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 :Process for synthesis of alpha, beta-unsaturated ketones
发明人：PATEL IAN; HOPES PHILIP
权利人:ASTRAZENECA AB
摘要:A method for the synthesis of an α,β-unsaturated ketone useful for making substituted 1,4-dihydropyridines is described by reacting an aldehyde with pyrrolidine and then adding a ketone followed by trifluoroacetic acid at low temperature. The synthesis is used in a process for making substituted 1,4-dihydropyridines wherein a vinylogous amide is prepared by reacting a 1,3-cyclohexanedione with a phenylethylamine. The α,β-unsaturated ketone can be reacted with a vinylogous amide to form a 1,5-diketone which can be converted to a substituted 1,4-dihydropyridine.

标 题 :ZSM-5 zeolite materials doped with fluorine species for the synthesis of MTBE and other acido-catalyzed reactions
发明人：MAO RAYMOND LE VAN
权利人:UNIV CONCORDIA
摘要:Provided herein is are acidic Z5M-5 zeollte materials which are highly active and selective in the synthesis of methyl tert-butyl ether (MTBE) and similar ethers. The materials are obtained by the preparation method comprising the main steps of: i) impregnation of zeolites with fluorine species using ammonium fluoride as precursor, preferably with a F loading of ca.1.9×10 3 mol.g −1 of zeolite; and ii) stepwise activation in air at preferably 250° C. and then preferably at 300° C. to 500° C., preferably 450° C. The method is preferably applied to desilicated ZSM-5 zeolite and provides conversion rates to MTBE superior to those obtained with prior art commercial AMBERLYSFâ„¢ resin (gas phase reaction at 70-80° C.) is obtained. No by-products, commonly produced by prior art commercial organic resin catalyst, are detected in the product spectrum.
