    Abstract: The invention concerns a method for producing ethylamines and butylamines and ethylamine and butylamine mixtures. Said method comprises the following steps: (i) hydroamination of butadiene and ethylene with a monoalkylamine and/or dialkylamine, alkyl may be substituted by ethyl and/or butyl, in the presence of an alkali metal amide as catalyst; (ii) isomerization of the amine obtained during hydroamination (i), optionally after (iia) separating into specific fractions and/or (iib) in hydrogenation conditions and/or (iic) in the presence of ammonia; (iii) separating the product mixture obtained, isolating the desired amine produced and recycling to step (i) the appropriate amine as educt.

    Abstract: Described is a process for preparing substituted butenes of the formula I and/or II, (see formula I and/or II) where the radical R is unsubstituted or mono- or di-C1-C10-alkoxy-substituted or mono- or dihydroxy-substituted C2-C20-alkyl or alkenyl or is C6-C10-aryl, C7-C11-aralkyl or methyl by reacting 1,3-butadiene with an alcohol of the formula ROH in which R is as defined in the presence of an acidic particulate catalyst insoluble in the reaction medium, which involves contacting the butadiene, the alcohol and the catalyst in a fluidized bed reactor which is flow-approached from below and is operated at above the loosening paint.

    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: Preparation of trioxane and at least a comonomer for the preparation of (co)polymer on trioxane basis, comprises (a) converting formaldehyde and at least a co-monomer educt to trioxane and co-monomer in an aqueous solution to obtain a reaction mixture; (b) distilling the reaction mixture in a first distillation step at a first pressure to obtain stream (B1) and a stream (B2); and (c) distilling the stream (B1) in a second distillation step to obtain stream (C1) containing trioxane, co-monomer and water, and a product stream (C2) containing co-monomer and trioxane. Preparation of trioxane and at least a co-monomer for the preparation of (co)polymer on trioxane basis, comprises: (a) converting formaldehyde and at least a co-monomer educt to trioxane and co-monomer in an aqueous solution to obtain a reaction mixture containing trioxane, co-monomer, formaldehyde, water and optionally co-monomer educt, by synthesis step; (b) distilling the reaction mixture in a first distillation step at a first pressure to obtain stream (B1) enriched with trioxane and comonomer, and a stream (B2) containing water, formaldehyde and optionally comonomer-educt; and (c) distilling the stream (B1) in a second distillation step at a pressure above the pressure of the first distillation step to obtain stream (C1) containing trioxane, co-monomer and water, and a product stream (C2) containing co-monomer and trioxane.
