Abstract: The invention relates to a method for distillative separation of triethanolamin from a substance mixture consisting of mono- di-, and triethanolamin, ethanolamin-ether and water obtainable by an ammonia and ethylene oxide reaction in a liquid phase at a high pressure and temperature consisting in distilling the substance mixture in two stages. In the first stage, a low-boiling fraction and a high-boiling fraction are withdrawn and discharged, and in the second stage, a medium-boiling fractions is distilled at a triethanolamin content >99.4 % by weight and a diethanolamin content

Abstract: The invention relates to an apparatus and a process for the preparation of anhydrous or substantially anhydrous formic acid. This apparatus is constructed partly or entirely of substantially zirconium-free materials. The extractant employed is a liquid of the general formula I where the radicals R 1 and R 2 are alkyl, cycloalkyl, aryl or aralkyl groups, or R 1 and R 2 jointly, together with the N atom, form a heterocyclic 5- or 6-membered ring, and only one of the radicals is an aryl group, and where R 3 is hydrogen or a C 1 -C 4 -alkyl group. The apparatus has a synthesis reactor ( 6 ), a hydrolysis reactor ( 1 ), three distillation devices ( 2,4,5 ) and an extraction device ( 3 ).

Abstract: Process for separating triethanolamine continuously by distillation from a mixture of monoethanolamine, diethanolamine and triethanolamine together with ethanolamine ethers and water obtained by reaction of ammonia with ethylene oxide in the liquid phase under superatmospheric pressure and at elevated temperature, in which the mixture is distilled in two stages. The low-boiling fraction and the high-boiling fraction are taken off and discharged in the first stage and the intermediate-boiling fraction comprising >99.4% by weight of triethanolamine and

Abstract: A description is given of a process for preparing methyl formate by reacting excess methanol with carbon monoxide under superatmospheric pressure and at elevated temperature in the presence of alkali metal methoxide or alkaline earth metal methoxide as catalyst in a pressure-rated reactor, in which the use of at least two reactor elements, preferably operated in countercurrent, at about 100° C. and a pressure of about 100 bar in combination with a solids-free desalting of the reaction product makes possible very economical, largely trouble-free production of methyl formate in any desired quality and with a very good production capacity. Furthermore, the process for solids-free desalting and apparatuses for carrying out this process are described.

Abstract: The invention relates to a process for obtaining anhydrous or substantially anhydrous formic acid, in which firstly aqueous formic acid is produced by hydrolysis of methyl formate, with the methanol content in the methyl formate having been reduced in advance. The process according to the invention has the special feature that-before the hydrolysis of the methyl formate-the methanol content of the methanol-containing methyl formate is reduced in a distillation column, this distillation column simultaneously being employed for other separation functions during work-up of the formic acid.
