    Abstract: PROBLEM TO BE SOLVED: To provide a process for preparing n-butylamines by which the defects in the prior art are overcome, and the desired n-butylamine, or two or more desired n-butylamines can be produced in a high space time yield and selectivity. SOLUTION: An n-butenyl amine is produced by reacting 1,3-butadiene in a shape of a 1,3-butadiene-containing mixture obtained when cracking a petroleum fragment, or when dehydrogenating LPG or LNG, or obtained by a GTL (gas to liquid) technique, with a primary amine and/or a secondary amine under a hydroamination condition, and the provided butenylamine(s) is reacted with hydrogen under an alkyl-exchanging reaction condition at the second process step to provide the objective n-butylamines.

    Abstract: The present invention relates to a method for producing dialkylamides of the alkali metals by reacting the corresponding dialkylamine with the corresponding alkali metal in the presence of an electron donor substance of the group 1,3-butadiene, isoprene, naphthalene and/or styrene with the formation of low quantities of butenyl dialkylamine. According to said method, the corresponding alkali metal is introduced and suspended in a solvent and the dialkylamine and the electron donor substance are added, such that the dialkylamine is present in an amount up to 45 wt. %, preferably up to 25 wt. %, in particular up to 15 wt. % and the butadiene is present in an amount up to 5 wt. %, preferably up to 3 wt. %, in particular up to 1.5 wt. %.

    Abstract: The invention relates to a process for producing trioxane and at least one comonomer for producing (co)polymers on a trioxane basis, in which, in a first step, formaldehyde and at least one comonomer starting material are reacted in aqueous solution to form trioxane and comonomer, wherein a reaction mixture A1 containing trioxane, comonomer, formaldehyde, water and if appropriate comonomer starting material is obtained. In a second step, the reaction mixture A1 is distilled in a first distillation stage at a first pressure, wherein a trioxane- and comonomer-enriched stream B1 and an essentially water- , formaldehyde- and if appropriate comonomer starting material-containing stream B2 are obtained. In a third step, the stream B1 is distilled in a second distillation stage at a pressure which is above the pressure of the first distillation stage, wherein a trioxane-, comonomer- and water-containing stream C1 and a product stream C2 essentially consisting of comonomer and trioxane are obtained.

    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: The invention relates to a method for producing ethyldimethylamine and triethylamine, comprising the steps of (i) reacting a mixture from diethylamine and dimethylamine with ethylene in the presence of a catalyst from the group of the alkalimetal dimethylamides, alkalimetal diethylamides and alkalimetal hydrides, (ii) removing the catalyst, (iii) separating by distillation the obtained mixture into triethylamine and ethyldimethylamine and optionallydiethylamine and dimethylamine, (iv) optionally returning the catalyst and the educt amines to the reaction. The inventive method allows t he coupled production of ethyldimethylamine and diethylamine in a simple proces s.
