    Abstract: The invention concerns a device and a method for obtaining anhydrous or substantially anhydrous formic acid. Said device is partly or totally made of a zirconium-free material. A liquid of general formula (I) is used as extracting agent, wherein radicals R and R represent alkyl, cycloalkyl, aryl or aralkyl groups or R and R form together with the N atom a heterocyclic five or six-membered ring and in which only one of the radicals is an aryl group and in which R stands for hydrogen or a C1-C4-alkyl group. The device comprises the following equipment: (i) a synthesis reactor (6); (ii) a hydrolysis reactor (1); (iii) a first distillation device (2); (iv) a second distillation device (4); (v) an extraction device (3) and (vi) a third distillation device (5). The material has been selected from the group consisting of the following classes of materials: titanium-palladium alloys, nickel-based materials containing chrome, molybdenum, and/or wolfram and high-alloy, austenitic special chrome-nickel steels containing molybdenum.

    Abstract: The invention relates to an apparatus and a process for the preparation of anhydrous or substantially anhydrous formic acid. This apparatus is constructed partly or entirely of substantially zirconium-free materials. The extractant employed is a liquid of the general formula I where the radicals R 1 and R 2 are alkyl, cycloalkyl, aryl or aralkyl groups, or R 1 and R 2 jointly, together with the N atom, form a heterocyclic 5- or 6-membered ring, and only one of the radicals is an aryl group, and where R 3 is hydrogen or a C 1 -C 4 -alkyl group. The apparatus has a synthesis reactor ( 6 ), a hydrolysis reactor ( 1 ), three distillation devices ( 2,4,5 ) and an extraction device ( 3 ).

    Abstract: The invention relates to a process for obtaining anhydrous or substantially anhydrous formic acid, in which firstly aqueous formic acid is produced by hydrolysis of methyl formate, with the methanol content in the methyl formate having been reduced in advance. The process according to the invention has the special feature that-before the hydrolysis of the methyl formate-the methanol content of the methanol-containing methyl formate is reduced in a distillation column, this distillation column simultaneously being employed for other separation functions during work-up of the formic acid.
