Title (EN) PROCESS FOR MAKING FORMIC ACID UTILIZING HIGHER-BOILING FORMATE ESTERS
(FR) PROCÉDÉ DE FABRICATION D'ACIDE FORMIQUE À L'AIDE D'ESTERS DE FORMIATE À POINT D'ÉBULLITION ÉLEVÉ
Abstract:
(EN) Disclosed is a process for recovering formic acid from a formate ester that allows for recovery of a formic acid product comprising greater than 75 wt.% formic acid. Disclosed is also a process for producing formic acid by carbonylating a carrier alcohol, hydrolyzing the formate ester of the carrier alcohol, and recovering a formic acid product comprising greater than 70 wt.% formic acid. Discloses are carrier alcohols that enable more favorable hydrolysis equilibriums and/or distillation sequences.
(FR) L'invention concerne un procédé de récupération d'acide formique à partir d'un ester de formiate qui permet la récupération d'un produit d'acide formique comprenant plus de 75 % en poids d'acide formique. L'invention concerne également un procédé de production d'acide formique par carbonylation d'un alcool porteur, l'hydrolyse de l'ester de formiate de l'alcool porteur, et la récupération d'un produit d'acide formique comprenant plus de 70 % en poids d'acide formique. L'invention concerne des alcools porteurs qui permettent d'obtenir des équilibres d'hydrolyse et/ou des séquences de distillation plus favorables.
