    Abstract: A PROCESS IS PROPOSED FOR PREPARING ACID FORMATES IN WHICH - A LIQUID STREAM I COMPRISING FORMIC ACID AND - A LIQUID STREAM II COMPRISING A METAL FORMATE ARE PREPARED, THE LIQUID STREAMS I AND II ARE FED TO A RECTIFICATION COLUMN IN SUCH A MANNER THAT A HIGHER OR IDENTICAL FEED POINT TO THE RECTIFICATION COLUMN IS CHOSEN FOR THE LIQUID STREAM II THAN FOR THE LIQUID STREAM I,THE LIQUID STREAMS I AND II ARE MIXED IN THE RECTIFICATION COLUMN, WITH WATER BEING REMOVED OVERHEAD FROM THE RECTIFICATION COLUMN AND A BOTTOMS STREAM COMPRISING THE ACID FORMATE IS TAKEN OFF FROM THE RECTIFICATION COLUMN,WHICH COMPRISES THE BOTTOMS STREAM BEING PRODUCED AS MELT COMPRISING LESS THAN 0.5% BY WEIGHT OF WATER.(FIG 1)

    Abstract: Procedimiento para la obtención de formiatos de ácido fórmico, según el cual - se pone a disposición una corriente líquida I, que contiene ácido fórmico, y - una corriente líquida II, que contiene un formiato metálico, las corrientes líquidas I y II se alimentan a una columna de rectificación de modo que para la corriente líquida II se selecciona un punto de alimentación más elevado, o el mismo que para la corriente líquida I para la columna de rectificación, las corrientes líquidas I y II se mezclan en la columna de rectificación bajo separación de agua a través de la columna de rectificación, y de la columna de rectificación se extrae una corriente de cola que contiene el formiato de ácido fórmico, caracterizado porque se obtiene la corriente de cola como fusión, que contiene menos de un 0, 5 % en peso de agua.

    Abstract: Propionic acid-containing composition (A) in solid and preferably pure form, comprises at least a metal compound (I). Propionic acid-containing composition (A) in solid and preferably pure form, comprises at least a metal compound (I) of formula ((M(n+))(H +>) x(CH 3CH 2C(O)O ->) (n+x)). M(n+) : n-valent alkalimetal- or alkaline earth metal cation; n : 1 or 2; and x : 0.25-5. Provided that when M(n+) is potassium, then x is not equal to 0.75-1.75. An independent claim is also included for the preparations of (A) comprising: either heating a neutral alkalimetal- and/or alkaline earth metal propionate and propionic acid in a molar ratio of 1:0.25 to 1:5 to give a homogeneous mixture and partially solidifying the homogeneous mixture, where the homogeneous mixture contains less than 1 wt.% of water; or heating a neutral alkalimetal- and/or alkaline earth metal propionate and propionic acid in a molar ratio of 1:0.25 to 1:5 to give a homogeneous mixture and crystallizing the homogeneous mixture, where the homogeneous mixture contains 1-15 wt.% of water and the molar ratio of the neutral alkali metal- and/or alkaline earth metal propionate to propionic acid is 1:0.75 to 1:1.75 if M(n+) is potassium.

    IPC: C07C20100101

    Abstract: The calculation of the above balance shows that the division of stream (5) into the streams (5a) and (5b) used here leads to the fact that in the neutralization stage no excess sodium formate is produced, so that any ejection can be omitted. Furthermore, the water content of the stream (14) comprising sodium formate recirculated to the first crystallization stage in this case can be set to a very low value.
