标 题:Synthesis of a dendritic polyalcohol

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.

标题:Process for preparation of a dendritic polyol

摘要:A process for synthesis of a polymeric polyalcohol substantially and preferably built up form polyester units and composed of a monomeric or polymeric initiator molecule to which at least one dentritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymericor monomeric branching chain extender having three reactive functions of which two are hydroxyl groups. The two hydroxyl groups of the ranching chain extender is acetal protected by reaction between said two hydroxyl groups and an acetal-forming carbonyl compound, preferably an aldehyde. The acetal protected branching chain extender is then employed for addition to the initiator molecule of a first branching generation followed by an optional deprotection of the hydroxyl groups by decomposition of acetals and for addition in repeated steps of further branching generations. Additions of branching generations individually employ an acetal protected branching chain extender synthesized from the same or a different branching chain extender and/or acetal-forming carbonyl compound and addition of a branching generation is optionally followed by addition of a spacing generation.

摘要:A method for the high-purity synthesis of a diorganopolysiloxane having a functional group at only one molecular chain terminal, that is characterized by the preliminary silylation with a silylating agent of the silanol group-containing impurity present in the cyclic trisiloxane, and that is characterized by preliminarily converting the silanol group-containing impurity in the cyclic trisiloxane into a lithiated material by lithiation with an organolithium compound and then silylating this lithiated material using a silylating agent that contains silicon-bonded halogen.
