  • Patent number: 11891725
    Abstract: A method for recycling textiles comprising cellulose with the following steps of: optionally disintegrating the textile, swelling the cellulose, under reducing conditions, wherein at least one reducing agent is present at least during a part of the swelling, and then performing at least one of the following two bleaching steps in any order: i) bleaching the material with oxygen at alkaline conditions with a pH in the range 9-13.5, and ii) bleaching the material with ozone at acid conditions below pH 6. An advantage is that the yield is improved at the same time as excellent decolourization is achieved. If the recycled material is used in viscose manufacture, the risk of clogging nozzles and so on is reduced.

  • Patent number: 11872547
    Abstract: The present invention relates to a novel method for photocatalytic oxidation of allylic C—H bonds present in alkenes containing at least three carbon atoms. In this newly disclosed method, such alkenes, when reacted with carbon dioxide (CO2) in an organic solvent containing a catalyst comprising of a supported molecular complex of transition metal ions under conditions of ambient temperature and pressure using a readily available household LED lamp, yield oxygenated products. The developed method represents a unique way to use CO2 as an oxygen transfer agent to unsaturated organic compounds along with the formation of CO as a co-product using light as an energy source.
