Abstract
One aspect is a method for producing a first intermediate product. A feedstock is provided that comprises a first polyester. The first polyester is contacted with a further organic compound in a volume section Vto obtain a further initial mixture. A weight average molar mass of the first polyester is reduced in the volume section Vto obtain a first intermediate mixture. The first intermediate mixture comprises a first intermediate product and the further organic compound. First particulated material is added to the first intermediate mixture in a volume section V. A filtering means is pre-coated with the first particulated material. At least one impurity is at least partially removed from the first intermediate mixture using the filtering means. The first particulated material has a median pore diameter in the range of 5 mm to 20 mm.
