Abstract: 1,1'-Bis-(3-aminopropyl)-2,2'-diimidazole of the formula I, and a novel process for the preparation of 1,1'-bis-(3-aminopropyl)-2,2'-diimidazole of the formula I, in which 2,2'-diimidazole of the formula II, is reacted with acrylonitrile of the formula III, in the presence of basic catalysts at temperatures from 80 to 150 DEG C, and the product is hydrogenated with an excess of hydrogen on cobalt-, nickel-, ruthenium- and/or noble-metal-containing catalysts in the presence of ammonia, at temperatures from 40 to 200 DEG C and under pressures from 10 to 200 bar.

Abstract: Disclosed is a process for preparing aminopropionitriles of the general formula I, in which R represents a hydrogen atom or a methyl group. The process is characterized by reacting ammonia with acrylonitriles of the general formula II, wherein the substituent R is as specified above, in molar ratio ranging from 1 : 1 to 500 : 1 in the presence of oxides of the subsidiary group 7 or 8 of the Periodic System of Elements, acid or basic organic ion-exchange resins or mixtures thereof functioning as a heterogeneous catalyst at a temperature ranging from 40 to 180 degC and pressure within the range of 1.0 do 35.0 MPa.

Abstract: In the present invention there is described a process for preparing aminopropionitriles of the general formula I, in which R represents a hydrogen atom or a methyl group, by reacting ammonia with acrylonitrile of the general formula II, in which the substituent R is as defined above. The proposed preparation process is characterized in that reaction is carried out at molar ration of the reaction components of ammonia and acrylonitrile ranging from 1:1 to 500:1 on an oxide of element being selected from the second and/or the third and/or the fourth principal group of the Periodic System of Elements, from the second through the sixth auxiliary groups of the Periodic System of Elements, acid zeolite, phosphate and/or heteropolyacid or a mixture thereof, as on a heterogeneous catalyst at a temperature ranging from 40 to 180 degC and pressure in the range of 1.0 to 35.0 MPa.

Abstract: A process for the preparation of lactic acid esters by fermentation of mixtures containing sugars, conversion of the lactic acid resulting from the fermentation into its salts and subsequent esterification, characterised in that a) alkaline earth metal carbonate or bicarbonate is added to the fermentation broth in order to neutralise at least 50 mol% of the resulting lactic acid, b) the resulting fermentation broth is adjusted to a pH from 7 to 13 by adding NH3 and CO2, and the resulting precipitates are separated off, c) the ammonium lactate solution obtained and purified in this way is esterified with an alcohol
