Method for preparing a purified cyclic compound composition

A method for preparing a purified cyclic compound composition, the method comprising:

• providing in a reactor a reaction mixture containing at least one cyclizable linear compound and reacting the at least one cyclizable linear compound in a ring-closing reaction so as to obtain a crude composition containing at least one cyclic compound,
• feeding at least a portion of the crude composition to a precipitator, the crude composition cooled to a precipitation temperature being below the solubility temperature of at least one of the at least one cyclic compound contained in the crude composition for precipitating at least a portion thereof so as to obtain precipitated solid cyclic compound and unprecipitated liquid,
• separating at least a portion of the precipitated solid cyclic compound from the unprecipitated liquid so as to obtain a solid cyclic compound fraction and unprecipitated liquid fraction, and
• washing the solid cyclic compound fraction with a washing solvent having a temperature of above the precipitation temperature so as to obtain a washing solvent fraction and as purified cyclic compound composition a washed solid cyclic compound fraction.
