  • Patent number: 10544087
    Abstract: 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.
    Type: Grant

  • Patent number: 9926241
    Abstract: A catalyst bed system, and a dehydrogenation process using the same, including a horizontal catalyst bed having a mixture of at least one catalytic material and at least one first inert material, a predetermined volume of at least one second inert material arranged upstream of the catalyst bed, wherein the volume of the reactor above the catalyst bed system is not filled by any solid material (empty space). The volume of the second inert material and the volume of the reactor above the second inert material (empty space) is between 0.04 and 0.73, preferably between 0.06 and 0.3, most preferably between 0.09 and 0.2.
