    Abstract: The invention relates to a method for producing linear alpha olefins by means of an isomerising metathetical reaction and ensuing ethenolysis. The method comprises the following steps: i) a C4-C10 olefin fraction is introduced into an isomerising metathesis reaction; ii) the mixture obtained is separated into a) a C2-C3-olefin fraction, b) a fraction containing olefins having the desired carbon count, c) a light fraction containing olefins having a carbon count of C4 or above, but below the carbon count of the desired fraction b) and, d) a heavy fraction containing olefins having a carbon count which is above the carbon count of the desired fraction b); iii) the light fraction c) and optionally the heavy fraction d) are redirected into the isomerising metathesis reaction i); iv) the fraction b) and optionally the fraction d) are introduced into an ethenolysis reaction; and v) the alpha olefin fraction produced in iv) is isolated. Linear C8-C12 alpha olefins can be especially produced using said method.

    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: A process is proposed for preparing acid formates by providing a liquid stream I containing formic acid and a liquid stream II containing a metal formate, and mixing the liquid stream I with the liquid stream II, obtaining the corresponding acid formate, which comprises feeding, to the liquid stream I or a precursor thereof, to the liquid stream II or a precursor thereof, or to the mixture of the liquid streams I and II, a liquid stream III containing the following components at contents of in each case >0.1% by weight: metal formate, metal methoxide, methanol and MeFo (MeFo), which is produced in a process for preparing MeFo by carbonylating methanol in a reactor at a pressure up to 50 MPa absolute in the presence of a metal methoxide as homogeneous catalyst.
