Abstract: In a first aspect, the invention relates to a process for discoloration of a colored polymeric material comprising: (i) providing a colored polymeric material and providing a solvent comprising gamma-valerolactone: (ii) contacting the colored polymeric material with a solvent comprising gamma-valerolactone at a temperature in the range of from 40 to 170° C. thereby obtaining a solvent, which is enriched in colorant compared to the solvent provided in (i), and a polymeric material, which is depleted in colorant compared to the colored polymeric material provided in (i). A second aspect of the invention is related to a polymeric material, which is depleted in colorant obtained or obtainable from the process of the first aspect. In a third aspect, the invention is related to a use of the polymeric material, which is depleted in colorant according to the second aspect for textile applications, fiber applications, packaging applications or plastic applications. A fourth aspect of the invention is related to a method for preparing a textile or a packaging comprising (a) providing a polymeric material, which is depleted in colorant, preferably a polymeric material, which is depleted in colorant of the second aspect: (b) preparing a textile or a packaging from the polymeric material provided in (a).

Abstract: The present invention relates to a method for the regioselective hydroformylation of polyunsaturated acyclic hydrocarbons, which are 1, 3 butadienes, which, in the 2 position, bear a saturated or monounsaturated or polyunsaturated acyclic hydrocarbon radical. The present invention also relates to the production of secondary products of these hydroformylation products, especially of ambrox.
