标 题:Synthesis of a dendritic polyalcohol
发明人：IHRE HENRIK; HULT ANDERS
权利人:PERSTORP AB; IHRE HENRIK; HULT ANDERS
摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

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:The present invention is directed to a method for the direct, one-step synthesis of crystalline segmented glycolide copolymers having less than 80 percent glycolide-based sequences in the copolyester chain. The copolyester chain can also be formed using a polyether glycol as the initiator for the ring-opening copolymerization of glycolide and other cyclic monomers to form highly hydrophilic materials.

摘要:The present invention is a method for synthesis of nucleic acids to amplify an intended nucleic acid in a region in which a GC content is rich, wherein a polyhydric alcohol and/or ammonium sulfate is present in an amplification reaction solution. According to the present invention, it is possible to amplify nucleic acids in a GC rich region efficiently and directly from a sample such as blood containing lots of PCR inhibitory substances without undergoing a process of isolating and purifying the nucleic acid, even though conducting PCR in the GC rich region tends to be difficult using conventional processes even if purified DNA is used.
