Other Titles: | Preparación de carbamatos con catalizadores sólidos | Authors: | Corma, Avelino CSIC ORCID; Juárez Marín, Raquel; García Gómez, Hermenegildo | Keywords: | Carbamates Solid catalysts |
Issue Date: | 7-Jan-2010 | Citation: | WO2010000888 A1 | Abstract: | [EN] Procedure for preparing carbamates comprising reaction between at least: an amine or polyamines, an organic c~bonateo f formula (OR)(OR')C=O, a catalyst formed at least by a support selected from among at least a metal oxide, a microporous material, a mesoporous material, an anionic laminar compound of the hydrotalcite type or derivatives thereof or an organic polymer and which may also contain a metal from groups 8, 9, 10 and 11 of the periodic system. The carbamates obtained may be converted into the corresponding isocyanates thereof. [ES] Procedimiento de preparación de carbamatos que comprende, la reacción entre al menos: - una amina o poliaminas, - un carbonato orgánico de fórmula (OR)(OR")C=O, - un catalizador que está formado por al menos un soporte seleccionado entre al menos un óxido metálico, un material microporoso, un material mesoporoso, un compuesto laminar aniónico del tipo hidrotalcita o sus derivados o un polímero orgánico y que puede además contener un metal de los grupos 8, 9, 10 y 11 del sistema periódico. Los carbonatos obtenidos pueden ser transformados en sus correspondientes isocianatos. |
