    Abstract: The invention relates to a method for producing formic acid formiates consisting in supplying a formic acid-containing fluid flow (I) and a metal formiate-containing fluid flow (II) and in mixing the fluid flow (I) and the fluid flow (II) in order to obtain corresponding formic acid formiate. Said invention is characterised in that a fluid flow (III) containing metallic formiate components, metal methanolate, methanol and formic acid methylester (MeFo) at a ratio > 0.1 mass % is inserted into the fluid flow (I) or the precursor thereof, into the fluid flow (II) or the precursor thereof or into a mixture which is formed by the fluid flows (I) and (II). Said fluid flow (II I) is obtained by a method for producing MeFo by carbonylating methanol in a reactor at a pressure up to 50 MPa absolutes in the presence of metal methanolate which used as homogenous catalyst.

    Abstract: Formic acid-formates are produced by (a) partial hydrolysis of methyl formate (MF) with water, (b) distillation to give (S1) formic acid and water, (c) conversion of the other product from (b) (mainly MF) into a stream (S2) containing formate and water by reaction with aqueous strong base and distillation of methanol, and (d) combination of (S1) with (S2). A method for the production of formic acid-formates (I) involves: (a) partial hydrolysis of methyl formate (MF) with water; (b) distillation to give a stream (S1) containing formic acid and water; (c) conversion of the MF- and possibly methanol-containing stream from (b) into a formate- and water-containing stream (S2) by (i) reaction with a basic compound of an acid with a pKa value of at least 3 in presence of water followed by (ii) removal of methanol by distillation; and (d) combination of streams (S1) and (S2). An Independent claim is also included for apparatus for the production of (I), comprising: (A) a reactor for the hydrolysis of MF; (B) a distillation column for separating a stream containing MF, formic acid, methanol and water; (C) a column for the hydrolysis of MF with a basic compound with removal of methanol by distillation (with an inlet for the base above the inlet for the product from (B)); and (D) a column connected to the bottom of (B) for removing water from the stream containing formic acid and water.

    Abstract: The invention relates to a method for producing formic acid formates, whereby (a) formic acid methyl ester is partially hydrolysed with water; (b) formic acid methyl ester and methanol are separated by distillation from the reaction mixture obtained in step (a), forming a current containing formic acid and water; (c) the current obtained in step (b), containing the formic acid methyl ester and optionally methanol, is converted into a current containing formate and water, by (i) reaction with a basic compound having a pKa value of the corresponding acid of the corresponding dissociation step of = 3, measured at 25 ~C in an aqueous solution, in the presence of water, and (ii) separation by distillation of the methanol; and (d) the current obtained in step (b), containing formic acid and water, and the current obtained in step (c), containing formate and water, are combined to form a mixture containing the formic acid formate and water. The invention also relates to a device for producing said formic acid formates and to the use of the same.

    Abstract: Acrolein and/or acrylic acid is prepared by feeding to a first reaction zone A at least two gaseous, propane-containing feed streams comprising fresh propane, and in reaction zone A, subjecting their propane fed to a heterogeneously catalyzed dehydrogenation to obtain a product gas mixture A comprising propane and propylene. Preparation of acrolein and/or acrylic acid involves feeding to a first reaction zone A at least two gaseous, propane-containing feed streams having fresh propane and in reaction zone A, subjecting their propane fed in this way to a heterogeneously catalyzed dehydrogenation to obtains a product gas mixture A comprising propane and propylene; conducting product gas mixture A out of reaction zone A and in a first separation zone A, removing a portion of the constituents other than propane and propylene in product gas mixture A and using remaining product gas mixture A' comprising propane and propylene; in a second reaction zone B to charge an oxidation reactor and, in the oxidation reaction, subjecting the propylene present in product gas mixture A' to a catalyst gas phase partial oxidation with molecular oxygen to give a product gas mixture B having acrolein or acrylic acid as the target product and also excess molecular oxygen; and conducting product gas mixture b out of reaction zone B and in a second separation zone, removing target product present in product gas mixture B, and of the remaining residual gas having unconverted propane, molecular oxygen and any unconverted propylene as one of the two-propane-containing feed streams into reaction zone A, where this recycling into he reaction zone A along the reaction path of the catalyzed dehydrogenation of propane in reaction zone A is effected such that at the feed point, >=5 mol.% of the propane fed to reaction zone A via the other feed streams has already been converted under dehydrogenating conditions in reaction zone A.
