Abstract

1 / 1 resumo “processo para preparar um ã�cido carboxã�lico 2,3- insaturadoâ€� a invenã§ã£o refere-se a uma composiã§ã£o de catalisador compreendendo um ã³xido misto de vanã¡dio, titã¢nio e fã³sforo. o componente titã¢nio ã© derivado de um composto de organotitã¢nio redox-ativo, solãºvel em ã¡gua. a composiã§ã£o de catalisador ã© altamente eficaz na facilitaã§ã£o da condensaã§ã£o da fase vapor de formaldeã­do com ã¡cido acã©tico, para gerar ã¡cido acrã­lico, particularmente usando uma alimentaã§ã£o liquida aquosa industrialmente relevante. adicionalmente, a composiã§ã£o de catalisador ã© cataliticamente ativa em relaã§ã£o ã  formaã§ã£o do ã¡cido acrã­lico de diacetato de metileno e ã¡cido metacrã­lico do dipropionato de metileno; ambas reaã§ãµes sã£o realizadas com elevados rendimentos espaã§o-temporais.1/1 Summary "Process for Preparing a 2,3-Unsaturated Carboxylic Acid" The invention relates to a catalyst composition comprising a mixed vanadium oxide, titanium and fan. The titanium component is derived from a water-soluble redox active organotitan compound. The catalyst composition is highly effective in facilitating the condensation of the vapor phase of formaldehyde with acetic acid to generate acrylic acid, particularly using a feed. It is industrially relevant aqueous liquid. furthermore, the catalyst composition is catalytically active with respect to the formation of methylene diacetate acrylic acid and methylene dipropionate methacrylic acid; Both reactions are performed with high spatiotemporal yields.
