by the heterogeneously catalysed hydration of a phthalodinitrile. According to the invention, the hydration is carried out in the presence of a cobalt skeleton catalyst, an alkali metal hydroxide and an alcohol and/or ether as the solvent, at an absolute pressure ranging between 1 and 100 bar and a temperature of between 40 and 150 °C.
