标 题:Synthesis of cyanurate and multifunctional alcohol-based polyether acrylate for uv curable materials

摘要:Polyether (meth)acrylates based on cyanuric acid or substituted cyanuric acid and multifunctional alcohol, which optionally include triethanolamine units, have wide applications in UV curable adhesives, coatings, inks, sealants, paints or 3D printing. These polyether acrylates have rigid cyanurate structure endowing the material with extra strength and thermal stability. Furthermore, triethanolamine unit, when present, endows the material with anti-oxygen inhibition property in UV curing process. These polyether (meth)acrylates have low viscosity and high reactivity towards UV curing. The cured resins have high resilience and strength. The process of making the polyether (meth)acrylates includes the synthesis of trifunctional polyether polyols through controlled polymerization of propylene oxide using multifunctional alcohol (such as glycerol and sucrose), cyanuric acid or substituted cyanuric acid, and optionally triethanolamine, in the presence of a catalyst, followed by the synthesis of polyether (meth)acrylates through transesterification or through direct esterification of the trifunctional polyether polyols.

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
权利人:BÃœTTNER HERMANN
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.
