    Abstract: Disclosed is a method for eliminating methacrylic acid from a liquid phase (P) containing acrylic acid as a main component and target product and methacrylic acid as a secondary component. According to said method, the methacrylic acid is eliminated using crystallization, the acrylic acid accumulating in the formed crystallized product and the methacrylic acid accumulating in the remaining mother liquor.

    Abstract: Preparation of at least one final product by partial oxidation and/or ammoxidation of propylene, comprises subjecting a purified propane to dehydrogenation; separating optionally the gas mixture containing propane and propylene, and simultaneously producing a propane and propylene containing gas mixture (II); subjecting the gas mixtures in heterogeneous catalyzed gasphase-partial oxidation, where a gas mixture (III) containing at least one final product is obtained; separating the gas mixture (III) and leading back at least propane in the remainder gas in the first reaction step. Preparation of at least one final product by partial oxidation and/or ammoxidation of propylene, comprises subjecting a propane, which is first purified in a first reaction step in the presence and/or absence of oxygen, to dehydrogenation comprising homogeneous dehydrogenation, heterogeneously catalyzed dehydration, homogeneous oxide-hydrogenation and heterogeneously catalyzed oxide-hydrogenation, where the non-reacted propane and formed propylene containing gas mixture (I) is obtained; separating optionally the total quantity or partial quantity of the gas mixture containing propane and propylene of different components and/or changing into other compounds, and simultaneously producing a propane and propylene containing gas mixture (II); subjecting the gas mixture (I) or (II), or a gas mixture, which is a mixture of formed gas mixture (II) and remained gas mixture (I) in heterogeneous catalyzed gasphase-partialoxidation and/or partial gasphase-ammoxidation of the gas mixture (I) and/or (II), where a gas mixture (III) containing at least one final product is obtained; and separating the gas mixture (III) and leading back at least propane in the remainder gas in the first reaction step, where the propane is pre-purified from raw propane, which contains >=90 wt.% of propane, =99 wt.% of propane and propylene, >=100 wt.% of 2C-hydrocarbon and >=100 wt.% of 4C-hydrocarbon, with the standard, that the raw propane leads to rectification column and takes place over the supply place of the purified propane, where the concentration of 2C-hydrocarbon of propane contained in the purified propane amounts to not more than 80 wt.% based on the content of raw propane and the concentration of 4C-hydrocarbon of propane contained in the purified propane amounts to a maximum of 50% based on the content of the raw propane.

    Abstract: A method for the production of formic acid-formates (I) involves (a) partial hydrolysis of methyl formate (MF) with water, (b) distillation to give formic acid and water (stream S1) and (c) combination of (S1) with the corresponding formate (F) to give a mixture of (I) and water. An Independent claim is also included for apparatus for the production of (I), comprising a reactor (A) for the hydrolysis of MF, a distillation column (B) for separating a stream containing MF, formic acid, methanol and water into MF, methanol and a stream (S1) containing formic acid and water, and a column (E) for removing water from S1.

    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.
