Abstract

"PROCESSO PARA PREPARAR éSTERES DE áCIDO SUCCìNICO SUBSTITUìDOS COM ALQUILIDENO". Um processo para a preparação de succinatos alquilideno substituídos compreendendo uma etapa (a) na qual é executada a reação de um composto carbonílico, um succínico e uma base em um meio de reação e uma etapa (b) em que o produto alquilideno substituído obtido em (a) é esterificado; caracterizado do éster succínico ser usado numa quantidade molar substancialmente igual ou menor que a quantidade de composto carbonílico, (ii) a base é usada numa quantidade molar substancialmente igual à do éster succínico e é escolhida dentre os hidretos metálicos e alcóxidos, e (iii) o meio de reação compreende um meio líquido aprótico ou um meio líquido prótico tendo uma K~ a~, medida em água, inferior àquela de i-PrOH.
