Abstract

"PROCESSO CONTìNUO DE PREPARO DE LACTATO DE ETILA". A invenção se refere a um processo contínuo de preparo de lactato de etila por esterificação de ácido láctico por meio do etanol, em presença de um catalisador que consiste em extrair em contínuo, do meio reacional de esterificação a uma taxa de conversão parcial do ácido láctico, uma mistura que compreende lactato de etila, etanol, água e diversos produtos pesados, depois de se submeter essa mistura a uma separação flash, sob pressão reduzida, da qual sai um fluxo de cabeça, compreendendo uma mistura de lactato de etila, de etanol e de água, mistura essa que alimenta, em sua parte baixa, uma coluna de destilação fracionada.
