Abstract

"PROCESSO PARA A PRODUçãO DE LACTIDA, PROCESSO PARA A PRODUçãO DE áCIDO POLILáTICO, PROCESSO PARA A PRODUçãO DE LACTATO DE ETILA, PROCESSO PARA A PRODUçãO DE éSTER DE LACTATO E PROCESSO PARA A PRODUçãO DE PRé-POLìMERO DE áCIDO LáTICO". De acordo com a presente invenção, um processo para produzir de modo consistente lactida a partir do lactato de amónio obtido por meio da fermentação lática, e um processo para a produção de modo consistente do ácido polilático a partir do lactato de amónio obtido por meio da fermentação lática, são proporcionados. Um processo para a produção de lactida, o qual compreende as etapas de: (1) síntese do éster de lactato a partir do lactato de amónio obtido por meio da fermentação lática; (2) policondensação do éster de lactato em presença de um catalisador outro que o monobutil-estanho, por meio do que o ácido polilático com um peso molecular ponderal médio de menos de 15.000 (pré-polímero do ácido lático) é sintetizado; e (3) despolimerização do ácido polilático, por meio do que a lactida é produzida. Um processo para a produção do ácido polilático, o qual compreende a etapa adicional (4) polimerização por abertura do anel da referida lactida, por meio do que o ácido polilático é obtido. Um processo para a produção do éster de lactato a partir do lactato de amónio obtido por meio da fermentação lática.
