Abstract
Los hidróxidos de doble capa son materiales pertenecientes a las arcillas aniónicas. Dichas arcillas pueden ser modificadas con determinados metales de manera de impartirles carácter básico para ser utilizadas en reacciones de química fina. En este trabajo se presenta el estudio realizado a los hidróxidos de doble capa incorporados por el método de coprecipitación, con metales como el Zn, Ni, La y Ce. Dichos materiales presentaron buena estructura, área superficial y alta basicidad. En cuanto a la actividad catalítica, se estudió la reacción de condensación para la obtención de chalconas, obteniéndose conversiones por encima de 80% con altas selectividades y pureza del producto deseado.
The layered double hydroxides are like anionic clays materials. These clays can be modified with certain metals in order to impart a basic character for use in fine chemical reactions. In this work the study of double layer hydroxides incorporated by coprecipitation method with metals such as Zn, Ni, La and Ce is presented. These materials showed good structure, surface area and high basicity. The catalytic activity, the condensation reaction was studied to obtain chalcones, conversions were higher than 80% with high selectivity and purity of the desired product.
