Abstract: The invention relates to a process for obtaining anhydrous or substantially anhydrous formic acid, in which firstly aqueous formic acid is prepared by hydrolysis of methyl formate and is freed from water in the subsequent work-up. The process has the special feature that steam, which is employed for the hydrolysis of methyl formate and for heating a distillation column serving for work-up, is also used as stripping steam for waste-water stripping. The stripped waste water is produced during work-up.

Abstract: Production of C5 acetate for vitamin A synthesis is by hydroformylation of 3,4-diacetoxybutene-1 (3,4-DABE) obtained in a stream resulting from a process in which butadiene has been catalytically acetoxylated with acetic acid and air and then distilled to separate off the 3,4-DABE-containing by-product.

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.
