摘要： By dividing the known condensation of acetoacetic acid diol esters with phenols into two process steps, a reduction in the cost of the entire process can be achieved.Methyl acetoacetate is first condensed with a phenol and the methyl 3,3-bis(4-hydroxyalkylphenyl)butanoate formed is reacted with the desired diol in the presence of a transesterification catalyst. In this way only one acetoacetic ester is necessary for various final products. The final products are useful stabilizers for plastics, in particular polyolefins.

摘要： The invention relates to a process for the preparation of polyalkyl-1-oxa-diazaspirodecane compounds, which can be used as highly active light stabilizers for polymers. The reaction is carried out in a solvent mixture of at least one alcohol and if appropriate an inert organic solvent in the presence of solid alkali metal hydroxide or a corresponding amount of a mixture of solid alkali metal hydroxide and water as the sole catalyst. The process offers the advantage that, by using a solvent mixture and dispensing with a phase transfer catalyst, a higher rate of reaction and therefore higher product quality with the same yield are achieved. By dispensing with a phase transfer catalyst, which remains in the waste water and must be disposed of expensively, and by the reusability of the solvent mixture, the process is more environment-friendly and more economical than processes known to date.
摘要翻译：本发明涉及可用作聚合物的高活性光稳定剂的聚烷基-1-氧杂 - 二氮杂螺十一烷化合物的制备方法。该反应在固体碱金属氢氧化物或相应量的固体碱金属氢氧化物和水的混合物作为唯一催化剂存在下，在至少一种醇和适当的惰性有机溶剂的溶剂混合物中进行。该方法具有以下优点：通过使用溶剂混合物并分配相转移催化剂，获得更高的反应速率并因此获得相同产率的较高产物质量。通过分配残留在废水中并必须经过昂贵处置的相转移催化剂，并且通过溶剂混合物的可再利用性，该方法比迄今为止已知的方法更环保并且更经济。
