    Abstract: PROBLEM TO BE SOLVED: To obtain a corresponding pyrrole by dehydrogenating a pyrrolidine or a substituted pyrrolidine with a catalyst. SOLUTION: In a method for producing a pyrrole expressed by formula (R1 R2, R3 and R4 are each the same or different and express each H, a 1-12C alkyl or a 3-12C cycloalkyl) by dehydrogenating a pyrrolidine expressed by formula II in the presence of a supported noble metal catalyst, the dehydrogenation is carried out at 150-300 deg.C and 0.01-50 bar pressure, the noble metal catalyst contains 30-100 mass % of a) palladium on a rare earth oxide or an oxide of the forth family element (transition family IV) or b) a platinum/palladium mixture on aluminum oxide, a rare earth oxide or an oxide of the forth family element and 0-70 mass % of an alkali metal oxide or an alkaline earth metal oxide.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing anhydrous 2-amino-1- methoxypropane, capable of obtaining a desired product in high yield. SOLUTION: (a) Two phases comprising a reaction mixture and sodium hydroxide solution, obtained by reaction of 1-methoxy-2-propanol with ammonia on a catalyst are formed and (b) 2-amino-1-methoxypropane-containing phase is separated from water phase and (c) 2-amino-1-methoxypropane-containing phase is subjected to azeotropic distillation to produce an azeotropic mixture at first and the azeotropic mixture is returned to a process (a) or (b), and then, anhydrous 2-amino-1-methoxypropane is produced.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for purifying crude pyrrolidine capable of presenting a pyrrolidine composition comprising more than 99 m/m% of pyrrolidine and less than 0.3 m/m% of water. SOLUTION: This method for purifying crude pyrrolidine comprises continuously distill crude pyrrolidine comprising 40-98 m/m% of pyrrolidine and having more than 2 m/m% of water content in a column having a stripping zone and rectifying zone at

    Abstract: PROBLEM TO BE SOLVED: To provide an effective and economical method for producing pure triethylenediamine(TEDA) and its solution. SOLUTION: This method for producing pure triethylenediamine solution comprises evaporating triethylenediamine and introducing the gas state triethylenediamine into a liquid solvent. The gaseous triethylendiamine is obtained from the top of a column or its side discharging port. Further, the pure triethylenediamine solution is produced by following the above method and then crystallizing the triethylenediamine from the solution. The liquid solvent is selected from the group consisting of cyclic or non-cyclic hydrocarbons, chlorinated aliphatic hydrocarbons, aromatic hydrocarbons, alcohols, ketones, aliphatic carboxylic acid esters, aliphatic nitriles and ethers.

    Abstract: 2,2'-Dimorpholinodiethyl ether is produced by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen. The active hydrogenation catalyst, before reduction with hydrogen, contains 20-85 wt.% alumina, zirconium dioxide, titanium dioxide and/or silica, 1-70 wt.% copper oxide (CuO), less than 20 wt.% nickel oxide with respect to CuO and 0-50 wt.% other metal oxide(s). In the production of 2,2'-dimorpholinodiethyl ether (DMDEE) by reacting diethylene glycol with ammonia under pressure at elevated temperature in the presence of hydrogen and a hydrogenation catalyst, the active catalyst, before reduction with hydrogen, contains 20-85 wt.% aluminum oxide (Al2O3), zirconium dioxide (ZrO2), titanium dioxide (TiO2) and/or silica (SiO2), 1-70 wt.% copper oxide (expressed as CuO), 0-50 wt.% magnesium, chromium, zinc, barium and/or calcium oxide (expressed as MgO, Cr2O3, ZnO, BaO and CaO) and less than 20 wt.% nickel oxide (expressed as NiO) with respect to CuO.
