Process for the preparation of perylene |
| abstract |
Process for the preparation of perylene by heating perylene carboxylic acids, their anhydrides or salts in the presence or absence of metals, metal oxides, hydroxides or carbonates to temperatures between 380-550 ° C, characterized in that one works at normal pressure or slightly reduced pressure and the resulting perylene is removed from the reaction vessel with an inert gas stream. The perylene obtained is characterized by high purity. |
