摘要： The invention relates to a method for separating trioxane from a mixture containing formaldehyde, trioxane and water. According to said method: the mixture (1) is distilled in a first distillation stage (7) at a pressure of between 0.1 and 2 bar to obtain a stream (8) containing formaldehyde and a stream (9) containing predominantly trioxane, in addition to water and formaldehyde; the stream (9) is mixed with a recycling stream (19) containing predominantly trioxane, in addition to water and formaldehyde to form a stream (10) containing predominantly trioxane, in addition to water and formaldehyde; the stream (10) is then distilled in a second distillation stage (14) at a pressure of between 0.2 and 10 bar, optionally after the separation of low-boilers from the stream (9) or (10) in an additional distillation stage (11). The pressure in the second distillation stage (14) is at least 0.1 bar higher than the pressure in the first distillation stage (7). Said distillation produces a stream (15) consisting of trioxane and a stream (16) containing predominantly trioxane, in addition to water and formaldehyde. The stream (16) is then distilled in a third distillation stage (17) at a pressure of between 0.1 and 4 bar, to obtain a stream (18) containing predominantly water, in addition to formaldehyde and the recycling stream (19) containing predominantly trioxane, in addition to water and formaldehyde. The resultant stream (18) is optionally distilled in a fourth distillation stage (20), to obtain a stream (21) containing predominantly water and a stream (22) containing predominantly formaldehyde.

摘要： The invention relates to a method for producing polymethylol compounds of formula (I), in which R represents a further methylol group or an alkyl group with between 1 and 22 C atoms or an aryl or alkyl aryl group with between 6 and 22 C atoms, by condensating aldehydes with between 2 and 24 C atoms with formaldehyde, using tertiary amines as catalysts, with a view to obtaining compounds of formula (II), in which R has the meaning assigned to it above. The invention further relates to a process for hydrogenating polymethylol compounds by condensation in stages. For this, a) in a first (reaction) stage, the aldehydes with 2 or more C atoms are reacted with 2 to 8 times the molar quantity of formaldehyde in the presence of a tertiary amine as catalyst; b) in a second (separation) stage, either the reaction mixture is separated into a distillation residue containing primarily the compounds of formula (II) and a destillation flow containing primarily the compounds of unreacted or partly reacted starting materials which is fed back to the first stage, or the reaction mixture of the first stage is separated into an aqueous and an organic phase by means of a phase separation device and the organic phase fed back to the first stage, and c) in a third (post-reaction distillation) stage, the distillation residue of the second stage or the aqueous phase obtained by phase separation during the second stage is subjected to a catalytic and/or heat treatment, the compound of formula (III) which has not been fully methylolized is transformed into the corresponding compound of formula (II) and into the corresponding methylene compound of formula (IV), in which R' represents hydrogen or has the meaning assigned above to R, the reaction mixture obtained in this way is distilled, and the distillation overhead product, which contains a compound of formula (IV) and unreacted formaldehyde, is fed back to the first stage. Thereafter, the still bottom of this distillation process, which essentially contains the compound of formula (II), is hydrogenated in the known manner so as to obtain the corresponding end product of formula (I).

摘要： The invention relates to a method for the distillative separation of formaldehyde, from reaction mixtures containing a hydroxymethylated alkanal, said mixture being obtained from the reaction of formaldehyde with an alkanal, which comprises at least one acidic proton in a position α to the carbonyl function, or reaction of a 2-alkylacrolein or acrolein with water and formaldehyde, whereby said reaction is conducted in the presence of catalytic amounts of an organic amine. The invention is further characterised, in that before and/or during the distillation, a suitable amount of water is added. The method permits an improved separation of formaldehyde from the reaction mixture and, furthermore, permits an easier hydrogenation of the alkanals obtained thus to give polyols.

摘要： The invention relates to a method for carrying out the pure distillation of trimethylolpropane originating from the hydrogenation of 2,2-dimethylolbutanal with the following steps: (a) reacting n-butyraldehyde with formaldehyde in the presence of catalytic quantities of a tertiary amine and hydrogenating the mixture that is obtained in such a manner in order to form a mixture containing trimethylolpropane; (b) separating water, methanol, trialkylamine and/or trialkylammonium formate by distillation; (c) heating the remainder obtained in (b), under a vacuum, to a temperature at which TMP is volatile and at which compounds that boil at temperatures greater than that of TMP are cleaved while separating by distillation TMP as well as compounds that are less volatile than TMP; (d) distilling the distillate obtained in (c) while separating out the less volatile compounds and obtaining pure TMP; (e) carrying out the facultative distillation of the TMP obtained in (d) in order to obtain TMP that has a low alpha color index. The invention also relates to a method in which trialkylammonium formate is separated by distillation, while preserving the same, from raw mixtures consisting of polyvalent alcohols, mainly of trimethylolpropane.

摘要： The invention relates to a method for improving the yield in the production of polyhydric alcohols, by hydrogenation of hydroxymethylated alkanals, by decomposition of derivatives of said alcohols. 5 ppm to 1 wt. %, preferably 100 to 1000 ppm of a suitable acid is added to a water-free mixture, containing the said derivatives, the resulting mixture heated to a temperature of 100 to 300 DEG C and the polyvalent alcohol removed by distillation. The above method permits a simple and effective way of decomposing the undesired compounds formed during this synthesis that boil at a higher temperature than the polyhydric alcohol.

摘要： The invention relates to a method for carrying out the distillation or reactive distillation of a mixture containing at least one toxic constituent, whereby the method is carried out in a column provided with an ordered packing comprising at least one packing layer (1), which has a lower end (2) and an upper end (3) as well as an inner dimension that varies over its height. The invention provides that during the distillation or reactive distillation, a spouted bed with a mainly dispersed gas phase can be controlled in a specific manner in a first lower area (6) of the packing layer (1) and, at the same time, a film flow with a mainly continuous gas phase can be controlled in a second upper area (7) of the packing layer (1).
