摘要： Disclosed is a process for performing a reductive amination of a first functional group in an organic feed substrate, which feed substrate comprises at least one further functional group containing a halogen atom, wherein the halogen atom is selected from the list consisting of chlorine, bromine, iodine, and combinations thereof, in the presence of hydrogen and a heterogeneous catalyst comprising at least one metal from the list of Pd, Pt, Rh, Ir, and Ru, and in absence of any catalytic amount of any second metal from the list consisting of Ag, Ni, Co, Sn, Bi, Cu, Au, and combinations thereof. The process is preferably applied for the reductive amination of 2-chloro-benzaldehyde to form 2-chloro-benzyldimethylamine, as an intermediate in the production of active agrochemical compounds and microbicides of the methoximinophenylglyoxylic ester series.

摘要： The application relates to a process for drying a composition comprising an alkali metal salt of a compound of general formula (I) R1R2N—CHR3—COOM or formula (II) R1R2N—CHR3CHR3—COOM, in particular N,N-dimethyl glycinate salt, and the use thereof. In the process, the composition, in particular the N,N-di methyl glycinate salt, is dried by feeding the composition into a fluidized bed dryer and subjecting the composition to a heat treatment by contacting the composition in the fluidized bed dryer with a drying gas stream, and during the heat treatment a solution or dispersion of the composition is sprayed onto at least a portion of the composition present in the fluidized bed dryer, or alternatively or in addition the composition, in particular N,N-dimethyl glycinate salt, is fed into a fluidized bed dryer and subjected to heat treatment in the fluidized bed dryer by contacting the composition with a drying gas stream, and the temperature of the composition in the fluidized bed during the heat treatment does not exceed 50° C.

摘要： Disclosed is a process for performing a reductive amination of a first functional group in an organic feed substrate, which feed substrate comprises at least one further functional group containing a halogen atom, in the presence of hydrogen, a nitrogen-containing compound, and a catalyst, wherein the presence of the nitrogen-containing compound, expressed in a molar ratio relative to the first functional group in the organic feed substrate, at least during the reaction as long as the conversion of the organic feed substrate has not yet reached 80%, is maintained below a level of 1.3. Further disclosed is a composition of the invention comprising at least 98.0% wt of 2-chloro-benzyl-dimethylamine, at most 0.60% wt of the meso-o-Cl-BDMA dimer and at least 1 ppm wt of the (+/−)-o-Cl-BDMA dimer and any use therefor.
