标 题 :Method for the synchronous absorption of carbon dioxide from flue gas and synthesis of dialkyl carbonates and alkylene carbonates
发明人：BÃœTTNER HERMANN; Müller Jürgen; JONKER RAPHAEL; DOEDT SEBASTIAN; BOSSE TOBIAS; MAKRAN SEBASTIAN

摘要:The invention relates to a synchronous CCU method (carbon dioxide capture and utilisation) for the absorption of carbon dioxide from flue gas and other CO 2 -containing substance sources and simultaneous synthesis of dialkyl carbonates and alkylene carbonates. The general subject matter of the invention is, in terms of a 'carbon dioxide capture' on the one hand, the absorption of CO 2 from flue gas and other CO 2 -containing substance sources with ammonia and/or amines to form ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates and, in terms of a 'carbon dioxide utilisation' on the other hand, the reaction of ammonium carbamates or ammonium hydrogen carbonates or ureas or urea intermediates with aliphatic, alicyclic or unsaturated alcohols, and including unsaturated aromatic alcohols to give dialkyl carbonates or alkylene carbonates in such a form that the CO 2 n absorption agent is re-released and fed back into the repetitive process again. A repetitive process control is extremely energy and CO 2 n efficient.

摘要:Process for the preparation of polyalkylenepolyamines by homogeneously catalyzed alcohol amination, in which aliphatic amino alcohols are reacted with one another or aliphatic diamines or polyamines are reacted with aliphatic diols or polyols with the elimination of water in the presence of a homogeneous catalyst and in the presence of hydrogen gas. Polyalkylenepolyamines obtainable by such processes and polyalkylenepolyamines comprising hydroxy groups, secondary amines or tertiary amines. Uses of such polyalkylenepolyamines as adhesion promoters for printing inks, adhesion promoters in composite films, cohesion promoters for adhesives, crosslinkers/curing agents for resins, primers for paints, wet-adhesion promoters for emulsion paints, complexing agents and flocculating agents, penetration assistants in wood preservation, corrosion inhibitors, immobilizing agents for proteins and enzymes.
