Abstract
"PROCESSO PAPA PRODUçãO DE SOLUçãO AQUOSA, ISENTA ESSENCIALMENTE DE ALCANOL". é divulgado um processo para a recuperação de formiltetraidrofuranos (FTHF's) produzidos pela hidroformilação catalisada por ródio de 2,5-dihidrofurano (2-5-DHF) onde os FTHF's são recuperados como uma mistura em equilíbrio de 2- e 3-FTHF e seus hidratos, 2- e 3[di(hidroxi)metil]tetraidrofurano de uma solução do produto de hidroformilação compreendendo um catalisador de ródio, 2- e 3-FTHF e um solvente orgânico de hidroformilação obtida como um produto líquido retirado de um processo de hidroformilação onde o 3-FTHF é produzido pela hidroformilação de 2,5-DHF. O 3-FTHF é um valioso intermediário orgânico útil, por exemplo, na preparação de 3-metiltetrahidrofurano e 3-aminometiltetrahidrofurano.
